Watch Reviews

Although this particular Seiko wasn’t on my radar, I knew I always wanted to check out one of their divers, or maybe an Alpinist, so when Dan ‘Jackson’ came by my place for a visit and offered one up as a trade it kind of went like this: https://youtu.be/uvqazhJJ01A?t=2

My everyday watch is an Omega Seamaster Planet Ocean ref 2201.50.00. I was guessing that this wouldn’t be kicking my PO off my wrist permanently, but also thought hey, why not. Life isn’t a practice run so I have to pull the trigger when it feels right. Right? It’s a nice watch at an apparently reasonable value. It’s also both blue and shiny which can be strong qualifiers for a guy like me. YOLO, just not in a frat boy kind of way. That might catch you a case. Kidding aside, with such a devout group of brand enthusiasts I had to give one of these a shake to see if Prospex Divers live up to the fanboy hype and deserve our money.

Now that it’s been a couple of weeks of wearing this every day I feel like I can share some opinions, but lets get the details out of the way first.

Just a note, while this watch was released as a “modern interpretation” of the 1965 62MAS. I’m not really feeling a strong connection as seen in the closely reproduced SLA017 Limited edition. The similarities could be compared to Battlefield V repping WWII so for the purpose of this review I won’t be making many comparisons. Following the design lineage of the Prospex line can, and should be its own article.

If you truly want a 62MAS though, the real deal, in reasonable vintage condition can still be found. Limited to 2000 units, a new SLA017 might be impossible to find brand new but I’ve seen lightly used ones pop up on Watch Recon for a little less that $3500 USD.

Fit

As a medium to large sized diver this doesn’t exactly melt into your wrist although its relative thickness at 13.8 mm keeps it from feeling like you are wearing a teetering brick. Its proportions help it stay put which is nice for people who prefer a looser fit like myself. In fact, it is surprisingly comfortable with the exception of the somewhat stabby crown which at the 3:00 position, occasionally reminds you that you are alive and didn’t actually drown in 1984.

It would be an improvement if the crown was slightly shrouded like on my PO, with a guard, or at 4:00 like on the SPB079J1. Sometimes referred to as a “retro” or “heritage” kind of crown position/look, I may refer to it as “mildly uncomfortable” but I digress. It will make you a man like they used to make men. Your dad’s, dad. Barefoot to school at 6:00 am in the freezing cold on broken glass kind of stuff. It’s not actually that bad. Mild is the key word here.

In retrospect I remember finding the PO’s crown noticeable as well, so it’s something I can easily say everyday users will forget about. Traveling forward in time, I have. Otherwise, all of the edges are flowing and well rendered which translates to a comfortable wear.

With my modest 7.25” wrist this fits well without looking ridiculous on the bracelet or (I’m guessing) stock strap. For you sneaker wearing low-brows this is comfy and looks sharp on a NATO too. If you are a bit weedy though, it may look more like a Pip-Boy 3000 than a watch, so something a bit more demure may suit your delicate wrist better. In these modern times, something > 40 mm would be my recommendation for you.

Movement

The movement is a calibre 6R15 (23 Jewels) which is a mid-range, in-house design that operates at 21,600 vph. It’s a step up from the Seiko 7S26 that’s found in the likes of the venerable SX007’s and other entry level mechanical Seikos.

I’ve heard of this movement referred to as both “tried and true” and “just a 7S26 with hacking and winding” hastily tacked on. On the other hand I’ve read that the movement’s support has been re-engineered enough that it deserves a distinction far beyond that of a modified 7S26. Honestly I’m just getting started with these Seikos so I still have some things to uncover over time but hey, that’s what the hobby (and comment section) is all about.

Personally I like the performance I’ve been getting out of this movement. I’m not hooking this thing up to my Timegrapher or anything. I just like to be on time and this gets me there without a daily check against my iPhone. Well not entirely true, during the time of this review I had periodically checked it against my phone and it seems close enough to me. I would say it safely sits well inside Seiko’s advertised tolerance of +25 to -15 seconds per day. Much tighter would be my guess but again, I haven’t any kind of real measure. Maybe when I get my mildly abused PO serviced I’ll have this watch regulated and share some more info on the movement when it is looked at by a proper watchmaker. In the meantime I’ll let the heritage boot guys banter about the faults or virtues of the 6R15 over a craft brew. You know who you are.

My only beef with this movement is how the date turns over. It starts to slowly creep just before 11:00 pm and finally, snaps into place at about 11:59. I’d like this to just snap over at 12:00 ish like my Omega. I’m a night owl so I’m always seeing this half turned over date. Maybe I’m just spoiled.

Circling back; movements without hand winding, a screw-down crown and to a lesser extent hacking are a deal breaker for me so this fits the bill. Having the date is also a big plus. As far as reliability, only time will tell. I tend to be pretty rough on my watch so if anyone will awaken the gremlins, I’m your man and will duly report.

A bit of trivia; Seiko is one of the few companies that makes their own mainsprings. They use their proprietary Spron 510 alloy which is also found in the balance spring. Spron helps gives this watch a 50-ish h power reserve which I seem to be getting most of. The alloy is similar to its Swiss counterpart Nivarox but not as high tech as newer alloys or the Silicon mixtures in the most current Rolexes, Omegas and their ilk.

Along with the aforementioned features the 6R15 includes Diashock which in this watch is basically a flat spring that cradles the balance wheel end stone and jewel helping to protect the balance against shock. I’m pretty sure most mechanical movements worth their salt have a decent one of these.

Case and Crown

The screw-down crown is a pleasure to use on this watch. Setting the time or “quick set” date is a smooth procedure. I’m also liking the wind which feels satisfying with its slightly audible ratcheting. A crisp, coin edge and fair size gives you a good grip for easy operation. If I could change one thing, I’d probably add some detailing to the cap of the crown which is “sterile”. Maybe the PX logo a “S” or “Seiko” like on some other models?

The case has a flowing shape with drilled, tapered lugs at 20mm apart. The face has a brushed finish that follows the circumference of the bezel. Moving toward the edge there is a highly polished bevel followed again by brushing on the outmost sides. The back is largely mirror polished, with the exception of a ring around the screw-down case-back that frames the embossed Prospex, Tsunami logo. I’m not crazy about the Tsunami Embossing. Maybe it will grow on me but it doesn’t capture my imagination at the moment. I prefer the dolphin logo which shouldn’t be cooler but kind of is. I personally like a more traditional depiction of the tsunami. There’s more info and the serial number, logo’s etc on the case back. All things you don’t really see but may admire when off your wrist in full nerd mode.

Overall, the case is attractive, with good attention to detail and thoughtfulness in its design. The workmanship is protected with a Seiko’s Diasheild which I’ve read is some type of PVD coating similar to what you would find on black-bladed knives or those gold-titanium coated drill bits. I have no reference as to how long this will last but so far so good. The bracelet must not be coated with the same stuff as it’s showing a fair bit of scuffing already, but nothing unexpected.

Dial, Bezel, and Crystal

The Dial is blue with a sunburst pattern. It presents a dark, near black color in low/artificial light and a vivid, bright royal blue in strong daylight. The indexes are oversized, made up of wide, applied, flat stainless borders and filled with Seiko’s LumiBrite. The signature consists of the Seiko logo on the top half with the Prospex logo, “Automatic” and “Diver’s 200m” on the bottom half.

There’s a chapter ring with a flange meeting the bezel with the hour and minute indexes. The primary lumed indexes are straight at 6 and 9 with a double width at 12:00. The others taper toward the dial’s centre. A chamfered date aperture is found at 3:00 which has a small white border giving it a tightly finished look. The Lume works great and keeps its glow for a long time.

I’ve read that some of these watches have alignment issues with the bezel and or chapter ring. I’m not seeing anything like that on this particular watch which looks to me, as expected. To be critical, It would have been nice if there was another applied element. Either the Seiko logo or Prospex logo would do and I’ve seen it done on Seiko models at a less than half the price. A little more detail would have me totally sold on this dial but I’m still about 85% there.

The handset is shared with the Seiko Tunas and includes a portly arrow for the hour and a slender rectangular minute hand that terminates at a blunted point. While not as elegant as some of the other Seiko diver hand sets, you can’t argue with the legibility. You could argue that the steel bordering on the hands could be polished to match the index borders and I wouldn’t disagree. I think it would help tie things together.

Back to legibility, the dial might be be better with more contrasting indexes like the bubbly ones found on the Tuna that these were borrowed from (I get that it’s supposed to reference the 62MAS). Either way it’s a pretty moot, enthusiast issue in my opinion. If you can’t read your watch you have other problems to address. The second hand is narrow with a lumed tail. The lume here is used to show that the watch is working, as per ISO 6425 (diver’s watch) standards.

The bezel is a 120 click, unidirectional that rotates counter-clockwise. As on the crown, a tight crisp coin edge makes it easy to get a hold of. That’s a good thing since the rotation is pretty firm, albeit smooth with a dampened feel. The insert is super polished, blue and with matte indexes and numbers. Like the dial, In low light the bezel almost appears black but presents a bright blue in daylight. While the bezel and dial aren’t exact in color, they compliment each other perfectly. There’s a lume pearl so the bezel position can be easily read in the depths.

The crystal is slightly domed with an antireflective coating on the inside. There’s not much to say here other than it looks great and it should stay that way since it’s a sapphire crystal, not Seikos cheaper Hardlex Mineral. If it’s anywhere near as hard as the one on my Omega, it will take more of beating than it will ever deserve. Before the crystal meets the bezel, there’s a generous bevel that is large enough to refract elements of the dial below. Since the dial is pretty simple, I feel that this adds a necessary detail. On a busier watch I appreciate it if the crystal flows into the bezel seamlessly.

Bracelet

This watch came with the Seiko M01X331H0 bracelet which is normally purchased separately.

It’s an attractive Oyster copy with a pinch button deployment clasp with a safety. There’s also a Diver’s extension. For the price the fit and finish is excellent. The links are brushed and have polished inner and outer edges. The inner edge polishing in particular, adds some luxe appeal without the associated premium.

If I were to adjust the bracelet aesthetically, I might give the clasp a little more love but to reiterate, at this price I have no legitimate complaints. Mechanically, the detent on the safety could be stronger. While it’s staying put now, I’m not sure if that will always be the case. Functionally it’s not a big concern since the main clasp is sturdy.

Speculating from photos, the stock silicone bracelet looks to have some inner texture so it should breath a little for comfort. The ends flow fluidly with the case, more so than the bracelet or a nato does. Not surprising though, since this strap is made for the watch. The pin buckle is polished while the keeper is brushed with an embossed Seiko logo.

The silicone strap’s accordion shape won’t be for everyone but it serves the practical purpose of working as a diver’s extension with the added function of maintaining a comfortable tension under variable pressures/wet and dry. If I was actually diving with this watch (which I won’t be), this would be the strap I’d use because its purpose built. At the desk I like the look of a Nato or the bracelet and I’ve read that these silicone straps are lint magnets.

Seiko SPB053 / SPB051 Watch Review – Final Thoughts

The Seiko ref. SPB053 is a sharp looking watch that has a sophisticated balance of conservative detailing and good functionality that references decades of Seiko diver designs. The stand out for me has to be the dynamic combination of dial and bezel that shows different personas depending on the lighting. This has been the most enjoyable aspect and I may have found it a touch too minimal otherwise.

As to be expected with all the Prospex line up, it meets the diver specifications outlined in ISO 6425, making it a viable mechanical alternative to a dive computer if you are feeling old school or want to look medium-fancy in your Y-40 swimming pool.

Value wise, there’s a lot of watch for your money here but the pricing/feature is still carefully measured. Seiko has amassed a following that they are clearly aware of by releasing such models, so while easily worth the ask, you aren’t getting an absurd amount of extra value – just what the brand is typically known for. That said, the fit, finish and function will satisfy.

As for me personally, the SPB053 has ticked enough boxes to put it in the recommend column, so long as you aren’t actually looking for a 62MAS and can pull off the larger 42.6 mm case.

An applied signature, polished hands and some detail on the crown would have made this even more competitive and memorable at a price point where there are some other tempting offers. Regardless, I’m understanding why people love the Prospex line. They have a compelling value proposition and wear well, dressed up (maybe not black tie) or down while maintaining that tool watch pedigree. There aren’t many divers around this price with a similar build quality and fewer with such a long and clearly documented design history.

The addition of a couple of Natos and the excellent bracelet will makes this considerably more enjoyable. The drilled lugs make for easy strap changes to get more life out of this beautiful watch.

If blue isn’t to your taste the model also comes in black as ref. SPB051. There’s also the SPB079J1, a similar type vintage inspired ‘re-issue’ that was previously mentioned and has worked its way onto my wish list.

Formed in 1892 in Lancaster, Pennsylvania, Hamilton Watch Company was one of the more notable American watch manufacturing companies, cutting their teeth on pocket watches designed and targeted at the railroad industry they developed a well known and respected business.

When World War 2 started Hamilton retooled and began creating wrist watches, effectively paving the way for the watch company we know today—That is until 1966 when Hamilton acquired Buren Watch Company which ultimately led to them moving their entire watchmaking operation overseas to Switzerland. In 1984 Hamilton was acquired by Swatch Brand, leaving us where we are today.

Hamilton still produces a wide range of high quality, Swiss made, timepieces and in this review, we are focusing on the Hamilton Khaki Field Mechanical (ref H69429931). This particular piece is modeled after their original 1969 field watch, however, the brand has modernized it to appeal to a more contemporary customer—more on that later, for now, let’s go over some specs:

• Case Width: 38.26mm
• Case Thickness: 9.95mm
• Lug to Lug: 47.21mm
• Depth Rating: 5Bar (50m)
• Weight: 2.2oz on one of my NATO straps
• Movement: ETA 2801-2
• Lug Width: 20mm

(All Measurements are my personal measurements and may differ from manufacturers specs)

Fit

There are two primary factors that I believe contribute directly to comfort when you’re looking for a watch to wear. The first is case thickness and the second is the lug-to-lug length. The Hamilton really excels in both of these areas, measuring in at less than 10mm thick (handily the thinnest watch in my collection) and around 47mm lug-to-lug it’s easy to simply forget that you’re wearing the watch at all.

One of the real benefits to having such a thin case is that when you pair the watch with a nato it still keeps the whole package incredibly thin. In terms of appearance some folks might turn their nose up at a sub-40mm cased watch, but I would challenge you to try one on if you get the chance—my wrist is around 7” and I find it very proportionate.

Movement

Ticking away inside the Field Khaki Mechanical is the ETA 2801-2. This is a hacking, manual wind, 17 jewels, movement that operates at 4Hz. In my time with the Hamilton, I’ve seen it keep really excellent time, for the price associated with the watch. This isn’t COSC certified movement, nor should it be for the $450 price tag, but it’s generally keeping within 10s/day. With its 46hr power reserve, it leaves you some margin to alternate it with another watch.

I will also point out, that while entirely subjective and not really applicable to performance; the winding action is very smooth and pleasant to use, for what its worth.

Case and Crown

I’ve already talked about its size, but I think the finishes are important on this watch, in particular. The Hamilton “GG-W-113” was originally a military field watch, issued to be worn by soldiers during the Vietnam era. The last thing that you wanted was for a shiny object on your wrist to catch the light and draw attention to you. So Hamilton solved this problem by finishing the steel case with a matte/beadblasted type finish. It looks good and accomplishes what it was meant to on this vintage reissue.

The crown is roughly a 6.5mm crown with very effective jimping around the exterior (for hand-winding). The crown does not screw down, and only have one position when you pull it out for hacking the seconds and setting the time.

Mentioning the non-screw-down crown brings up one important point to be made about this watch. The Hamilton Field Khaki mechanical is rated to 50m depth resistance, there are endless debates about how much depth resistance is “needed” for a daily wearer, I’ll let you decide that for yourself.

Dial and Crystal

In my opinion, the two things that make this watch in particular an excellent value is a. The movement and b. The sapphire crystal. There are a lot of competitive options at this price, but it will be difficult (not impossible) to find one that’s running a respected Swiss movement with a sapphire dome over it, just my .02.

Crystal aside, getting to the dial we start to really see the callbacks to the vintage Hamilton watches that inspired this one. Large Arabic numerals circle the dial in two distinct circles. The larger exterior being in the 12-hour scale, and the inner small circle being in the last half of the 24-hour scale. This allows you easily to see what time it would be in “military time,” if you will instead of having to add/subtract 12. This is all assuming you can separate AM from PM yourself.

The hands are bright white, and sort of a hybrid between sword hands and syringe hands. The bright white of the hands and hour/minute indicators really pop off of the black dial. Both hands, as well as the tip of the second hand, and triangular hour indicators are all lumed with Superluminova that’s been aged to look like an older tritium or radium dial.

Strap

The Hamilton Field Khaki Mechanical ships with a type of NATO strap that is accented with some leather embellishments. I’ll be the first to say that it looks to be a nice enough strap but didn’t fit my wrist well. I removed the OEM strap almost immediately and swapped it for a traditional camo nato I bought from natostrapco.

That’s the beauty of this watch, in particular, versatility, as I’m writing this the watch is on a Shell Cordovan Strap and looks just as at home there as it did on the NATO. It’s a common lug width, and due to the thinness of the overall package, it can wear many different straps very very well. I’ve even seen some folks source vintage styled straight end link bracelets for these watches. The options are endless, and those endless options are made easily accessible for swapping by the drilled lugs.

Hamilton Khaki Field Mechanical Review – Final Thoughts

When it’s all said and done what we’re looking at from Hamilton is their attempt to honor one of their OG models that have been a source of inspiration for watches for decades now. I believe they’ve done this successfully, primarily by modernizing it—increasing the case size to 38mm (from the original 34) and adding the sapphire over acrylic.

Field Khakis have always been good “starter watches,” and I don’t believe this one is any different, the price is a little higher than some of the other models in the line, but I believe you get what you pay for in this model even if just in terms of aesthetic. It’s easy albeit casual piece to wear, that’s at home in most normal situations. I like this watch, and it’ll be on my wrist for days to come.

It has been a good while since I last updated my personal watch journey. Some may remember that it all began with the humble Seiko SKX173. That continues to be a great dive watch that can be had for under $250. I also bought a Casio G-Shock, another excellent watch that I still own and use to this day.

Those are inexpensive watches. Nothing wrong with that, but after graduating from school and finally entering the working world, a little money began to build up. The money began to smoulder and eventually burn a huge hole in my pocket. Around that time I got the itch for a high end dive watch. After a little research, and the decision not to spend $5k+ on a Rolex, I ended up with an Omega Seamaster Planet Ocean in the older 2500 caliber movement. This was a great watch, but inexplicably after 6 months of ownership my eye began to wander.

On an impulse I picked up the Sinn U1. I bought this watch used on the forums. Frankly I should have held out for a better deal as the watch I bought was pretty beat up. But that was ultimately alright, because it turned into a daily wear for me and I have used my U1 mercilessly over the past 3 years. The first scratches are always the hardest anyways. The Planet Ocean was traded to a good friend, and the U1 hasn’t left my wrist since.

Specifications

• Case Diameter: 44m
• Lug to Lug: 22mm
• Case Thickness: 14.3mm
• Weight: 113 grams (head only)
• Movement: Sellita SW 200-1

Fit

The U1 is substantial. You will notice it on the wrist. While it’s great that this is an overbuilt watch with 1000M of water resistance, I would much prefer to see less water resistance and a thinner case. I haven’t taken the watch 1000 centimeters underwater, let 1000 alone meters, and while I’m sure some folks dive with these watches, just as many don’t.

Maybe Sinn could offer a stripped down version, in the same way Rolex has the chunky Sea Dweller Deep Sea, and then the more practical Submariner. Give it 200M of water resistance and shave a couple millimeters off the height and I’d be even happier with the U1 as a daily wearer.

As an aside, some might say I’m a poser for wearing an over built dive watch in the first place. Do you need you fly an airplane to wear a pilot’s watch? Join the infantry to wear a field watch? Straddle multiple zones to justify a GMT? Summit mount Everest to wear a Rolex Explorer? Wear a dress to wear a dress watch? Give me a break, and feel free to wear whatever watch you like.

As it stands I don’t think the watch is comically thick. It actually seems pretty balanced on my 7.25″ wrist, and it hides beneath a standard shirt cuff easily. But still, it’s a thick watch and I’d like to see a couple millimeters shaved off here. The extra bulk was never a feature for me, but I like the rest of the watch so much that I’m OK with it.

Movement

The Sinn U1 features a Sellita SW 200-1 movement. This is a competitor of the ETA 2824-2 movement. It’s a 26 jewel movement, with hours, minutes, seconds, and date, hacking, and a 38 hour power reserve.

Personally, I’ve never gotten anything close to 38 hours of power reserve out of this watch, but it keeps decent time. I end up updating the time every month or so when I notice it has gone a couple minutes fast. I haven’t bothered with testing how many seconds a day it is off. Just not something I’m interested in doing.

This is a robust movement that is shock resistant per DIN ISO 1414, and anti-magnetic per DIN 8309. Good to know.

Practically speaking I’ve put this watch through a good deal of use. Plenty of weight lifting, swimming, yard work, and whatever else for a few years now (desk riding? cheese pizza eating?). I’ll take the watch off if I’m going to dig a hole or use a hammer, but beyond that the U1 watch has been my daily watch for years. It’s taken a few hard knocks, and has plenty of dings to show for it. But it keeps on ticking.

Case and Crown

The case is a chunk of bead blasted German submarine steel. It’s simple, but crisply machined with long tapered lugs protruding out from beneath the oversized bezel. The case itself is designed to look a little thinner than it actually is, giving it a more balanced look on the wrist, but there is a lot of case here and a domed steel case back adds to the bulk.

Sinn placed the crown at 4 o’clock. This makes the watch comfortable to wear on the left hand and decreases the footprint of the watch. There are no crown guards and the signed 7mm crown is large and easy to grasp. The threading on the crown is excellent. It’s easy to unscrew the crown, wind the watch or make whatever adjustments you need to the date or time, and screw it back in place. I’m paranoid about cross threading my watch crowns, so I’m glad to report this isn’t an issue.

Dial, Bezel, and Crystal

The dial and hands of the U1 are probably the most polarizing features of the watch. You will either love or hate the “lego” hour markers and hands. I happen to love this unique look. It’s one of the reasons why I bought the watch. I must admit it was something of an acquired taste, much like Spyderco knives with their distinct thumb holes. If you absolutely can’t get over the lego hands, but otherwise like the look of this watch, then the Sinn U2 may be the way to go.

Regardless of your personal feelings towards the aesthetics of the U1’s dial, I don’t think anyone can argue how legible this layout is. The crisp red and white hands and white hour markers jump out from the jet black dial. It is a relatively simple painted dial, but in that simplicity lies an elegance all unto its own.

And of course the markers and hands have been applied with luminescent green paint. The lume is good stuff. It’s not quite Seiko caliber, but it’s pretty good and the time is easily visible at night.

Of interest is the 60 click uni-directonal bezel. It is oversized and easy to grasp. Rotating the bezel is somewhat satisfying. The clicks aren’t the crispest, but it gets the job done.

Perhaps the most interesting aspect of the bezel is that it is made from tegimented stainless steel. TEGIMENT is a special surface hardening technology Sinn employs to make the steel more scratch resistant. That’s a good thing as I’ve whacked this protruding bezel into all sorts of things. Everything from door frames to kitchen faucets. I’ve managed to introduce some small scratches to the bezel, but by and large it has held up well over the years.

Strap and Bracelet

The U1 comes with a rubber strap or stainless steel bracelet. I like the bracelet and have not worn my U1 on a strap. Part of that is because the strap I got was already cut too small for my wrist. The lugs are drilled, so if you want to swap out the bracelet for a strap, theoretically it wouldn’t be too hard to do.

The bracelet is offered in regular steel or Sinn’s tegimented steel and features the same bead blasted finish of the case. My bracelet is the regular steel, and it shows plenty of wear, but has also developed a cool worn patina at this point. It’s very difficult to see in the pictures, but up close and in person the bracelet is covered in a fine pattern of scratches and rub marks.

The edge of the clasp is worn so much it appears polished at this point. You can kind of see it in this picture (on the left side of the clasp):

Doesn’t bother me a bit.

This is a chunky H-link style bracelet with solid end links. It is easy to adjust the bracelet as the extra links are held in place with small allen bolts. While these allen bolts make it easy to add and remove links, one of the bolts wiggled loose over time and fell out. So you will want to watch the bracelet closely and periodically tighten any loose bolts or perhaps apply a little thread locker. Replacement hardware can apparently be purchased from WatchBuys.

The deployment clasp is also solid and robust. You have 3 micro adjust points on the clasp that is held in place with a pin as well as a dive suit extension. All pretty standard stuff.

I have found that the clasp itself has a tenancy to pop loose. That is probably because I wear the watch tight on my wrist. If I do something like push myself up off the floor or out of a swimming pool, the force from the contracting muscles in my forearms will be enough to pop this clasp loose. This is my biggest gripe with the watch besides the thickness of it. I’d like to see the clasp lock more securely.

Personally, I’m a big fan of the bracelet. It looks great, and I find this watch wears comfortably.

Sinn U1 Review – Final Thoughts

I love this watch. The fact that it has been my daily wear for almost 3 years and that it kicked a watch twice as expensive off my wrist should speak volumes about it. I wouldn’t call myself a true watch aficionado by any means, but I appreciate watches and could justify buying a more expensive one if I wanted to. Yet every time I stare down at my U1 it makes me wonder why I would want anything else.

My favorite part of the U1 is how it is different from everything else on the market. It seems like in the world of dive watches all roads lead back to the Rolex Submariner. That is for good reason as the Submariner is the quintessential dive watch, but what I enjoy about the U1 is that it is not trying to be a Submariner. The unique design and solid execution allow me to appreciate it for what it is. Some might want something a little sleeker and more refined, but I like it. I would like to see the case be couple millimeters thinner, and the clasp be a little more secure, but beyond that I have no complaints.

I recommend the U1 it without hesitation. In a moment of weakness, I recently purchased another dive watch (the Seiko SBDC0053). The SBDC053 is an amazing watch, and I will review it, but I have to tell you I keep coming back to this U1.

I have had a lot of fun wearing this Sinn U1, and appreciate its unique take on the otherwise ubiquitous dive watch.

Sinn has only one dealer in the states, and that’s WatchBuys. So if you want to buy one new, that’s your only option here in the USA. I don’t have an affiliate relationship with WatchBuys. I do have affiliate relationships with Amazon and Jomashop, and really appreciate the people who have used my links to buy watches and gear through those sites. When you do that BladeReviews earns a small commission that keeps the website independent, mostly ad free, and pays for our excellent writers. Thank you very much.

For some time now, I’ve been eyeing a return to the world of mechanical watches. Then, a few weeks back, Editor (and apparent mind reader) Dan contacted me with a proposition: “I bought a Seiko SNZG15J1 maybe six months ago… I see the watch every time I open up my closet and thought it might be a good fit for you.”

Ah, the Seiko 5: Darling of watch hipsters and aspiring horologists everywhere. The SNZG15J1 (I’m going to call it the SNZ going forward) is a $120 piece sitting near the top of the Seiko’s iconic value line. I’d previously owned an SNK809, and the idea of testing its premium cousin was instantly appealing. Dan was kind enough to send it over, and I spent several weeks gathering my thoughts. Here are the dimensions, to start with.

• Case Width: 42mm
• Case Thickness: 12mm
• Depth Rating: 10Bar (100m)
• Movement: Seiko 7S36C
• Lug Width: 22mm

Fit

By the time the watch reached me, Dan had already swapped the stock canvas bracelet for an aftermarket leather strap. While it looks to be about a millimeter short on each side, I appreciate the added comfort. If you haven’t experienced Seiko’s stock canvas, well, it’s not great. Those planning to buy this watch should seek out a new strap as part of the package.

Equipped with a bit of cowhide, the SNZ wears quite comfortably. The 42-milimeter case sits perfectly on my medium wrist, low and secure against the skin. The lugs curve gently around the bone, creating an effortless ride. I love the way this watch fits, which makes the next few sections all the more difficult.

Movement

Get your crosses and gear oil ready, mechanical purists, because I’m about to speak a whole bunch of sacrilege.

First, some specs. The Seiko’s 7S36C is a 23-jewel automatic movement with 41 hours of power reserve. Hacking and hand winding are absent, with an operating temperature range of 14-140 degrees Fahrenheit. I’d like to supply you with an expected accuracy range, but Seiko doesn’t include it in their operating manual.

Here’s where things fall off a cliff for me. The purpose of a watch, above all, is to keep accurate time. In my few weeks with the SNZ, I was unable to establish a consistent pattern. My Orient Mako 2, for instance, reliably runs between nine and ten seconds fast per day. Its hacking movement makes this easy to correct, so it’s not a big deal. But with the Seiko 5, I encountered variances between three and thirty seconds fast and slow. This is unacceptable in a $50 watch, let alone one costing $120. I had strong opinions on this coming off the similarly equipped SNK809, and time has done little to dull the edge. This variation is completely out of bounds, especially on a watch without a hacking second hand.

Allow me to digress for a moment. Are you familiar with the difference between polychronic and monochronic societies? In short, a monochronic civilization operates on a sense of temporal propriety. If a meeting is supposed to start at 9 AM, participants are expected to show up on time. Late arrivals and interruptions are generally considered rude unless an acceptable excuse is supplied.

In a polychronic society, however, start times are considered to be more of a suggestion. Arrivals could show up to said meeting as late as 9:30, with little to no thought given to the lapse. For those of us raised in a monochronic model, this sort of cultural divide can be a source of immense frustration.

Let’s bring this back into focus: How can Japan, a monochronic culture so hell-bent on punctuality that a 25-second early train departure necessitates an official apology, put out a movement that performs this poorly? Long story short, I’m flatly unimpressed with the operation and accuracy of the Seiko 5 series.

Case and Crown

So, it’s pretty clear where I stand on the SNZ’s functional capabilities. But what about its form? This is what I consider to be the great tragedy of the 5’s, because these watches are actually pretty well finished.

Let’s start with the case. The front side is composed of brushed stainless steel, with just the slightest breath of texturing. Things get prettier out back, with polished steel surrounding a transparent plastic window. This is the most alluring part of the watch, allowing you to see the mechanical movement in action.

The crown is small, unsigned, and basic. There’s nothing particularly memorable about it, but its action and setting is easier to access than that of the SNK809. For what it is, the setup is perfectly functional.

This case/crown combo features a water resistance rating of 100-meters. Sorry, guys, but I just don’t buy it. Take a look at this fingernail cutout tucked behind the crown:

Now look at the crown shaft, visible through the case back.

You’re telling me that this setup is supposed to ward off 10-Bar of pressure? I’m no hydrodynamics expert, but this doesn’t seem like a terribly watertight system. I’d be comfortable with handwashing and maybe a shower, but full on immersion in a lake or pool? I’d avoid it with the Seiko 5.

Dial, Bezel, and Crystal

Here we come to another SNZ strong point. The dial is clean, readable, and attractive. Its standard Arabic numerals are complemented by small 24-hour digits, with wide lume strips on the raised outer ring. A black day/date window is positioned at 3 o’clock, with a sharp white border for effect. The hour and minute hands are thick and well lumed, and even the red-tipped second hand features a touch of the glowing goop. My favorite aspect of the dial may actually be the applied “Seiko 5” badge. Its raised silver and white shapes really pop against the matte black dial, creating an appropriately sporty effect.

There’s not much to say about the bezel, beyond complimenting the subtle texture of its brushing. It sits ever-so-slightly below the top of the crystal, with just enough of a gap to accumulate debris from daily wear.

Speaking of the crystal, this is another watch utilizing Seiko’s proprietary Hardlex. It’s a material generally agreed to be on par with mineral – better than plastic or acrylic, but nowhere near the hardness of sapphire. At just over $100, I have no complaints with this choice in crystal.

Strap/Bracelet

As mentioned above, the stock Seiko canvas strap isn’t good. It’s coarse, inflexible, and generally plain. Time and wear would break it in, but just about every Seiko 5 photo on social media will include a different strap.

If you’re looking for alternative options, I’d highly recommend the folks over at Cincy Strap Works. Their NATOs generally accompany my Citizen Pro Master and Orient Mako 2.

Seiko 5 Sports Review – Final Thoughts

Last time, I opened the Casio Duro review with an ode to second sight. And it’s true – Sometimes, you don’t know what you’ve got until it’s gone. But with apologies to Cinderella and their hair-metal classic, “Now I know what I got… It’s just this overpriced, unreliable watch riding on its reputation.” I think that’s how the song went, right?

Look, I understand the mechanical appeal. The idea of a watch that’s essentially living off your body’s movement is pretty compelling. But, for around $30 more, you can get an Orient Mako or Ray II, with superior construction, accuracy, and a movement that hand-winds and hacks. Or, if you’re wedded to the field watch aesthetic, Citizen makes several excellent alternatives in this price range, such as the BM8180. Sure, they’re not filled with cool spinning gears, but their

EcoDrive movements could also be said to be “alive,” feeding off the power of the sun.

This is a watch with a huge fan base, many of whom I hold in high regard. I wanted to love it, like the cool kids do. But, if I can’t trust it to keep accurate time, then why am I even wearing it?

Proselytizing aside, only you can determine whether a Seiko 5 belongs on your wrist. I’ll admit, those looking to dip a toe into the mechanical waters could certainly do worse. But, if you dig a little deeper, I think you can definitely do better.

You know what they say about love at first sight? Well, sometimes second sight comes with the benefit of experience, once absence has worked its magic on the heart. (Re)Enter the Casio MDV106-1A “Duro,” a $44, stainless steel dive watch running on batteries and quartz. I owned and sold one of these 20bar bargains about six months ago, before purchasing a second one for the purpose of this review.

With many of the watches here on BladeReviews featuring price tags of at least three digits, the Duro’s sub-$50 cost may cause readers to overlook its incredible value and capability. This was certainly the case with me, when it left my collection after I got my hands on the Citizen Promaster Diver. But, now that I’ve handled a few higher-end pieces, the humble Casio shines all the brighter.

Enough backstory – Let’s get to the figures and review. I should note that these measurements are an amalgamation of generally-agreed-upon figures, since my tools are still packed away from my recent move. Here you go:

• Case Width: 44mm
• Case Thickness: 12mm
• Lug to Lug: 48mm
• Depth Rating: 20Bar (200m)
• Weight: 3.2oz on the rubber strap
• Movement: Casio Quartz Movement (Module 2784)
• Lug Width: 22mm

Fit

As you can see from the dimensions and comparison shots, the Duro is a rather large watch. It’s about as big as my medium-sized wrist can support without appearing to make a fashion statement. The stock rubber bracelet keeps this ticking chunk of stainless secured, and the single keeper and metal buckle operate without issue. More on the bracelet later, but it’s a solid functional design.

Here’s something to note, if you’re thinking about swapping out the stock strap: While most websites list the lug width at 20mm, I’ve found this to be closer to 22mm. So, if you’re eyeing up a NATO, be sure to buy accordingly.

Overall, the Duro wears pretty darn well. It was on my wrist for all but one day on my recent cross-country move, as well as the week of packing beforehand. Despite its size, at no point did it become a nuisance. Quite the opposite, in fact. There were many times, whether packing, driving, or moving in, when the weight of the watch on my wrist served as a welcome bit of reassurance. This sentiment held through four states worth of hotel gyms, showers, and pools.

Movement

Try as I might, I haven’t been able to dig up the exact specs for the Duro’s movement. I’m not alone in this, either – Folks like TGV from The Urban Gentry Youtube channel and other far more qualified reviewers have encountered a similar barricade. The general consensus seems to be that Casio employs one of their stock quartz movements, shown on the case back and manual as module number 2784. This crystal-controlled setup is powered by a three-year SR626SW battery, with an accuracy rating of +/-20 seconds per month.

Now, before you get too bent out of shape over that third of a minute, let me state that both of the Duros I’ve owned have come nowhere near that figure. At most, they’ve gained between one and two seconds per week. Accuracy here is on par with the Citizen and INOX, and significantly better than the mechanicals in my collection.

The Duro’s most striking feature is its second hand. Unlike many quartz pieces in this price range (I’m looking at you, Timex), its red-tipped ticker hits each of the indices with laser precision. There’s no waggle, stutter, or hesitation in its arc, which isn’t something I can say for my $250 INOX. This is excellent, and it’s been the case on both of my Duros.

Then there’s the date window. It’s nothing fancy, but visibility is decent and the changeover is solid. Setting is accomplished by pulling the crown to the first position and spinning counter-clockwise to advance the day.

Speaking of setting, I do have a minor nitpick here. Full disclosure – I’m a little obsessive-compulsive when it comes to my minute hand lining up with the markers. When the seconds hit zero, I want that long hand to be pointing dead-on at the desired minute. On some cheaper watches (or, again, the INOX), the minute hand has a tendency to jump a fraction of a millimeter when pressing the crown back into place. This creates a maddening misalignment, causing me to repeat the setting process over and over until everything lines up exactly. The Duro, unfortunately, suffers from a minor case of this hand-hopping. If you’re not a crazy person like me, this won’t be a big deal.

Case and Crown

If Casio is going to hit me with a “Pay no attention to the man behind the curtain” on their movement, then I may as well take a long, hard look at the curtain. The case housing the Duro’s internals is made of stainless steel, with a mix of brushed and polished surfaces. And while it may be rather large, it does play host to some nice details. Take the case back, for instance. Casio has clearly etched all of the relevant data (Reference number, water resistance, etc.) into the steel, with the welcome addition of their classic marlin logo. This prominent fish only appears on Casios with a rating of 20Bar or higher. It’s a pretty cool bit of badging for a timepiece costing less than $50.

The crown, like the case back, is of the screw-down variety. There are two nicely chamfered guards surrounding it, with enough slope and rounded edges to keep them from digging into the wrist. The crown itself is unbranded, with enough of a polished finish to reflect my face like a funhouse mirror. It screws into place relatively easily, though not as smoothly as my higher-priced divers. There is a bit of wiggle in its unwound state, but nothing substantial enough to cause concern.

Dial, Bezel, and Crystal

Speaking of wiggle, let’s talk about the Duro’s bezel. You’d expect a cheap diver to come with some play in its timekeeping ring, right? Well, that’s not the case here. The Duro’s 120-click, unidirectional bezel is rock solid, with a prominently lumed pip at the zero position. The canted coin edge is quite grippy, so long as your hands aren’t soaking wet.

Within the bezel lies the crystal, composed of hardened mineral glass. Not a favorite material among watch lovers, but I think Casio deserves some credit here. At $44, they could have cheapened out and gone with some form of plastic. The Duro’s large mineral crystal is perfectly serviceable for a basic beater watch, and mine picked up only a single scratch after several weeks’ worth of moving-related work.

Let’s gaze beneath the crystal, to the real appeal of the Duro. Each of its indices are applied, and the polished hands are distinct and well-wrought. This combination makes this an eminently readable watch from almost any angle, a trait that proved truly valuable on my long-haul trip. The branding is subtle and well done, with another marlin to match the one on the case back. The dial itself is something of a flat black, though there’s a bit of a sunburst if viewed from the proper angle. This deceptively simple combination lends a real pop to the hands and indices, along with the bright red of the second hand.

The most common complaint associate with the Duro lies in its lume. Here’s a comparison shot, with the $150 Citizen Promaster on the right, and the $250 Victorinox INOX on the left:

While it looks okay here, I can tell you from experience that this nigh-universal gripe is warranted. The lume begins fading almost immediately and will be all but invisible within a few minutes. The lone exception comes in the outdoors, on nights far away from the streetlight glow. You’ll be able to read it in the darkness of your tent, but it won’t be an easy affair.

Strap/Bracelet

So, the strap – Many of the big-name reviewers I’ve come across aren’t a fan of the rubber. And I’ll be honest: I didn’t give it much of a chance on the first Duro I owned. I had a BluShark NATO shipped to me as part of the package, and that’s the way I wore it. But, since the second watch arrived, I’ve worn it almost exclusively on the stock strap. Maybe if I’d done this the first time, I wouldn’t have needed to buy the watch twice.

Let me elaborate a bit here. The stock rubber isn’t great. I’ve heard Nick Shabazz describe it with words to the effect of “baby’s first watch.” And, with the higher-end stuff he generally reviews, he’s probably not too far off base. But, for whatever reason, this basic rubber bracelet just works for me. It’s comfortable, secure, easily adjustable, and (most importantly) low-profile.

Because the Duro is already a rather large watch, the addition of even a trimmed-down NATO makes it tower over the bones of my wrist. This becomes immediately inconvenient for a watch doing beater duty. It’ll snag, smack, and otherwise scratch against every tree, desktop, and doorknob in your path. Or, at least, that’s what happened to me. While the basic rubber didn’t keep the bezel from becoming close with bookshelves and moving boxes, the effect was greatly reduced from its nylon counterpart.

Casio MDV106-1A “Duro” Review – Final Thoughts

Look – This is a great watch. I’d go so far as to say that it’s the best under-$50 timepiece I’ve tested, and one of the three best under $100 (the Casio WVA-M640 and Citizen BM-8180 being the others). And on top of its aesthetic and functional merits, it’s also one of the most accessible divers on the market. Next time you’re at your local Walmart, make a quick stop at the jewelry counter. There, next to the cubic zirconia earrings and cheap wedding rings, you’ll probably find a Casio Duro.

Still, I’d recommend purchasing the watch online, as in-store prices always hover a bit higher than those in cyberspace. Whether you’re looking for a beater watch for yourself, or maybe a gift for someone who’s thinking about getting into timepieces, this is a splendid, budget-friendly choice. Take it from me, the guy who was dumb enough to sell his first one – This is a watch you’ll enjoy having in your collection.

I’ll never forget my first time walking into an Omega boutique and looking at all the shiny watches. A friend of mine, the one that initially introduced me to watches, took me there to admire his grail and ultimately discover a few of my own. Since that time I’ve had the privilege of owning and wearing several Omega watches and my buddy has attained (and daily wears) his grail Planet Ocean. In fact, my first ever “nice,” watch was an Omega Seamaster GMT 2534.50 that I wore for a long time, but ultimately sold for reasons that escape me now.

Buy the Omega Seamaster 300M Ceramic at Jomashop

Since then I’ve owned several versions of the classic wave dial Seamaster, numerous variations of the Speedmaster, and even a Planet Ocean but all of this to say… For some reason, I am drawn back to Omega, like a moth to the flame… That brings me to my most recent acquisition, the Omega Seamaster Diver 300 Ceramic. The most modern iteration of the Seamaster Professional series (although soon to be ousted by the new—new wave dial coming from Basel this last March). Before we get too far, let’s go over some specs:

(All Measurements are my personal measurements and may differ from manufacturers specs)

• Case Width: 41.5mm
• Case Thickness: 13.1mm
• Lug to Lug: 47.3mm
• Depth Rating: 30Bar (300m)
• Weight: 5.9oz on the bracelet
• Movement: Omega 2500D Co-Axial Movement
• Lug Width: 20mm

Fit

There are some watches that really feel like the manufacture nailed some sort of “golden-mean-symmetry” balance and created a watch that just works on the wrist. Other’s work fine, but have some minor comfort issues that you have to overlook like, the crown digging into your hand, or the lugs being overly long and overhanging your wrist… but the SMPc hits those special measurements.

This watch is a dream to wear, with lugs that gently drape over your wrist and a thickness that keeps the watch from getting in the way of your day to day life. I think this is what keeps pulling me back to the SMP series—they really are a joy on the wrist.

Movement

The Omega 2500 Co-Axial movement has been around since 1999 and was Omega’s first wide-scale implementation of using Co-Axial movements in their watches. The 2500 is also not without its flaws and issues. There are five generations of the 2500 starting with the 2500 itself and then progressing to the 2500A, B, C, and finally D.

Some of these earlier movements suffered from some rather serious performance issues. Instead of chronicling all the reporting that has been done on the generations of the 2500 movement, and opinions that have been spread around about whether the C generation is reliable, or if the D is the only one to buy, I’ll say this: I’ve owned a couple watches with movements that were derived from the same 2-level coaxial technology. One of them was an early on Co-Axial Speedmaster that DID have issues and needed to be serviced. All of the rest have been perfectly fine.

In addition to this, the SMPc’s were released after the 2500D movements were released, and they all feature the new, reliable design of this Co-Axial movement. So strictly speaking if you buy the newest ceramic bezeled version of the Co-Axial Seamaster, you’re getting the latest version of the movement, and there’s nothing to worry about. In addition to that, I can say that my watch is keeping phenomenal time, gaining roughly 1.5s/day. Hard to beat that.

Case and Crown

The SMPc’s case is pretty straightforward with nice brushing along the sides, and polished twisted bevels on the lugs. The thinness of this case is pretty remarkable, and as I said in the fit section above, really makes this watch a joy to wear. The case-back is also pretty good lookin’ featuring Omega’s trademark Hippocampus and the laser etched Omega logo along the side.

As for the crown, the Seamaster has two, one primary crown at 3 o’clock that you’d expect, and the one for the Helium Escape Valve at 10 o’clock. The crown is signed with an Omega logo and nicely textured to good grip when loosening it screwing down. The crown guards on these Omegas have always struck me as pretty interesting. They almost appear to rise off the side of the watch and gently hug the crown. There’s not much to say about the HEV crown at 10, except that you’ll never use it unless you want to fidget with something, and some people get some real heartburn over it being there at all. I’ll let you decide for yourself.

Dial, Bezel, and Crystal

As always, top-down: The domed sapphire crystal is very well executed on this watch. Omega does a great job with the AR coatings, and in the right light, it can look almost as if the crystal isn’t there. Also, while it is domed, it doesn’t stick up so much that it will be a “snag-hazard,” there’s nothing that’s gonna protrude on this watch.

The bezel is where the modernity of the new SMPc’s starts to show itself. As the “c” would suggest in the name, these bezels are ceramic with a sort of matte grey numeral all the way around. There is also a lume pip at the 60-min mark that generally sits at noon. This bezel looks gooooood. The ceramic matches the deep blue (or black if that’s your style) of the dial perfectly and shows a ton of complexity as the light plays across it. It’s also a 120-click rotating bezel that’s a joy to actuate, snapping into each half-minute position with positive authority. While I would have loved to see some additional lume on the bezel like the Pelagos has, it would largely be vestigial and I am pleased as-is.

And the dial; as you look at the watch you’ll begin to see some subtle changes from the older non-ceramic Seamasters, and really, you should as there are nearly 20-years that separate the designs. The hour indices are applied with beautifully polished (I assume) steel surrounds, filled to the brim with lume. The Omega logo just under the noon-double-indices is applied and polished, as is the “Omega” beneath that. The depth of the dial’s color is also quite something to behold as well. I’ve always liked the wave dials, but the deep glossy blue dial is superb.

The lume itself is worth remarking on, Omega always does a good job on lume. On the SMPc they’ve mixed lume colors, with the primary color being blue on the hour hand, and indices, but the minute hand and diving bezel pip’s lume is green. A cool touch if you ask me.

I wanted to specifically address the hands on this watch. The skeleton hands have been a hang-up for me, and probably been the biggest reason I’ve avoided buying this watch for years. I still do not like the skeleton hands from the older wave dialed versions of the SMP, but the newly updated handset on the SMPc are excellent. Polished, with amply applied lume they catch the light in the same way as the applied indices and Omega script/logo. All this to say, the SMPc has converted me to the skele-hands, at least somewhat.

Strap/Bracelet

Omega’s bracelets have always been excellent. They articulate nicely and drape well over the wrist. This bracelet is no different. It’s slightly dressier than the “Speedy Bracelet” the Speedmaster or 2254.50 comes on, but the varying brushed and polished surfaces are nice. Omega has also moved away from pin/collar construction for screw links. That’s always good. This watch will also be amazing with a NATO strap if you want to trend a bit more on the casual. side.

Omega Seamaster Diver 300M Ceramic Review – Final Thoughts

So, all of this to say, I am extremely impressed by the Omega Seamster 300M in Ceramic. Omega always does a good job, but it’s easy to see here why this model has remained a classic and has also remained largely unchanged in design for years. Omega has made some small improvements with each iteration, but no drastic changes. That being said, it’s worth looking into the newer version coming out later this year (2018) to see if perhaps you want to wait for that instead of grabbing one of these right now. Either way, you’re going to wind up with a watch that will serve you for years to come.
