Sinn 8820T

Overview

The 39mm Sinn 8820T comes in three different dial variants. Plain sterile dial, yellow U-Boat dial and red U-Boat dial. Unconfirmed information says that the U-boat dials were limited to 200 watches each and only for the Asian markets and the sterile dials were distributed globally.

Basic information

The 8820T is special, because it is Sinn’s first full titanium watch and features a capillary depth gauge. The watch is also interesting, because it doesn’t have direct Heuer cousin reference like many other Sinn 80s dive watches.

My interest in the Sinn 8820T came after realising that Sinn 8820T has nearly everything the brands new lineup has. In a way 8820T is very similar to T2, but the watch also resembles Sinn’s other dive watches such as the U1/U50.

8820T, 801A, 805 and 809 aut

Despite being Sinn’s first titanium watch, the 8820T is only one of many Sinn’s 80s dive watches along with 801A, 805 and 809 aut. The 801A shares a case with Heuer 980.023 Deep Dive / Spirotechnique watches and comes with impressive 100ATM depth rating.

On the other hand, the 805 is built into a classic Monnin case and the 809 shares genes with Heuer 980.004. While the 801, 805 and 809 were both offered with automatic and quartz movements, it appears that 8820T was only available with an automatic movement. Without confirmation from Sinn, it is only possible to speculate the years the watches were produced.

The Case

The case of the 8820T is 39mm side-to-side, 43mm from lug-to-lug and 11mm thick. The size alone makes the watch invisible on the wrist. Combined with its titanium construction, the watch is both light and slim and wears extremely well on a nato strap. Like the 805 and 801, the 8820T is built into an outsourced case produced by MRP SA.

The Bezel

The bezel is machined into the case to protect it from accidental adjustment. To turn the bezel, user has to grip the bezel from sides and twist. The bezel has a painted tritium triangle at twelve o’clock position that can wear off. The numbers on the bezel are painted as well, making them subject to wear over time. The bezel action is sufficiently toolish and resembles Heuer references of the same era.

The Bracelet

The bracelet of the Sinn 8820T is made by the legendary Novavit SA (NSA). The bracelet itself is made out of folded titanium and resembles modern Sinn H-link bracelets, but rattles wiggles like a true vintage bracelet. The special feature of the bracelet is the patented NSA spring-loaded divers extension on the clasp. The NSA bracelets with this clasp offer instant micro-adjustment by spring-loaded pulling and recessing automatically. Unfortunately, this mechanism is subject to failure over time due to fatigue of the spring.

The NSA bracelet is a rare part and could be made out of unobtanium and thus it is very difficulty to source one. However, the bracelet is shared by Sinn 8827 and Sinn 8826. The end-links for these watches are different as the 8820 takes in less curving end-link, whereas the Sinn 8826 and Sinn 8827 have more curvature in the end-link. If you have the correct end-links, but a short bracelet, you can try to look for extension links (or message me because I have some and an extra clasp) or cannibalise a watch for its bracelet.

Serviceability

I queried about the service of the bracelet and the watch directly from Sinn. It looks like Sinn doesn’t have the crystals in stock anymore and water resistance cannot be guaranteed. Likewise, Sinn doesn’t have bracelets or their extension links for the NSA style bracelets. Communication from Sinn was good and exact, and they explained carefully what they will do to the watch. The final price of the service was aligned with the quote.

The service price list on Sinn site is reasonable. However, you will need to factor in shipping the watch. When serviced by Sinn, the service price is in the ballpark of 200-400 euros. The final price for my Sinn 8820T was 350€ including shipping costs. This included new crown, clasp spring and movement service. The service took over four months, but it is hard to make judgement here as I had a Sinn 156 sent there simultaneously.

Conclusion

Sinn 8820T can be considered a grandparent of Sinn T2 and perhaps even Sinn U50. The watch has a very distinctive look with its NSA bracelet. The watch is light and only 11mm thick making it virtually unnoticeable when worn. Due to the thinness, the watch wears well worn on a NATO although you may have problems fitting some of the thicker NATO straps due to the lug and spring-bar positioning.

The tritium compound on the dial and hands seem to age evenly, and makes a very pretty patina over time. This can be seen in many examples photographed online. The only downside is that the lug to lug of the watch is short, so it wears relatively small to those who have the big watch kink.

Fortis Easy Math Ref. 7242

Overview

Fortis Easy Math is a quirky 70s watch to the bone. The watch has a cushion case, two crowns and a busy dial. The dial has tritium plots, beautiful deep blue color, elevated disc with compass cardinal directions and a rotating slide rule bezel.

ManufacturerFortis
Reference7242
MovementFHF-ST96
Diameter37mm
Thickness12mm
Lug to lug44mm
Lug width20mm
MaterialStainless Steel
Water Resistance5 ATM
Basic information

The stainless steel case has a beautifully sunburst finish with radially brushed surfaces and polished sides. A similar radial finish was used at the time by Omega in their various references among many others. The watch may look like a dive watch, but it is not and has a very modest depth rating.

The Dial and the Bezel

The most interesting aspect of this watch is the dial and the bezel. The bezel can be used perform multiplication and division operations by using the slide rule (and hence the name ‘Easy Math’). There is a lot of information online how to use the slide rule and how to use watch as a compass, so I will omit those.

The Case

The 37mm case is often advertised as 38mm by over eager sales guys to serve the big watch fetish. The case features two crowns, and is thus typically labeled incorrectly as EPSA super compressor. The EPSA super compressors feature a dive helmet and other EPSA markings on the case-back, but the EasyMath is missing those.

Example of EPSA Markings

The upper crown manipulates the internal slide rule bezel. and the lower crown winds the movement and sets time. The internal gear of the slide rule bezel crown is plastic. The same applies to the teeth on the bezel disk. When encountering mechanical resistance, one should probably avoid adjusting. Turning the bezel risks damaging the gear or the teeth. Replacement parts are unavailable.

The Movement

The manual FHF-ST96 movement is not particularly well regarded, but it is sometimes called workhorse movement. It operates at frequency of 18000A/h and has a power reserve of 48h. While it lacks many nice modern features, the only thing it left me yearning for is hack seconds.

The winding experience of the movement is smooth and the hands move precisely when time is set. While the FHF-ST96 is found in many fake / franken watches, I haven’t noticed that the Easymath is being faked. This would be unlikely due to the lack of market for the watches, but it would be a mistake to assume that something is too cheap to fake.

Conclusion

The unusual dial alone makes Fortis Easy Math worth collector’s interest. The movement is not haute horlogerie, but it gets the job done and at least feels nice to wind. Despite the modest technical properties and lack of complications, the watch feels excellent on wrist, looks great on a variety of straps and above all, you can find one for cheap. In the end, what more can you ask for?

Blushark Knitweave Review

ollipekkaLeave a comment

The Blushark Orca is one of the best NATO straps I have had and I reviewed it very positively here. Based on the Blushark Orca, I had very high hopes for the Blushark Knitweave. The Blushark Knitweave straps come with either 20mm and 22mm width and are supplied with brushed hardware. The straps come in well known colors such as navy, khaki, green and black along with color combinations with highlight line.

The Blushark Knitweave straps are great on paper. They are keeperless, thin and seem perfect for a tool watch. However, in practice, the results are lukewarm at best. The strap could be slightly thicker, less glossy and slightly coarser and they would work much better for toolwatches. Due to the glossiness, the colors of the strap are slightly off. The khaki is too light and the army green is a little too deep. Consequently, the Knitweave straps sit somewhere between seatbelt-style and standard nato straps.

A word of warning: for flat watches where there isn’t much angle between the spring bars and the case back, the straps are somewhat dangerous due to the slickness. I nearly dropped my Tag Heuer 180.023 while taking the watch off, because the watch slid off the strap. The strap is also thin enough to justify a keeper. The straps are definitely for enthusiasts who enjoy thin straps.

This is my blushark knit weave natostrap mini review: I really like the style and the texture, but I am somewhat put off by the thinness. The strap isn’t quite like the Tudor straps despite similar appearance and I would have preferred a keeper for extra security especially since the strap is so slick. The colors are OK and could have been a bit better. Khaki is too light, green is kind of off, but the blue is very good. The strap is comfortable, but nothing special. Would I order more? Not unless a very nice color shows up. The strap might work for someone who is looking for a thin strap with knit pattern. I still prefer the blushark orca strap over these, but I tend to prefer more rugged straps. #blushark #natostrap #watchstrap #watches #blusharkorca #blusharkstraps #watchreview #watchesofinstagram #heuer #tagheuer #heuerdiver #tudor #vintagediver #watchfam

I was initially hoping for a cheaper alternative to a Tudor-style nato strap, but I had hard time matching the straps with the watches in my collection. I can see that these straps could work with watches with colorful dials withand polished surfaces. Because of OK, but not great wrist comfort, the glossy texture and color and slickness, I have hard time seeing these becoming permanent choice for any of my watches. For people who enjoy thin seat-belt-style fabric straps, the Knitweave can be a welcome addition.

Sinn 158 on a bracelet

ollipekkaLeave a comment

History

Sinn has made multiple successors to the 1550 sg produced by Heuer and Sinn. The Sinn 1550sg was directly succeeded by Sinn 156 and Sinn 156b and then followed by Sinn 155 and Sinn 158. Whereas the Sinn 155 is more true to the 1550 sg, the Sinn 158 sits somewhere between 1550 sg and 156b.

The elephant in the room is that neither Sinn 158 or Sinn 155 Darkstar was sold on steel bracelet whereas with Sinn 156 the bracelet was always an option. This leaves many Darkstar and Sinn 158 owners yearning for that cold hard steel on their wrists. The situation is bad, but it is not intolerable. Before the Darkstar and the Sinn 158, Sinn produced various watches with the reference Sinn 155. One of the came with steel bracelet.

First of the series is Sinn 155 ‘Manufactum’ with Valjoux 7750 movement. This was limited edition of 272 to the German market, sold via Manufactum. This watch features day/date chronograph seconds, minute register at top and hour register in bottom. I haven’t personally handled this watch, so I don’t know what the case is like. However, judging from pictures this is where the series begins.

The second entry to the series is Sinn 155 ‘Replica’, again a 300 piece limited edition made only for the Japanese market. The bracelet was optional for these watches. This watch features classic two register layout with minutes on the right and seconds on the left. Unlike the other versions, this watch uses manual wind movement. Judging from the packaging of the bracelet, the bracelet was supplied separately.

Middle Sinn 155 ‘Replica’, Right Sinn 155 ‘Manufactum’

Finally, the third iteration before 158 is the Sinn 155 Darkstar collaboration with The Rake and Revolution magazine. Owners of these watches are in similar position as owners of Sinn 158. The Darkstar is very similar to the Sinn 155 ‘Replica’, but has automatic SW510 movement. Additionally, the Darkstar features a black star on the dial and faux lume, which makes it very attractive to those who want a modern equivalent to the Sinn 1550sg.

The Solution

The cases of Sinn 155/158 and Sinn 156b are not identical, so it is unlikely that the SEL bracelet of Sinn 156b will fit. The hollow end-link bracelet might, but until I have access to one, this remains to be a mystery. The solution for owners of the Sinn 155 Darkstar and the Sinn 158 is to acquire a bracelet for the Sinn 155 Replica. The cases of all these models seem to be identical.

In conclusion, the solution is not without problems. These bracelets are rarer than either Sinn 155 Darkstar or Sinn 158. However, they are a perfect fit. Those bothered by the Sinn 155 text on the bracelet can swap any bead-blasted Sinn clasp and have their nightly sleep. The end result is great and completes the watch.

Tag Heuer 980.023 / 180.023 / 180.123 Review

ollipekkaLeave a comment

Heuer (subsequently Tag Heuer) made some amazing dive watches. This review focuses on the dive watch which was in production for nearly 20 years in different variations and is known as ‘Deep Dive’ or ‘Spirotechnique’. This is certainly not the first post about this topic and definitely not the last.

Diameter42mm
Lug to lug46mm
Lug width20mm
MaterialStainless Steel
Basic information

The watch comes either automatic or quartz, with depth rating of 1000m or 200m and under various brand names. The distinctive features of the watch are its large bezel and crown at 4’o’clock.

The most famous incarnation of the watch is the variant known as ‘Spirotechnique’. This is a watch initially produced by Tag Heuer and later produced by Auricoste for the diving equipment company La Spirotechnique. This watch was issued to Marine Nationale combat divers and the issued watches are the most sought after pieces especially if they come with provenance such as decomissioning paperwork.

The other pieces don’t share the same fame, but have other merits. The other variants come either Tag Heuer or Heuer branded. ‘Deep Dive’ variant 980.023 boasts depth rating up to 1000m. The automatic version 180.023 has depth rating of only 200m can also have the Spirotechnique logo on dial. The ‘Nightdiver’, or reference 180.123 has full tritium dial, but is otherwise the same as the 200m automatic.

Various references

The Dial

The dials of the different watches are nearly identical. They differ in branding, movement and whether it was produced for La Spirotechnique or not. The Deep Dive dial has a crystal retaining ring and extra gaskets which explains the extra depth rating.

All of the dials have tritium hands and indexes and no radium or luminova variants exist. I haven’t owned or handled the Heuer variant, but I wouldn’t hesitate adding one to my collection if one showed up.

The Movement

The ref 180.023 & 180.123 automatic versions use ETA2824, which is offers no surprises either positively or negatively.

The older Heuer branded quartz versions (980.023) use ESA movement, which can be difficult to source parts for in case of movement failure. However, the newer Tage Heuer branded ETA variants are replaceable quite easily and there are no worries from the maintenance perspective.

The Case

The case has uniformly polished finish and there is no play between polished / brushed surfaces. The bezel is a dominating feature of the watch as it is both big and tall. Despite of the polished surfaces, the watch pulls off that rugged tool-watch appearance that is very popular among vintage collectors today.

In spite of the relatively modern (read large) size, the watch wears comfortably. This is due to moderate lug to lug and low 12mm profile. My personal preference is a tall case back that extends bellow lugs and the non-Heuer variants lack this feature. However, it wears exceptionally well on nearly any strap or bracelet.

The edges of the lugs aren’t particularly defined, and the case is vulnerable to extensive polish. The crown side has two distinct surfaces and over polished cases typically loose the definition here. Same applies to the lugs, which also should have two distinctive edges diving the lug. On badly polished examples the lugs are nearly round and the definition is lost.

Polished case

Finally, the various references seem to have come with different crowns. Some of the 980.023N and 980.023L seem to have a smaller Tag branded crown whereas the crowns on the automatics seem to be larger. It may also be the watches I have handled have had service or aftermarket crowns.

The Bracelet

The standard bracelet to the watch is your typical Heuer / Tag Heuer diver jubilee with hollow end links. It is a comfortable bracelet, made out of good steel and a good companion to the watch. It is relatively hard to find these bracelets or extra links to them. Collectors looking to add add the bracelet to a rogue watch-head should be prepared to spend a pretty penny and significant amount of time on auction sites.

This is not going to be a popular opinion: the bracelet is is nothing special, and similar quality jubilee bracelets can be easily acquired if one suffers from the steel bracelet fetish and does not care about the originality. The bracelet is flimsy and rattly, but not in the good Rolex five-digit way. Both the deep dive and the Nightdiver are extremely versatile on a Nato strap and not being able to find a watch on the bracelet shouldn’t force anyone to skip the watch.

Conclusion

The Tag Heuer ‘Deep Dive’ or ‘Spirotechnique’ is a watch that works well on a nato strap. It is a versatile watch with very utilitarian look. It is susceptible to excessive polishing, but its maintainability is relatively good due to aftermarket parts producers such as tag1000diver. Even the ESA quartzes can be converted to more modern movements with some difficulty. As such, it is a vintage watch that can be worn, even heavily, which cannot be said from all vintage watches.

Blushark Orca Review

ollipekka1 Comment

Introduction

In the past few years, we have seen the introduction a few new Nato strap styles such as Tudor knit straps, Omega seatbelt straps, Marine Nationale stretch straps and perlon straps. Compared to a standard Canvas NATO strap, these new strap styles are a little different and aim to provide better comfort, slimmer profile, better adjustment and more colours and textures.

Omega and Tudor straps are also quite expensive. The general sentiment is that these straps are high quality and built by manufacturers with access to manufacturing facilities and materials unavailable to smalltime producers. However, one might think there is only so much you can do with a fabric and there must be a point of diminishing returns somewhere.

In simplest terms, Nato strap is a piece of cloth that is used to tie a wrist watch to your wrist. The point of the whole thing is that a Nato strap is cheap and disposable, and once the strap is worn out, you chuck it and buy another. Things I expect from a Nato strap:

  • Strong
  • Cheap
  • Not made out of too fancy or weak material
  • Lasts a long time.
  • Fabric doesn’t undo.
  • Steel hardware.
  • Looks good.
  • Enough colours.

Blushark Orca

Blushark Orca is a heavy-duty strap. Its distinctive feature is the waffle weave that sets it apart from basic canvas straps. The strap is thick, so you don’t perhaps want to wear your 1,7cm thick Planet Ocean GMT on one. However, for the thickness, you get excellent looks and a thick durable strap that seems like it’ll last a lifetime.

I’ve worn my Seiko Turtle SRP777 on one, and it works just fine. While the SRP777 is not particularly high, its still 14mm. For smaller watches such as skin divers and military watches the strap is perfect. It wears comfortably and the extra thickness doesn’t bother at all. The waffle pattern is different enough and the conservative colors create a very desirable rugged look.

Colors

The available colors are fairly limited, but yet enough. Colors that particularly work well with the Orca waffle strap are: army green, khaki, navy blue and gray. In addition to these the strap is available in the both standard ‘Bond’ colors, but I don’t participate in secret agent LARPs so I never wear those.

Three Orcas and two Phoenix Natos

In addition to the standard conservative colors of Blushark also offers some brighter colors. Of these, my favourite is the gray and orange and bright orange. The gray and orange works exceptionally well with titanium / bead blasted finishes. A colour that is on my wish list is burgundy or wine red. I’d definitely wear it with my watches with red details such as red seconds hand or red text.

Price & Packaging

Individually, the price of the Blushark straps is somewhat steep at 19 USD (checked in August 2020). However, Blushark runs ‘buy 2 get 1’ and ‘buy 3 get 5’ offers, which radically change the value proposition. This coupled with free shipping and -20% after a special offer such as holiday or sale and you have nearly unbeatable price per strap a little over 10 USD a piece.

The single biggest disappointment with the Blusharp Orca strap is the packaging. Each strap comes individually packaged in a plastic foil. This is quite literally, total waste. The strap could come either in thin paper or — surprise surprise: no packaging at all. This may be difficult to implement as obsessed strap enthusiasts will return the products when encountering the slightest scuff on the hardware.

Conclusion

Whereas the recent trend has been copying Omega and Tudor straps, the waffle weave Orca is a reminder what a strap should be. With the price of single Omega strap, you can buy 20 Blushark straps. Blushark offers a serious good looking Nato strap for a decent price that definitely works well with tool watches.

Omega Planet Ocean cal. 2500, 42mm

ollipekkaLeave a comment

Overview

Omega Planet Ocean (PO) line was introduced in 2005. The watches come in both 45mm and 42mm size and are famous for being worn by Special Agent James Bond played by Daniel Craig. In Casino Royale, Daniel Craig wore the 45mm planet ocean on rubber strap and in Quantum of Solace the 42mm 2201.50 on steel bracelet.

ManufacturerOmega
Reference2201.50
Movement2500 (ETA 2892-A2)
Diameter42mm
Thickness14,5mm
Lug to lug46mm
Lug width20mm
MaterialStainless Steel
Water Resistance600m
Basic information

The design of the PO draws from the history of the Omega Seamaster. The PO has a two part bezel found in pre-bond Seamasters and some of the earlier Omega references. The source of the bezel design is most likely Omega Seamaster 300 ref CK2913 produced in late 1950s. Another historic design choice is the curved lugs, which omega have been using since the appearance of first ST Speedmasters.

Various References

One thing worth mentioning is that the cal 2500 Planet Ocean has sharper case than the 2531.80 or 2254.50 Seamasters. While the lugs on the 2254.50 are similar, the form is considerably softer than on the Planet Ocean. This creates an impression of quality of the finish and a more modern look. I haven’t handled a modern unpolished Speedmaster myself, but it is said that modern Speedmasters have similar quality to the lugs.

It may be that all of the 2531.80s and 2254.50s that I have handled have been polished, but at this point, it would be extremely bad luck. Until otherwise proves, I’m going to assume that the edges on the older SM300 lyre lugs weren’t as sharp as on the PO lyre lugs.

Because of the many different color combinations, strap options and sizes, the following table attempts to summarise the reference numbers for 42mm Planet Oceans:

ReferenceStrapBezel colorIndex Color

2209.50BraceletOrangeOrange
2909.50.91RubberOrangeOrange
2909.50.38LeatherOrangeOrange
42mm Planet Ocean References

The sheer number of available references may make finding the right watch to purchase difficult. However, it is a good idea to extend one’s searches as deals can be had in any of the references. Unfortunately sometimes dodgy sellers downplay the size and offer 45mm references as 42mm and this creates further confusion.

Bracelet vs Strap

As outlined earlier, the PO came in at least four different strap configurations: steel bracelet, steel mesh, stitched rubber and rubber. I have had pleasure to handle the non-sticthed rubber, and it is easily one of the best rubber straps I have had. It is both comfortable, doesn’t have the groce vanilla smell, which connoisseurs of poverty-grade rubber straps claim to be characteristic of nice vulcanised rubber. The strap doesn’t cause itch even when worn extensively.

The bracelet for the cal 2500 Omegas is 1580 / 952. Unfortunately, my watch never came with bracelet, so until I can source one second hand, I’m unable to review it. I know that the bracelet came with both pins and screws. As with 2254.50, a popular modification is to add micro adjustment clasp to the bracelet. More of this including the parts numbers can be found in the 2254.50 article.

1589/858Steel bracelet from cal 8500

98000364Rubber strap from cal 8500
Available bracelets for cal 2500

The 1589/858 sits slightly too thick on the watch, but many prefer it because of availability and better clasp. The incorrect size of the 858 end link is especially noticeable where lyre lug meets the end-link itself. The rubber strap also 98000364 extends slightly above the lugs, but it is barely noticeable.

In addition to the steel bracelet and the rubber straps, the cal 2500 Planet Ocean wears well on a shark mesh. This is one of my personal favourites because the mesh is light and comfortable.

Hand Winding

The hand-winding experience of the cal 2500c is very nice and smooth. Unlike the 1120 or the Rolex Calibers, you can only hear a very faint sound of turning gears when hand-winding. In many watches, I would associate this winding to the wrong direction. Once wound full, just like the 1120, the movement gives nice pleasurable clicks to tell the winder to do something more productive with their life.

2500c vs 2500d

Anyone who is looking to buy any cal 2500 Omega watch is bound to find a lot of discussion over the differences of the movement. The differences have been discussed extensively. In short, the 2500d comes with three-tier escapement as opposed to the two-tier escapement of the 2500c. It is said online that the advantage of this is that the service interval of the 2500d is longer and the 2500d movement is less subject to failure due to wear or dislocation of the part.

Conclusion

The biggest misconception regarding the Planet Ocean 42mm is that it is a big watch. This is most likely caused by its 45mm cousin, or the newer 43,5mm versions. The 42mm PO wears slightly smaller than the flatter 2254.50 despite being taller. It also wears considerably smaller than Seiko MM300, which feels like a chunk of steel strapped to your wrist. On my 16,5cm wrist, the watch feels perfectly balanced on the rubber strap.

The various PO strap options, the two different movement types and the three different bezels/dials configurations can make the purchase confusing and somewhat difficult. Beyond the various references, the watch has a lot to offer: not many watches are simultaneously conservative (2201.50), playful (2201.51) and slightly obnoxious (2209.51).

Fake Vietnam / Military Watch

ollipekkaLeave a comment

There is a well known fake vintage watch that is persistently used to con newbies into thinking they have hit the jackpot. The dead giveaway is the reference Y22668 and the number 10589463. If you find this blog post by googling those numbers, the watch in question is a fake. None of these watches are authentic or contain a single original part.

Fake Omega

Conclusion

There is a slim possibility that a legit vintage military watch exists somewhere with Y22668 and 10589463 stamped on the back. However, if Google brings you here with these numbers, the watch is most likely a fake. The brands are at least Patek Philippe, Rolex, IWC, Omega, Tudor and Breitling.

Interestingly there are few variations of the Rolex with seemingly random numbers. It may be that in later evolutions the manufacturer has switched to random numbering so that the watches aren’t easy to find by Google in blog posts such as this

Overview

This is a review about the Omega Seamaster 300 2254.50. The watch was sold along the ‘Bond’ Seamaster 2531.80 and its differences to the 2531.80 are sword hands, indices, bracelet, colors and big triangle dial. The “big triangle” on the dial along with the rectangular indices are a throwback to the classic 166.024 and 165.024 Seamasters.

However, to keep Omega references complex, Omega released a few other similar, but different models, such as the 2255.80 electric blue and steel, 2533.50 America’s cup with black dial and steel and the 2054.50 which nearly identical to the 2254.50, but mounted on the 5-link Bond bracelet.

Hand-winding Experience

The Omega cal 1120 derived from ETA 2824-2 is a workhorse and can be enjoyed for its utilitarian aspects. It is neither pretty or advanced, but it does the job.

The hand-winding experience of the 2254.50 is close to standard ETA 2824-2. There is really nothing new to anyone who has handled an ETA 2824-2. While the winding experience is relatively far away from the modern luxury watches, the watch gives satisfiable clicks to notify when it has been fully wound.

Nato Strap

The 1610/930 bracelet of the 2254.50, even with its modest taper, may not be for everyone. For a person with a smaller wrist, it can fear bulky and cumbersome. The 2254.50 is a relatively thin watch. Because of its 11mm thickness, it wears perfectly on a nato strap. With a slim 1mm thick nato strap the watch wears only 14mm on a nato strap with a keeper. This is still 0.5mm thinner than a Planet Ocean cal 2500.

Due to the thinness of 2254.50 it is possible to use some of the thicker Nato straps with Keepers, such as Blushark Orca. Even with a 1,5mm thick waffle weave Orca, the 2254.50 is at 14mm of thickness. This is still 1,5mm thinner than a cal 8500 PO.

My preference is to wear it on a Nato strap over the excellent Speedmaster-style bracelet. Luckily, most watches come with the bracelet, so you can decide for yourself.

Mods and part numbers

Non-America’s Cup Dial: In this mod, the dial of the 2254.50 is changed to the Non-America’s Cup Dial. In this dial the indices and Omega text are applied vs painted / printed.

Planet Ocean Seconds Hand: In this mod the second hand is changed to PO seconds hand which some think fits better the sword hands. Also the tip of the seconds hand is brighter.

Micro-adjustable clasp: In this mod the normal clasp is changed to the more modern micro-adjustable clasp. This requires changing the last links to ones with screw ends. This gives the wearer three different positions to adjust the watch thorough the day.

Conclusion

The 2254.50 is a great watch. The bezel of the 2254.50 is a letdown, but the size, lume and dial make up for its downfalls. The watch is simply great and works well with bracelet and even better on a Nato strap.
