Bulova s MIL-SHIPS Went from Jun 7, 2025

How Bulova’s MIL-SHIPS Went from Top Secret to Top Shelf

In the world of military-issued watches, some models are legendary. Others are ghost stories-rare prototypes whispered about among collectors, their existence confirmed only through archival fragments or the occasional sighting in the wild. The Bulova MIL-SHIPS-W-2181 falls somewhere between the two, and for the first time in decades, one of the few surviving examples is surfacing in public-on the block at Sotheby’s, no less. A Mission-Critical Beginning To understand why this watch matters, you need to rewind to 1955. Amid Cold War tensions and escalating naval operations, the U.S. Navy sought a robust dive watch for its elite underwater teams-specifically, the Underwater Demolition Teams (UDT) and Explosive Ordnance Disposal (EOD) units, the forebears of modern Navy SEALs. The specifications they drafted, known as MIL-SHIPS-W-2181, called for something no commercial watch at the time quite delivered: water resistance beyond 400 feet, excellent night visibility, a highly legible dial, and a locking, unidirectional bezel. The post How Bulova’s MIL-SHIPS Went from Top Secret to Top Shelf appeared first on Worn & Wound.

Hands-On: the Trafford Watch Co. Daytripper Worn & Wound
Grand Seiko 9F models but all Jun 3, 2025

Hands-On: the Trafford Watch Co. Daytripper

I have the unfortunate obligation to begin this review with a shocking admission: Zach Kazan was right. Some time ago, during one of my back-to-back travel periods where I jumped through time zones, I had a spirited debate with our Managing Editor. I maintained that I not only enjoyed having a GMT, but needed one to keep my timing straight; while Zach insisted that I was wrong. In the past, a traveller’s GMT had been an invaluable tool in the workplace, keeping me mindful of editors working in other time zones. Yet, Zach argued that all you needed was an independently adjustable hour hand and some basic math skills. If you are working across time zones, do the math. If you are traveling through them, change the hour without messing with minutes and seconds. Immediately upon landing back in New York from a trip to London, I started looking for an Omega Aqua Terra.  During my search, it struck me as odd that this jumping hours complication (without an associated GMT) was not more widely seen, and never really on the more attainable side of things. Sure, you can find it in models from Omega, parts of Citizen’s The Citizen collection, the Ming 17.09, and newer Grand Seiko 9F models; but all of those will set you back a few thousand dollars. That is, until now. As if from some stroke of divine intervention, I received word of a new watch coming from Trafford Watch Co., utilizing a clever movement alteration to achieve this complication at a much more attainable price point...

Cartier Tank Louis Review Teddy Baldassarre

Cartier Tank Louis Review

The Cartier Tank is one of the most thoroughly and exhaustively discussed watches of all time. At one point or another, the Cartier Tank has been worn by JFK, Princess Diana, Ralph Lauren, Michelle Obama, Muhammad Ali, Andy Warhol… the list really goes on and on. The first Cartier Tank was a prototype worn by none other than U.S. General "Black Jack" Pershing, who was the commander of the Allied forces in World War I. And while the collection was formally debuted with the Tank Normale, it would be the Cartier Tank Louis that would go on to be synonymous with the iconic rectangular-cased watch. Of course, there is so much history and lore to get lost in with the Tank and our own resident expert, Mark Bernardo, did a complete job of it, which you can read here. The Cartier Tank Louis is an Art Deco classic that has inspired countless imitators but, as with all great things, there is the real thing and then there’s everything else.  Cartier Tank Louis Case  The contemporary Cartier Tank Louis comes in a few different sizes, starting with the mini quartz which is 16.5mm wide, 6.2mm thick, and 24mm tall; to the small mechanical, which is 22mm wide, 6.8mm thick, and 29.5mm tall; to the size I will be reviewing here, which is the large manual-winding model, which is 25.5mm wide, 6.6mm thick, and 33.7mm tall. There is also the automatic Tank Louis that was introduced at this year’s edition of Watches & Wonders, which is 27.7mm wide, 8.18mm thick, and 38.1mm tall. When mos...

Doxa Adds a Steel Bezel to the SUB 200 Diver Worn & Wound

Doxa Adds a Steel Bezel to the SUB 200 Diver

Doxa added a GMT to their collection for the first time in years to much fanfare recently (we covered it here). This watch got quite a bit of press and stirred considerable interest within the enthusiast community, but to my mind it was only the second best watch the brand showed us when we met with them in Geneva last month (that’s second out of two, just to be clear). I’m not sure what it is, exactly, but I’m a little over the whole “put a GMT on it” approach to product development that the industry has been stuck in for the last few years. Do we really need the ability to track two or more time zones on every watch? And should we really be doing it with movements that perform this function almost by accident and are nearly impossible to use correctly if you’re actually traveling? I’m trying not to be a hater, really I am, but every time I see a new GMT equipped watch that’s just a riff on an existing diver or chronograph, as if a GMT complication is just an extra side on a barbecue platter, I ask myself what it is that we’re doing here, really.  A new version of the Doxa SUB 200 was the other watch Doxa was showing in Geneva last month, although it was embargoed until last week, so I couldn’t come out of that meeting with the blistering hot take that it actually makes a lot more sense as a watch than the SUB 250T GMT, which to me feels like something ChatGPT might invent if you asked it to think of Doxa watches that don’t yet exist. This SUB 200 i...

Record Breaking Konstantin Chaykin ThinKing Debuts at Auction SJX Watches
Patek Philippe Calibre 89 ref 989J May 2, 2025

Record Breaking Konstantin Chaykin ThinKing Debuts at Auction

If you want to own the world’s thinnest mechanical watch, the Konstantin Chaykin ThinKing, you’ll have to fight for it at The Geneva Watch Auction: XXI, which will see the first production example go under the hammer. The 1.65 mm stature of the ThinKing is even more impressive coming from a small Russian independent watchmaker, considering previous records were set by big Swiss brands ranging from Piaget to Richard Mille. Notably, this is not the first time a landmark release has been trusted to an auction that isn’t linked to a charity. The most famous example of this was the Patek Philippe Calibre 89 (ref. 989J) back in 1989 at Antiquorum’s thematic sale. The ThinKing will be sold in the first session of the auction, which starts on May 10, 2025, at 2 pm. The ThinKing in profile. Image – Phillips Mr Chaykin achieved the record-setting height with clever construction, including a “double balance wheel” system that places an intermediate wheel between the balance and escapement, allowing both to sit on the same plane. Another notable technical feature is a barrel that is open on both sides, and no thicker than the mainspring itself. And unlike most serially-produced Konstantin Chaykin watches, each ThinKing is made, finished, and assembled by Mr Chaykin himself. Wearability is enhanced by the bolt-on protective shroud in titanium christened “PalanKing”. This increases the height to 5.4 mm, but adds key-less setting and winding, and automatic winding by a...

Studio Underd0g Introduces the Av0cado and Guacam0le Chronographs, a Clever Response to their Imitators

In our current age of disingenuous AI and copyright controversies, sometimes the best way to beat a design thief is to…imitate them right back? In perhaps the cheekiest move we’ve ever seen a watchmaker execute in response to an influx of copycat designs from no-name brands, Studio Underd0g has done just that. Instead of taking the legal route-an endeavour that is time-consuming, costly, and largely pointless in today’s world of mass-production and dropshipping-the British watchmaker has employed a tactful play of horological judo, and  produced two new models inspired wholeheartedly by the very designs stolen from them. Enter the Av0cado and Guacam0le, just as colorful, cheerful, and charismatic as the rest of their lineup, with an extra dollop of good humor on the side.  Take one look at the knockoffs from a myriad of random “brands” and you’ll see what Studio Underd0g is talking about. The color schemes, design cues, and even text details are shamelessly ripped straight from the authentic watchmaker’s catalog. This is, of course, the sharp side of the double-edged sword for a brand with a visual style as instantly recognizable as Studio Underd0g’s, even given their relative youth as a company; when you create a style that resonates with so many people, you’re bound to have imitators.  They haven’t cut any corners with the Av0cado and Guacam0le, though, despite the comedic backstory. Both are in direct response to a company called Proxima’s k...

Recently, Seiko released a pair of new models – SRPL07 and SRPL09 – […]

Omega Unveils Seamaster Planet Ocean Worldtimer SJX Watches
Omega Unveils Seamaster Planet Ocean Apr 6, 2025

Omega Unveils Seamaster Planet Ocean Worldtimer

Omega’s latest is an unusual combination of a 600 m-rated dive watch with a Cottier-style world time. The Seamaster Planet Ocean Worldtimer shares the oversized ceramic case of the Planet Ocean Deep Black, but is the first model in the collection to incorporate a world time complication. Initial thoughts While the Worldtimer makes a bold statement, a US$14,800 price tag and substantial case dimensions may limit its appeal – particularly for those with average-sized wrists. Still, it offers a somewhat paradoxical and oddly specific combination of features, so someone seeking a world time watch ready for saturation diving, there are few other options. Of the two available colourways, I would choose the low-key grey edition for its greater versatility compared to the turquoise version. Worldtimer Offered with either turquoise or grey accents, the new Planet Ocean is housed in a black ceramic case measuring 45.5 mm in diameter and 17.4 mm in thickness. Signature Seamaster case elements, including twisted lyre lugs, a helium escape valve, and “Broad Arrow” hands, complete the design. The standout feature the world time complication with a cities disc and 24-hour ring. At the centre is a titanium disc displaying a view of the Earth from the North Pole, with continents and colours rendered with varnish and laser engraving. A 24-hour ring in transparent hesalite is shaded in black and white to denote night and day. The chapter ring for the hours is embellished with a honey...

Hands On: Jaeger-LeCoultre Reverso Tribute Geographic SJX Watches
Jaeger-LeCoultre Reverso Tribute Geographic Apr 1, 2025

Hands On: Jaeger-LeCoultre Reverso Tribute Geographic

For the first time since 1998, and for only the second time in the nearly 100-year history of its most iconic model, Jaeger-LeCoultre has squeezed a world timer into the Reverso. The result is the Reverso Tribute Geographic, which features a demure primary dial with an outsize date on one side and an exquisite world time display on the other. The Geographic is available in a stainless steel case with a blue dial or as part of a 150-piece limited edition in 18k rose gold featuring a chocolate brown dial. Both models share the same dimensions, which are unfortunately a bit on the large side. Initial thoughts There’s a lot to like about the Reverso Geographic. Reversos like this that hide a complication on the second dial are deeply appealing to me, and carry with them the thrill of keeping a secret. It also gives the watch a split personality, enabling the wearer to choose the dial that matches their mood. While I immediately liked the concept of the Geographic, I was slightly disappointed to see the dimensions, which match those of the Reverso Tribute Chronograph launched in 2023. At 49.4 mm long by 29.9 mm wide, the Geographic is among the larger Reversos, meaning it loses some of the intended vintage charm. That said, the size is a consequence of its functionality – a smaller case size would make the world time display unreasonably small. One of the things I liked about the Tribute Chronograph that also applies to the Geographic is the fact that it’s very much a sle...
