Ulysse Nardin Introduces the Military-Inspired Diver OPS SJX Watches
Ulysse Nardin Introduces May 27, 2024

Ulysse Nardin Introduces the Military-Inspired Diver OPS

Ulysse Nardin just dropped the Diver Net OPS and Diver X Skeleton OPS, a pair of military-inspired sports watches made from sustainable materials. Dressed in olive drab and black, the two watches utilise recycled steel and carbon composites, and even nylon straps made from fishing nets. Though the emphasis on sustainability and styling are clearly modern, the basis of the watches is historical: the design is modelled on the shipborne marine chronometers Ulysse Nardin was once famous for. The Diver X Skeleton OPS with its open dial Initial Thoughts Ulysse Nardin opted for more restrained aesthetics for the new Diver Duo, instead of the brighter colours found on past models. The Diver Net OPS in particular has a low-key, functional look. Notably, the trademark “X” motif on its dial – which you either love or hate – is not particularly obvious. I find the “X” too bold on some other designs, but here it works better with the military-esque look of the dial. However, both the materials and movements found inside the two watches reflect the brand’s focus on advanced, industrial watchmaking. The Diver Net OPS, for example, is an entry-level model but still equipped with an in-house movement with a silicon hairspring and free-sprung balance, along with a diamond-coated escapement. The Diver Net OPS And the use of recycled materials is also interesting. The carbon composite parts of the case are offcuts from the aircraft manufacturing, which according to the brand red...

Hands-On With The Yema Navygraf Slim CMM.20 Limited Edition - Powered By An In-House Micro-Rotor Movement

It’s been a little over a year since Yema introduced the current version of the Navygraf. The brand’s Navygraf II from the late ’70s inspired the design of the watch. I had a chance to go hands-on with the Navygraf Marine Nationale GMT last year, and I liked it. The updated style and the great […] Visit Hands-On With The Yema Navygraf Slim CMM.20 Limited Edition - Powered By An In-House Micro-Rotor Movement to read the full article.

Hands On: Barbier-Mueller Mosaïque II SJX Watches
F.P. Journe Chronometre Souverain May 6, 2024

Hands On: Barbier-Mueller Mosaïque II

One of the most esoteric offerings in Only Watch 2024 is the Barbier-Mueller Mosaïque II. A follow-up to the first edition made in 2017, the Mosaïque II sticks to the same template that was originally inspired by a 19th century pocket watch with an inlaid case. It’s essentially an F.P. Journe Chronometre Souverain with a slightly larger case inlaid with semi-precious stones and a hinged hunter back. This also makes F.P. Journe the only brand with two watches – the other is the Chronomètre Furtif Bleu – in the upcoming charity auction that takes place on May 10, 2024. Initial thoughts I liked the original version because it was recognisable as an F.P. Journe watch, yet entirely different. The Mosaïque II holds the same appeal, albeit at a far higher price given the increased demand for F.P. Journe in the years since. While in 2017 one could reasonably hope to buy the first Mosaïque for a high five-figure price – in fact it sold for a trifling CHF90,000 – the Mosaïque II will almost certainly end up in the high six- or even seven figures. Affordability aside, the Mosaïque II is a little more interesting than its predecessor because of the floral motif as well as the materials; the bloodstone inlays are a particularly striking backdrop for the other stones. The inlays are also more complex, with both the dial and back inlaid with stones in a mix of shapes and sizes.

Explained: Bovet Solves Daylight Savings Time in the Wristwatch

The Bovet Récital 28 Prowess 1 is an ingenious solution to an age-old problem: accounting for daylight saving time (also known as summer time) in a multi-timezone wristwatch. Despite the seemingly simple nature of the problem, the solution is extraordinarily complicated, requiring two dozen rollers and many more gears and springs. With its roller-based world time mechanism, the Récital 28 can easily switch between showing summer or winter in both Europe and America, making the first-ever wristwatch able to do that. Initial thoughts Bovet’s complicated watches are usually enormous, intricately mechanical, and sometimes extravagantly decorated, sometimes sporting pearls, diamonds, and enamel work. The Récital 28 is less decorative but intensely mechanical. With clever engineering, the calibre inside addresses one of the longstanding challenges of a travel-time watch, accounting for daylight saving time (DST). The cleverness of the Récital 28 lies in its rollers, which each have four positions. This allows time zones to be easily backwards or forwards in accordance with DST. Even though the solution is straightforward in principle, executing it is immensely complex. In order to accommodate its many functions, the R28-70-00X movement incorporates multiple subassemblies that make it a unique proposition. As a result, the movement in the Récital 28 is unusually complicated, especially for what is essentially a world time watch. Its part-count of 744 puts it in grand comp...

Introducing - Grand Seiko Revisits its 1960 Icon with the SBGW314 Hoshizukiyo

In 1960, a team of Seiko engineers produced a watch that encapsulated precision, durability, refined execution and beauty. Launched in a 35mm yellow gold case with a slim, chronometer-rated movement, the specifications of the new watch were so well calibrated that it was christened the Grand Seiko. Celebrating Grand Seiko’s official independence from Seiko in […]

Watch Lume 101: The Complete History and Primer on Reading Time in the Teddy Baldassarre

Watch Lume 101: The Complete History and Primer on Reading Time in the

Luminous material on watch dials - referred to in shorthand as “lume” by both industry insiders and avid enthusiasts - is an element taken for granted nowadays. It can be said without hyperbole that a watch dial without lume is a stylistic outlier in this modern era, but this wasn’t always the case. Discerning the time in the dark presented a major problem for watchmakers in the early days before the widespread use of electricity in homes, and at first the only solution that could be offered was an audible rather than visual one: watches that chimed the time on demand, like minute repeaters and sonneries. Only a handful of wealthy individuals could afford these highly complicated timepieces, however, so a more widely accessible technology was needed as wristwatches spread to the general populace. Around the dawn of the 20th Century, watchmakers turned their attention to making watch dials that could be read in the dark, paving the way for the luminous materials that are still used commonly today. The road to perfecting the technology, however, would not be easy, and at times would even be dangerous. Radium The first material applied to watch dials for nighttime luminescence was a paint made from radium with zinc sulfide, which, thanks to radium’s half-life of 1,600 years, offered a long-lasting glow during that period before dimming - the catch being that radium, as its name implies, is radioactive. One of its earliest uses can be traced to a pioneer of devel...

Zenith Introduces the Chronomaster Sport Titanium SJX Watches
Zenith Introduces Feb 12, 2024

Zenith Introduces the Chronomaster Sport Titanium

Zenith has just taken the covers off the Chronomaster Sport Titanium, essentially a lightweight variant of the bestselling sports chronograph. Entirely in brushed and polished titanium, the new Chronometer is powered by the El Primero 3600 and like most sports chronographs today, available with either a matching titanium bracelet or an integrated rubber strap. Initial thoughts The Chronomaster Sport Titanium doesn’t do anything new in terms of styling – the design still remains derivative of the Rolex Daytona – but it feels good in the lightweight alloy. The watch has the large size required of a sport chronograph, but is easily wearable thanks to the lightness. As an accessible alternative to the Daytona, the Chronomaster Sport is not particularly interesting in steel, but more appealing in titanium. Granted, it retains the same design, but the titanium case and bracelet give it a tangibly different feel. Of all the Chronomaster Sport iterations, this is the most appealing, particularly since it’s the only variant dressed in low-key, monochromatic colours. The grey hue of titanium complements the palette, with the tri-colour sub-dials in shades of grey being a clever touch. The Chronomaster Sport Titanium is priced at US$11,800 on a bracelet and a bit less on a strap. It’s priced comparable to other Zenith models with the same movement, and broadly speaking a good value proposition as far as sports chronographs go, with the Daytona being about 40% more expensive...

Why I Bought It: The Zenith Chronomaster Tribute to Charles Vermot - Reprise

Quentin R. Bufogle could go on and on about the Zenith Chronomaster Tribute to Charles Vermot’s stunningly beautiful, metallic blue dial, silicon escapement (visible via the open heart feature), COSC chronometer certification and that it’s one of the last truly great Chronomasters, but that would be missing the point, i.e. how Charles Vermot saved Zenith.

Blancpain & Swatch Introduce the Bioceramic Scuba Fifty Fathoms “Ocean of Storms” SJX Watches
Blancpain & Swatch Introduce Jan 10, 2024

Blancpain & Swatch Introduce the Bioceramic Scuba Fifty Fathoms “Ocean of Storms”

Just days a week into the new year, Blancpain and Swatch announce an all-black variation of the Scuba Fifty Fathoms, their affordable collaboration introduced last year. The Ocean of Storms retains all the distinctive features of the model, namely a 42.3 mm Bioceramic case containing the Sistem51 automatic movement fitted with a rotor bearing a nudibranch (a shell-less mollusc for those unfamiliar with esoteric marine creatures). Priced at US$400 as before, it will be available at select Swatch boutiques starting January 11, 2024. Initial thoughts When Swatch started teasing this new variant on social media, it seemed to be yet another one-off limited edition available for one day, like the MoonSwatch “Mission to Moonshine Gold” releases last year. However, as more details emerged, it became apparent that this was not the case as this will be part of the permanent collection, bringing the number of Scuba Fifty Fathoms models to an even six. At first glance, the Ocean of Storms bears a striking resemblance to last year’s Fifty Fathoms 70th Anniversary “Act 1”, a high-end watch that is an actual Blancpain, particularly with the date window and notched bezel. Nevertheless, adjustments to the design set it apart from its pricier cousins as well as its siblings in the Scuba line. It is clearly the most monochromatic and low-key of the range. Priced at US$400, the Ocean of Storms is priced the same as the other variants, retaining its fun and affordable appeal. However...
