The Yema Navygraf is the Latest Diver to get the Mother of Pearl Treatment Worn & Wound

The Yema Navygraf is the Latest Diver to get the Mother of Pearl Treatment

There is something about mother-of-pearl that seems to be catching watchmakers’ eyes lately. While I highly doubt it has to do with the fact that “Mother of Pearl” is a phenomenal drag name, I can’t totally rule that out as a possibility. Instead, more likely, it has to do with the ease in which adding the iridescent substance onto an existing design gives it new personality without really reinventing the wheel. Case in point: Yema’s Navygraf Pearl. Undoubtedly, the Navygraf is a handsome watch. But, like a drag queen, sometimes it’s hard to describe something as both “handsome” and “pretty” simultaneously. At least, that was my first impression of this French-made watch. Using the classic dive watch model, like the Navygraf, and inlaying mother-of-pearl seemed, in a way, incongruous to the steely, masculine athleticism of the silhouette. But, upon examining the bezel and dial a little more closely, I’m more inclined to think this is less of a gimmick and more of a thematic appreciation for the beauty and sport that the ocean provides (unfortunately, I’m only speculating – the press release was more focused on the technical specs of this Navygraf). So, what are the specs? This is a thinner Navygraf variant, equipped with a micro-rotor caliber CMM.2, meaning that the 316L stainless steel case measuring 39mm, only clocks in at 9.75mm thickness. The CMM.2 caliber also promises around 70 hours of power reserve, making it suitable for any diving trips ...

Introducing – The Airain Type 20 “70 Ans”, a Horizon-Blue Tribute to the French Flyback Chronograph Monochrome
Breguet Mathey-Tissot Oct 24, 2025

Introducing – The Airain Type 20 “70 Ans”, a Horizon-Blue Tribute to the French Flyback Chronograph

Born from the French Ministry of Defence’s Type 20 brief in the mid-1950s, the Type 20 Chronograph watches featured a black dial, a flyback (retour en vol) function, a rotating bezel, and pilot-proof robustness. Alongside fellow suppliers like Breguet, Mathey-Tissot, and Auricoste, Airain’s Type 20 quickly became one of the most recognisable field chronographs. A […]

A Twist on Travel Time with the Richard Mille RM 63-02 Worldtimer SJX Watches
Richard Mille RM 63-02 Worldtimer World Oct 24, 2025

A Twist on Travel Time with the Richard Mille RM 63-02 Worldtimer

World time watches are notoriously imperfect, often out of sync with the realities of daylight savings and partial-hour time zone offsets. Yet their appeal endures thanks to their mechanical ingenuity and jet-set romance. The Richard Mille RM 63-02 Worldtimer stands out in both respects, with a planetary differential that enables the wearer adjust time zones with a simple twist of the bezel. Limited to just 100 pieces, the RM 63-02 offers commanding presence thanks to its 47 mm case in 18k rose gold and titanium, and its bold pink and burgundy colourway. While not a fit for every wrist or every budget, it’s nonetheless more wearable and accessible than expected. Initial thoughts From a strictly practical standpoint, the standard format for world time watches is inherently flawed, as about half the world observes daylight savings time for about half the year, and a fifth of the world’s population lives in time zones with partial-hour offsets. Flaws aside, they capture a certain jet set romance, and are frequently beautiful or clever. Richard Mille’s world timers are the latter, and maybe even the former too, depending on your disposition. The RM 63-02 is clever in its operational and conceptual simplicity, though the actual implementation is quite sophisticated, enabling the user to adjust to local time with a simple turn of the bezel. This functionality is reminiscent of the IWC Timezoner, which was itself based on a patent acquired from Vogard. Richard Mille’s app...

Patek Philippe’s Gondolo Serata Zebra Debuts New Dial Technique SJX Watches

Patek Philippe’s Gondolo Serata Zebra Debuts New Dial Technique

Patek Philippe surprises with an off-season launch, the Gondolo Serata Zebra Ref. 4962/200R-010. Based on the curvaceous model launched in 2006, the Zebra features a sapphire crystal dial framed by garnets on the bezel and lugs. The dial motif replicates the cloisonné enamel dial of the Golden Ellipse ref. 5738/50G-023 from the Rare Handcrafts collection of 2022, but here the technique and material are decidedly modern. Despite the radically different look, this is an evolution of the Retrograde Perpetual Calendar ref. 6159G that has a smoked sapphire dial. Here the dial is also clear sapphire, but engraved, varnished, and then metallised to create the striking zebra motif. Initial thoughts The Gondolo Serata has been in Patek Philippe’s catalogue for almost 20 years but it never really gained prominence. Though the case shape is elegant, the dials on the earlier versions were quite plain. The Zebra is the opposite – vivid and striking – and it instantly stands out amongst Patek Philippe’s ladies offerings. The fact that the dial motif is based on the Rare Handcrafts Ellipse is a nice touch, though watch enthusiasts may be disappointed the movement is quartz. Patek Philippe presumably understands its clients and those clients probably want the convenience of a quartz movement. The sapphire dial technique, however, is interesting enough that it is likely to make its way into other models, which will be a good thing. Savannah sapphire The Gondolo Serata is a longsta...

Seiko Revives Retro Rotocall from Eighties Space Shuttle Era SJX Watches

Seiko Revives Retro Rotocall from Eighties Space Shuttle Era

More Seiko watches have gone to space than any other brand, save for Omega and Casio, and Seiko brings back the most prolific of them all, the multi-function Rotocall. For the 2025 reissue, the brand has gone for authenticity over reinvention, retaining the original 37 mm case size and bezel-operated function selector, while making a concession for a more practical sapphire crystal. Named for its nifty rotating bezel, the vintage Rotocall was most frequently worn on NASA Space Shuttle missions. The remake is available in three colourways, plus two limited editions for the Japanese market, the reissue of this 1980s favourite delivers a heavy dose of nostalgia. Initial thoughts If the Speedmaster Professional is the “Moon Watch”, the Rotocall may as well be called the “Shuttle Watch”. NASA purportedly flight qualified the Rotocall around 1983 and, according to Robert Jackson, who maintains a database of watches used in space, Rotocalls crossed the Karman line nearly 200 times during the Space Shuttle program, which lasted until 2011. Today, vintage Rotocalls are quite desirable, and unlike NASA-issued Speedmasters, which were government property, astronauts paid for and were allowed to keep their Rotocalls. Sotheby’s sold Kathy Sullivan’s watch, which she took to space twice – and once to the seafloor in the Challenger Deep – for over US$20,000 a few years ago. The Rotocall may be the most faithful of Seiko’s recent reissues; it’s the same diameter – 37...

Zenith Chronomaster Sport Review: The Modern El Primero Teddy Baldassarre
Zenith Oct 15, 2025

Zenith Chronomaster Sport Review: The Modern El Primero

The Zenith Chronomaster Sport debuted back in 2021 and has evolved into one of the brand’s most compelling contemporary chronographs (and that’s saying a lot for Zenith). There was a lot of initial chatter about some similarities to the Rolex Daytona because the collection debuted with a panda and reverse panda dial model with ceramic bezel and, while the comparisons are certainly valid, it does warrant a reminder that the Daytona indeed used to be El Primero-powered. Earlier in 2025, Zenith went all out on the blue theme at this year’s Watches & Wonders in celebration of its 160th anniversary. The star of the show may have been the return of the Caliber 135 in the G.F.J. (see more on that one right here), but the supporting releases didn’t hold back either, boasting bright blue ceramic cases and bracelets. Together, this trio of watches comprise the Zenith 160th anniversary collection, touching on each of the cornerstones of the brand’s modern architecture. The watch I am going to focus on here is the Zenith Chronomaster Sport rendered nearly in its entirety in blue ceramic, showcasing a very different side of the brand’s most popular modern chronograph. Zenith Chronomaster Sport Context The Chronomaster collection has been around since 1994, building on the rather illustrious history of precision timing (outlined in more detail right here) that Zenith is known for. In 2021, Zenith found its modern stride with the release of the Chronomaster Sport with a blac...

First Look – Blancpain Updates its Villeret Collection with the 2025 Golden Hour Series

The latest Blancpain releases are classical watchmaking refined with a purpose. Long before the Villeret collection officially gained its name in 2003, Blancpain had already set the template in the early 1980s with a small, classically framed complete calendar moonphase (Cal. 6395). The look with the double-stepped bezel, Roman numerals, and slim cases became the […]

Daniel Arsham’s Hublot Meca-10 is Fluid, Frosted Sapphire SJX Watches
Hublot Meca-10 Oct 9, 2025

Daniel Arsham’s Hublot Meca-10 is Fluid, Frosted Sapphire

Following last year’s Arsham Droplet pocket watch, Daniel Arsham has just unveiled his second collaboration with Hublot, the MP-17 MECA-10 Arsham Splash Titanium Sapphire. One of the leading artists in pop culture, Daniel Arsham was inspired by the fluidity of a water droplet, explaining the streamlined, pebble-like wristwatch with an intriguing asymmetrical dial framed by a frosted sapphire crystal bezel. Mr Arsham has collaborated with brands as diverse as Porsche and Pokemon, and here he applies his aesthetic to Hublot’s Big Bang Meca-10. While the aesthetic is unlike any other Hublot, the movement inside is familiar: one of Hublot’s most interesting movements, the Meca-10 calibre with a 10-day power reserve, which was just facelifted this year to fit smaller format cases. Initial thoughts The Arsham Splash starts with a good base: the cal. 1205 Meca-10 movement is appealing both in terms of aesthetics and function. The geometric styling of the skeletonised construction is inspired by Meccano, the children’s construction toy, while the power reserve is an impressive 240 hours. I like much of the movement, except for the Etachron regulator that  I would have hoped Hublot would have replaced in this second-generation Meca-10 movement but it’s still there. Still, the Meca-10 is a logical fit for the Arsham Splash both in terms of form and function. The form of the Arsham Splash is unorthodox. Though the case has some familiar Hublot elements like the flared fl...

Rolex Daytona Rainbow: When An Icon Goes Colorfully Gem-Set

Aside from the watch that was made legendary by Paul Newman - and which would forever, unofficially, carry the famous actor’s name - there is probably no version of the Rolex Daytona that is more coveted than the “Rainbow” models that bring a meticulously designed and eye-catchingly beautiful assortment of colorful precious stones to the bezel, case, and dial of the motorsport-inspired luxury chronograph. Here is the story behind the Rolex Daytona “Rainbow” and why it has become yet another smash hit for the Crown in the 21st Century.  To start off, it’s worth answering the question, “Why is the Rolex Daytona so famous in the first place?” The model’s success story begins in 1962, when Rolex, hot on the heels of other genre-defining watch releases like the Explorer, GMT-Master, and Submariner several years earlier, became the official timekeeper of the “Great American Race,” the Daytona 500. In celebration of the partnership, the Swiss brand introduced its original “Cosmograph” racing-inspired chronograph watch the following year. The watch, notable for its tachymeter bezel and three-register dial design, adopted the name “Daytona” shortly thereafter and really took the enthusiast community by storm when actor, director, and part-time racecar driver Paul Newman began wearing one regularly. Newman became a big-screen icon in the 1970s, around the same time that auto racing took off in popularity as a spectator sport, and this confluence of...

Elegant Watches Are On The Rise, And It’s About Time

Let me make one thing clear: when I say that elegant watches are on the rise, I’m not referring to timepieces designed under the rule of restrained minimalism. Elegance doesn’t have to be quiet and introverted. Au contraire, swooping shapes, curvy lines, and delicate patterns are often outspoken, but the tone of voice prevents them […] Visit Elegant Watches Are On The Rise, And It’s About Time to read the full article.

Bulgari’s Aluminium collection erupted on the scene in 1998. Fusing design elements from earlier models like the 1975 Bvlgari Bvlgari with the twice-emblazoned brand name on the gold bezel, the slick Aluminium with its bold mix of lightweight aluminium and rubber accents was a runaway success.

Orient Gilds the Retro World Map SJX Watches
Vacheron Constantin Breguet Sep 2, 2025

Orient Gilds the Retro World Map

Orient celebrates its 75th anniversary with a limited edition World Map, inspired by a 1969 fan favourite and priced under US$400. Distinctly retro in style, the World Map features an unusual world time arrangement using a striking map and rotating bezel for global time zones. It’s well priced and well made, and a break from the brand’s usual staples, which tend to be affordable but plain. Initial Thoughts It seems 2025 is a year of many anniversaries: Audemars Piguet, Vacheron Constantin, Breguet, and of course, Orient. While never the most prominent Japanese watch manufacturer, Orient has built up a strong back catalog over 75 years, which includes the World Map. That said, I’d have preferred a reissue of the more formal looking World Trip, though I imagine the brand is saving that for the up-market Orient Star line. Beyond the watch, it’s important to remember that while Orient is a relatively small brand, it’s part of Seiko Epson, the company behind the Spring Drive UFA that made headlines this year (though a distinct entity from Seiko Watch Corporation that markets and sells Seiko and Grand Seiko watches). For the brand’s 60th anniversary, Orient equipped the Orient Star Skeleton with Japan’s first (and only) silicon escapement. With that in mind, it’s worth keeping an eye on Orient this year, as the brand has more to offer than just a pretty face. Post War Travel Ban and Boom In the aftermath of the Second World War Japan was devastated and isolated. ...

Albishorn Counts Down to First Anniversary with Marinagraph SJX Watches
Aug 27, 2025

Albishorn Counts Down to First Anniversary with Marinagraph

We’ve been following Albishorn since the brand launched just shy of a year ago, and have enjoyed the themes the brand has chosen to explore with its ‘imaginary vintage’ concept. After applying this formula to aviation and mountaineering, the Marinagraph returns to the brand’s patented regatta countdown function for another take on the yachting chronograph. Available in classic black or sunray brushed teal dial finishes, the Marinagraph adds an aluminium bezel insert to provide at-a-glance reading of the current state of the local tides. Each version is limited to 99 pieces, which will be produced in small batches over the next three years. Initial thoughts Albishorn made its debut with a regatta timer, and it’s nice to see another foray into this genre to mark the brand’s first anniversary. Though regatta timers are surely among the least useful complications, the Marinagraph adds a tide bezel that adds a simple way for coastal buyers to monitor their local tides. As a seaside resident myself, I find this feature quite charming and it seems on-brand for Albishorn. Two dial colours are on offer, each limited to 99 (non-numbered) pieces. I prefer the classic black dial, which feels more in line with the imaginary vintage theme, but the sunburst teal dial, dubbed Paraíba Racing, is arguably more on trend with the prevailing tastes of the moment. The Marinagraph retains the best elements of Albishorn’s previous chronographs, namely its distinctive bowl-shaped be...

Louis Erard Makes Hand Engraving Affordable SJX Watches
Louis Erard Makes Hand Engraving Affordable Aug 19, 2025

Louis Erard Makes Hand Engraving Affordable

Louis Erard’s niche is making either watchmakers or techniques affordable – the Gravée Main is hand engraving priced accessibly. The watch is entirely engraved by hand, across the bezel, case, crown, and buckle, with a classical leaf motif by Maksym Shavlak, a watchmaker and engraver from Ukraine. The resulting look is a blend of Gothic and Baroque, but the underlying watch retains the usual dimensions and movement of Louis Erard, while the dial is glossy black lacquer that evokes fired enamel. Initial thoughts I appreciate Louis Erard’s consistent focus on making interesting names or techniques affordable; its recent Damascus steel regulator being an example. Some micro-brands or one-man shops do the same for slightly less, particularly for certain decorative techniques, but without the finesse of Louis Erard. A good deal of credit for this goes to Manuel Emch, who oversees Louis Erard and lends his eye to the brand’s creations. The Gravée Main sits squarely in the sweet spot where Louis Erard excels. Admittedly, the ornate look is not for everyone, some might even find it tacky. But I like it; the look is appealing and the execution shows attention to detail. The tone-on-tone lacquered dial is a smart complement to the elaborate case. And that attention to detail is also evident in the engraving, which continues onto both the crown and buckle, which are sometimes overlooked. Price-wise the Gravée Main is pricier than the typical Louis Erard limited edition, bu...

Hands-on – Some Thoughts about the Rolex Daytona “Alcaraz” 126518LN with Turquoise Lacquer Dial

In recent years, basically since the introduction of the ceramic bezel on the steel edition (the 116500LN), the Daytona has become the hottest watch in Rolex’s portfolio, but also remained a fairly conservative model, with a rather parsimonious use of colours. This hasn’t always been the case, though, and in the past, we’ve seen wild […]
