COSC Upgrades Standards to Certify More Than Timekeeping SJX Watches

COSC Upgrades Standards to Certify More Than Timekeeping

Interesting news just out of Contrôle Officiel Suisse des Chronomètres (COSC), the venerable Swiss chronometer testing body, which has just announced a major revamp to its testing to honour the COSC’s standard’s 50th anniversary. Excellence Chronometer, COSC’s new and improved certification program, goes beyond the ISO 3159 norm that has defined its tests for decades. Instead of just testing movements, Excellence Chronometer will require completed, cased watches to run within -2/+4 seconds a day, as well as pass wear simulation and magnetism tests. Initial thoughts While COSC remains the primary chronometer testing body in Switzerland, thanks largely to Rolex, its protocols have been due for an update for some time now. With the rise of alternative and in-house precision testing programs, the standard chronometer certification can sometimes feel left behind. Rolex’s own Superlative Chronometer certification first requires a COSC certificate, but then makes sure the watches run at -2/+2 seconds per day after further in-house testing. The METAS Chronometer program also requires the standard COSC certificate, but guarantees a regulation of 0/+5 seconds per day and a great resistance to magnetic fields. Seeing that COSC slowly updates and imposes more stringent criteria is a good sign, but it may still not be good enough. With the rise of advanced internal certification programs, it looks like some brands submit their models to COSC testing just to make sure they can...

Biver Reveals Unique Automatique for Charity SJX Watches

Biver Reveals Unique Automatique for Charity

Although it’s been less than two years since its founding, Biver has already launched its second model, the Automatique. Using that as the base, the brand created the Automatique “Echoes of this Moment”, a unique piece crafted in collaboration with a Swiss artist for TimeForArt, a charity auction taking place in November to benefit the Swiss Institute, a nonprofit focused on contemporary art education. Initial thoughts The standard Automatique is undeniably a finely executed watch, especially the micro-rotor automatic calibre within. Although the aesthetics of the regular-production model aren’t perfectly cohesive, the exquisite quality of the movement and attention to detail make it one of the most interesting new time-only creations from an independent. This unique piece improves the aesthetics of the Automatique because it simplifies the design. The standard version has an elaborately finished dial that combines too many elements – faceted indices, brushed sectors, an engraved seconds track, and sharp polished hands. In contrast, the unique Automatique keeps the look simple, while still having a complex, artisanal dial decoration. Here the handmade dial – that’s both engraved and enamelled – can be admired for what it is, with no distractions. An artful dial The New York-based Swiss Institute was set up to promote contemporary art through events and exhibitions. Now in its second edition, TimeForArt was conceived to benefit the non-profit. Biver is one o...

In-Depth: A Dive Into the Oyster Perpetual Rolex Deepsea SJX Watches

In-Depth: A Dive Into the Oyster Perpetual Rolex Deepsea

While the history of the Rolex diver’s watch begins with the Oyster Perpetual Submariner of 1953, one of the brand’s landmark achievement in water-resistant cases is more recent: the Oyster Perpetual Rolex Deepsea launched in 2008 that incorporates the Ringlock system. With the innovative Ringlock system, Rolex surmounted an enduring obstacle in building a deeper-diving watch – a case that grew in proportion to the depth rating. The Ringlock system is a patented case architecture that fundamentally rethought the traditional approach to a diver’s watch, which allowed the Rolex Deepsea to achieve a water-resistance rating of 3,900 m with a 44 mm case. The utility of the Ringlock was proven in 2022 with the Oyster Perpetual Deepsea Challenge that took the Oyster case to the limits of horological engineering. Featuring a 50 mm case in RLX titanium, the Deepsea Challenge is water resistant to 11,000 m – the all-time water-resistance record for a mechanical wristwatch. The latest addition to the deep-diving collection, the Oyster Perpetual Rolex Deepsea in 18k yellow gold. Image – Rolex A deep history The history of Rolex is inextricably intertwined with the water-resistant wristwatch. Six years after establishing the brand in 1908, Rolex founder Hans Wilsdorf wrote to Bienne-based movement maker Aegler, “We must find a way to create a waterproof wristwatch”.  By 1926, Wilsdorf had achieved his goal with the launch of the Oyster, a waterproof wristwatch which ha...

Just In Time For Summer: Five Divers Under $1,000

Few kinds of watches are as universally beloved as the dive watch. For myriad reasons – durability, legibility, history, and more – the classic dive watch, for essentially its entire history, has been a smashing success. We think it’s easy to see why: diver’s watches capture a sense of adventure and (mostly) anachronistic utility that still feels cool today. Their aesthetic has never really gone out of style, and there is no arguing that a solid dive watch is exactly what a lot of enthusiasts think of when they imagine what a “nice watch” is. Like with EDC gear or sports cars, there’s a sense of enjoyment of knowing that our tools are more than up to the task. Thankfully, an entry into the dive watch game doesn’t cost an arm and a leg; in fact, here are five dive watches under $1,000 that we would strap on any day for life’s adventures. Without further ado, let’s, um, dive in. Few kinds of watches are as universally beloved as the dive watch.

Nubeo Introduces a Collection of Fun, Colorful Divers with Impressive Specs

Nubeo is a brand that takes its inspiration from both sea and space in tribute, in function and in design. Their latest dive watch is named after the Ventana remotely operated vehicle. This scientific submersible is rated to a depth of over 1700 meters, and for 30 years and somewhere north of 4,100 dives it is the most experienced and enduring ROV in the world. This diver sure looks the part and with 1000m of water-resistance, it can also do the part. The perfectly round stainless steel case is a whopping 50mm in diameter, but similar to everyone’s favorite Japanese dive watch nicknamed after a delicious sandwich fish, there are no lugs. The strap directly attaches to the watch underneath each side, in a hooded fashion. Therefore, despite its girth, just about anyone should be able to wear it. All of the Ventana variants feature a deep wave patterned dial, with a flush helium escape valve at 9 o’clock and, believe it or not, a captive bezel held in place by large screws. The extra-large hands and indices, along with the oversize bezel pip are filled with a copious amount of lume. Powering the Ventana is the automatic, Seiko built, NH35 movement, and all come on a specialized, thick silicon strap, ready for action. Finishing the year with a bang, Nubeo has introduced 4 new colorways, each limited to 400 pieces. First there is the Basalt Grey, for those that prefer a more conservative look. Its bezel insert is a half-half split of black on top and, as the name implies, g...

Oris Divers Sixty-Five Review Teddy Baldassarre

Oris Divers Sixty-Five Review

The Oris Divers Sixty-Five collection has found a receptive and substantial audience since its introduction in 2015, firmly establishing itself as one the Swiss brand's most versatile and creatively innovative product families. Whether it's the retro appeal of its original 1960s design, the exclusivity of the Carl Brashear editions, or the playful pastels of the Cotton Candy models, the Oris Diver Sixty-Five has something for just about any type of watch enthusiast. Here is a comprehensive rundown of the line, from its mid-sixties inspiration to today.  1965: The Original Waterpoof Oris started making watches in 1904 in the Swiss town of Hölstein, where it is still based today. The brand made its first purpose-built dive watch in 1965, naming it the Oris Waterproof and targeting the era’s growing masses of recreational diving enthusiasts - many of whom were likely seeking a more affordable alternative to prohibitively priced genre pioneers like the Rolex Submariner and Blancpain Fifty Fathoms. The Waterproof was a product of its time, with a case made of chromium-plated brass, a crystal made of Plexiglas, and a strap made of sturdy but decidedly non-luxurious black rubber. The case, with a dive-scale bezel that rotated in both directions, measured a rather modest 36mm and housed a manually wound mechanical movement, the 17-jewel Oris Caliber 654; at the time, Oris made most of its own movements in-house. This historical divers’ model (above, right), while never a...

Daniel Roth’s Latest is Extra Plat-inum SJX Watches
Louis Vuitton s La Fabrique du May 7, 2026

Daniel Roth’s Latest is Extra Plat-inum

Daniel Roth’s latest addition to its time-only portfolio is the Extra Plat Platinum. A familiar face in a new colourway, the Extra Plat offers the Tourbillon Platinum‘s stealthy look in a more accessible two-hand format. Powered by the DR002 in-house calibre developed by Louis Vuitton’s La Fabrique du Temps (LFT), this regular production model brings a decidedly subtle look to the brand’s simple dress watch. Initial thoughts It’s been interesting to observe Louis Vuitton’s confident foray into haute horlogerie through the revival of Daniel Roth. Despite the corporate structure, astute collectors continue to speak of Daniel Roth in the same breath as other leading independent watchmakers. To the independent-collecting cognoscenti, the platinum Extra Plat should prove a compelling option – rooted in the early history of the independent watchmaking movement but built to meet contemporary expectations. Following Daniel Roth’s launch of the Tourbillon Souscription, the time-only, manually wound Extra Plat — “extra flat” for non-French speakers — debuted in an 18k yellow gold souscription edition followed closely by regular production models in rose gold, with and without skeletonisation. The new platinum Extra Plat rounds out the set. Combined with the matching dial with contrasting finishes, it creates a rather stealthy profile for this otherwise opulently finished dress watch. Extra Plat-inum The platinum double-ellipse case shares the wrist-friendly d...

Announcements: Hodinkee Australia And New Zealand Is Live

At Hodinkee, we have always believed that watch collecting is a global language, but one that is spoken with many different local accents. From the paved paths of Geneva to the neon-lit boutiques of Ginza and the steamy streets of New York City, the love for a mechanical heartbeat remains the same, yet the way we live with our watches is shaped entirely by the world around us. Today, we are thrilled to announce the next chapter in our journey: the official launch of Hodinkee Australia & New Zealand. The ANZ watch community has long been one of the most sophisticated and passionate in the world. For years, we've watched from New York as the Aussies and Kiwis became some of our communities' most ardent enthusiasts, known for a taste profile that is as rugged as it is refined. To bring Hodinkee to the region, we have partnered with Switzer Media + Publishing. With over 30 years of history, Switzer is one of Australia's most trusted names in media, already stewarding iconic titles like Harper's BAZAAR, Esquire, and Men's Health. This partnership functions as a local element from day one.  Speaking from my own perspective, with the continued success of Hodinkee Japan, I'm thrilled to be working with Jamie and the team at Switzer Media to offer a more locally relevant and engaging edition of Hodinkee for watch enthusiasts across Australia and New Zealand. The watch community in Australia and New Zealand is engaged, highly knowledgeable, and always an active part of the global c...

Singer’s DualTrack is its First Twin Time Zone GMT SJX Watches
Rolex GMT-Master II Apr 12, 2026

Singer’s DualTrack is its First Twin Time Zone GMT

Having debuted its first proprietary movement inside the Caballero last year, Singer Reimagined is building on the calibre by adding a second time zone. The DualTrack is powered by the same cleverly constructed movement, a manual wind with an impressive six day power reserve, but gains a 24-hour ring for a GMT function. The watch adopts the cushion-shaped case that’s the brand signature, while the dial similarly preserve the aesthetic found on the brand’s trademark central chronographs, but with a 24-hour ring around the dial. Because the second time zone is an add-on over the calibre, the 24-scale ring is independently adjustable, rather than the local hour hand, making this “caller” GMT rather than a true “traveller” GMT. Initial thoughts I like the Singer aesthetic so this design is appealing, and it implements the dual time zone function logically and legibly. The in-house movement with a long power reserve is also a plus, especially since it has a novel four-barrel construction. The only downside here is the “caller” type second time zone function. A “true” GMT with an independent local hour hand, as found on the Rolex GMT-Master II, is the most convenient format, since it requires fewest steps when setting the time while travelling, but this requires a built-from-the-ground-up calibre. All things considered, that can be forgiven since the DualTrack is an attractive proposition overall. Like last year’s Caballero, the DualTrack is a useful watch ...

Franc Vila’s FVF2 Time & Day is Quirky Haute Horlogerie

FVF Genève’s second model after the FVF1 skeleton tourbillon, the FVF2 Intrepido Time & Day is a more concise and accessible watch. It’s essentially a familiar formula – time (plus day) and a hand-finished manual wind movement – the FVF2 nonetheless manages to stand out thanks to brand founder Franc Vila’s eye for design. Pictured here with a black mother of pearl dial, part of a five-piece edition, the FVF2 has a pleasing asymmetry. The movement is composed of intriguing geometric forms and quirky details like the square winding click, while also being traditionally decorated with generous bevelling and black polishing. The case is an unusual “unibody” construction where the base plate and case middle are one and the same Initial thoughts The FVF2 might seem like yet another time-only watch with a fancily decorated movement, and it is just that, but not quite. Its creator, Franc Vila, is an industry veteran rather than a newcomer, and is now making a comeback after rising and falling with his original brand some two decades ago. Unlike many recent calibres that try to do more with more, the FVF2 movement is more minimalist but has a recognisable style and artful details. The calibre is characterised by geometric forms that encompass finer elements like the winding click, while also retaining a clear classical bent with the prominent going train and finishing. The treatment for the titanium base plate requires superheated gases to create an oxide layer on t...

Universal Geneve is Back – Here’s the New Polerouter

While the watch industry braces for Watches & Wonders next week and anticipates a flurry of new releases to discuss that will take us through the next several months of watch discourse, today is actually the day that many collectors and enthusiasts have been waiting for for years: the debut of new watches from Universal Geneve. When it was announced that the brand would be formally relaunched by Georges Kern back in December of 2023, speculation began immediately as to what we would eventually see. Little tidbits have come out in dribs and drabs over the last two years, but today the watch community finally gets a look at what Universal Geneve will be in the modern era, at least to start.  A few things are very apparent from the outset. This is a big swing on the part of Kern and others steering the ship at Universal. They could have gone small, and introduced a one or two references to reintroduce the brand to the community slowly, but instead they’ve come out o the gate with nearly 40 SKUs, with prices ranging from a relatively modest $14,000 all the way up to $320,000 for an elaborate jewelry focused Cabriolet (and that’s the only elaborate, jewelry focused piece). The other thing that’s clear is that the launch feels focused on the Polerouter, a Gerald Genta design that is likely the most well known watch under the broader Universal Geneve banner. It got the reference book treatment a few years back, and, once upon a time, was one of the most frequently recommen...

Stéphane Pierre’s Inaugural L’Impétrant is Bi-Retrograde SJX Watches
Apr 2, 2026

Stéphane Pierre’s Inaugural L’Impétrant is Bi-Retrograde

A new independent voice emerges with the L’Impétrant, the debut watch from Stéphane Pierre, combining a bi-retrograde time display with an architecturally distinctive movement. Put together by an all-star roster of specialists, the L’Impétrant is a fresh take on a familiar format. Initial thoughts The central question with any debuting independent is whether ambition matches execution. Stéphane Pierre’s L’Impétrant is quirky and eccentric - and just as importantly seems well made thanks to the efforts of some 20 contributing specialists across fields such as movement construction, machining, electroplating, stamping and finishing. Given the evergreen popularity of the high-end, time-only format, it may well find its audience. The L’Impétrant’s visual staple is a set of enormous 19 mm retrograde hands - one for the minutes and the other for the hours. The bi-retrograde complication is no longer uncommon, but The L’Impétrant’s overlapping arrangement of the hands, and the luxurious construction of the mechanism, is unusual, helping it stand out within this niche. The mastermind behind the L’Impétrant has had an unusual career. Stéphane Pierre originally trained as a mechanical engineer and, intriguingly, has spent time working for both the Swatch Group and in the military sector. The L’Impétrant is essentially a very high-end time-only watch, and as such it enters a crowded market. However, rather than just developing a basic time-only watch...
