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

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...

The 300m depth rating is for many people a marker of what a proper diver’s watch should be, and there are some obvious contenders out there.

Inside The Manufacture: Why Fam al Hut Is Pursuing Manufacture Status

This story is a special presentation from Hodinkee Japan, written and illustrated by Masaharu Wada, the Deputy Editor-in-Chief for Hodinkee Japan.  For a young brand to revisit roughly 98 percent of the movement components in a GPHG-winning watch after receiving the award might ordinarily sound like cause for concern. But when I visited Fam al Hut's workshop in Taicang, Jiangsu Province, China, I came away feeling almost the opposite. More than anything else, that fact seemed to capture exactly where the brand stands today. A large industrial elevator takes you to the second floor, where the doors open onto a long central corridor. To the right, behind glass walls, designers and engineers gather around technical drawings. To the left is a production floor lined with five CNC machines and other machine tools. Farther inside are a prototyping room, a finishing department, a clean room for movement assembly, a quality-control room, a stockroom, and even a dedicated room housing a femtosecond laser machine. Not everything is made here. Cases and sapphire crystals, among other components, still come from outside suppliers. What Fam al Hut has built, however, is an environment in which it can control the design, prototyping, machining, assembly, testing, and continued development of its movements. For such a young independent brand, the scale of the operation was far beyond what I had expected. Fam al Hut was founded in 2024. The following year, its debut watch, the MARK 1 Möb...

Introducing: Panerai’s Luminor Marina PAM01707 Is All Classic Everything, Except For The High-Tech Composite Case

What We Know As one of the more recognisable watch designs, period, the current Panerai Luminor shape has been rendered in many different materials since the 1955 introduction of the crown protection device. This latest take, the Luminor Marina PAM01707, is cased in Carbotech, a composite material combining carbon fibre sheets and polyether ether ketone, resulting in excellent anti-corrosion properties and lightness. Though Panerai’s products now comfortably sit in the luxury watchmaking category, it hasn't stopped them from using avant-garde materials suited to the original intent of their designs. Measuring 44mm across and 14.5mm thick, the PAM01707 has all the hallmarks of a classic Panerai, with its cushion-shaped mid-case sandwiched by a round, striated Carbotech bezel and a DLC-treated titanium caseback. The signature bridge, which spans the right-hand side of the case and protects and locks the crown, is also rendered in carbon, matching the uneven, textured finish of the rest of the case. This sanga-based analogy can be expanded on for the dial, another Panerai hallmark. The textured, matte top plate features cut-outs for the stick indices and Arabic numerals at the cardinal points, as well as the small seconds indicator at 9 o’clock, allowing the fauxtinated Super-LumiNova bottom layer to shine through. Here pictured on brown calf leather, Panerai also includes an “Officine Panerai”-branded black rubber strap so you can actually take the watch swimming, th...

Luxury Look, Accessible Price: Why the Fossil Harwell is the Perfect Ralph Lauren Stirrup Alternative

A few years ago, my friends gifted me the Fossil Harwell ES5267. From the moment I opened the box, I was absolutely captivated. I have always loved the color green, especially when paired with gold, and this watch executes that combination flawlessly. But beyond its stunning colorway, it stands out for another reason: it is arguably the best affordable alternative to the luxurious Ralph Lauren Stirrup Small. If you love the quiet luxury and equestrian heritage of the Ralph Lauren Stirrup but can’t justify the designer price tag, the Fossil Harwell captures the exact vibe.  The Appeal of the Stirrup Shape The stirrup case design immediately draws the eye. Instead of traditional lugs, the strap typically passes through the upper loop of the case, integrating the watch seamlessly onto the wrist. It’s a silhouette that feels both vintage and contemporary, perfect for adding a touch of tailored elegance to any outfit. It is a bold, instantly recognizable case shape that acts as a piece of statement jewelry just as much as a timekeeper.  The Inspiration: Ralph Lauren Stirrup Small To understand the appeal of the Fossil Harwell, we first have to look at the titan that inspired this aesthetic: the Ralph Lauren Stirrup collection. Introduced at SIHH in Geneva in 2009, the Stirrup collection perfectly captures Ralph Lauren’s deep equestrian heritage. The Stirrup Small features an iconic stirrup-shaped silhouette, measuring 27.7 x 29.3 mm, and often houses high-end Swiss mov...

Kanoa Igarashi’s Fourth G-Shock G-LIDE Is Ready for Surf and Training WatchRider

Kanoa Igarashi’s Fourth G-Shock G-LIDE Is Ready for Surf and Training

Most surf watches stop after telling you when the tide is coming in. The new G-Shock G-LIDE GBX-H5600KI-5 also checks your heart, studies your sleep and expects you to catch the next wave. Casio has released its fourth signature watch with Japanese professional surfer Kanoa Igarashi. The GBX-H5600KI-5 is based on the heart-rate-equipped G-LIDE GBX-H5600, but its brown marbled body and soft purple details give it a look that is easy to separate from the standard models. A colour scheme inspired by Portugal The mixed brown colour is inspired by the cliffs and rocky coast around Ericeira, Portugal, one of Igarashi’s training bases. Casio mixes different colours of bio-based resin during production, so the streaks and marks will not be identical on every watch. That gives each example a slightly different surface pattern without pretending that the watch is hand-finished. The lavender details are a smart contrast to the dark case. A purple vapor-deposited finish around the display is meant to recall the sea during the early morning and evening magic hours. Igarashi’s signature sits below the screen and also appears on the back. His World Surf League competition number, 50, is printed on the lower part of the band. Built for the water, but useful away from it The case measures 51.1mm long, 44.5mm wide and 17.3mm thick. That is a large watch on paper, although 47 grams is impressively light for a G-Shock with an optical heart-rate sensor. The carbon-fibre-reinforced resin ba...
