Zenith Goes Back to Basics with Its First Time-Only Chronomaster Worn & Wound
Zenith Goes Back Sep 2, 2026

Zenith Goes Back to Basics with Its First Time-Only Chronomaster

Since its inception in 1969, Zenith’s groundbreaking El Primero movement – the first automatic, integrated, high-frequency chronograph caliber – has been synonymous with the classic complication. Now, Zenith takes the essence of this historically significant movement and highlights the high-frequency component with its first time-only application in the Chronomaster line. With the new Chronomaster Solo Sport, form and function go hand in hand. The three-hand display offers a design that is decidedly less sporty than its chronograph counterparts. However, the new collection continues a throughline we’ve seen within the Chronomaster lineup, making it both fresh and familiar to the model family. The Solo Sport has a 40mm build that fits well within the Chronomaster range of 37mm for the vintage-inspired revival models up to 41mm for the standard chronograph sport models. As we’ve also seen in the typical sport models, the Solo Sport models feature a ceramic, unidirectional rotating bezel. Ceramic extends to the dial, which presents a new “Z” pattern. Depending on the version – white, black, or brown – this pattern is engraved on either a sunray-finished white ceramic dial or a polished black or brown ceramic surface. Additionally, the black version is also offered in a no-date variant for a total of four Solo Sport styles. The “Z” motif is repeated once more on the stylization of the seconds hand. The more geometric elements of this dial design continue ...

Biver Debuts a Most Sophisticated Micro-Rotor Calibre SJX Watches

Biver Debuts a Most Sophisticated Micro-Rotor Calibre

Founded by the namesake father and son duo, Biver has just debuted its second model, the Biver Automatique. Though a simple a time-only watch with central seconds, in contrast to the preceding Carillon Tourbillon, the Automatique is equipped with an elaborately executed movement that’s arguably the most impressive recent automatic. Besides decorative touches like guilloche on the bridges, the JCB-003 also features details like a grande sonnerie-style winding click. The calibre is paired with a comparably elaborately constructed dial with solid gold appliqués that’s available in a variety of materials, including mineral stone like Pietersite. The JCB-003 Initial thoughts The Automatique is clearly meant to showcase the brand’s ability to create a highly finished and refined time-only watch that can compete with more established producers, both in terms of the movement as well as habillage (namely the dial and case). The highlight of the Automatique is the JCB-003 movement. Developed in partnership with movement specialist Dubois Depraz, the JCB-003 is quite possibly the most refined micro rotor movement on the market today. Though it is functionally simple, the movement boasts decorative and technical details along with a high level of finishing. The over-engineered caliber is meant to serve as a base for future complications, which makes sense considering the high cost involved in constructing such a movement. Amongst the calibre’s notable details is the grande so...

New Steel Omega Speedmaster 321 “Ed White” Just Announced (ref. 311.30.40.30.01.001)

Omega has delivered on what the Speedmaster community has been demanding for a while now. The big difference between the previous Omega 1863 Caliber and the new Omega 321 Caliber is that the 321 has a column wheel actuator for the chronograph. This is in contrast to the 1863 Caliber's cam-actuated chronograph function.

Industry News: Ronda Returns to Mechanical Movements with the Impressive R01

Typically, not a lot happens in the world of third-party mechanical watch movements. The ETA2824 reigned supreme for decades until Swatch Group stopped openly supplying them, giving way primarily to Sellita, Soprod, and La Joux Perret on the Swiss side, and Miyota and Seiko on the Japanese side. For the most part, the catalogs of those brands stayed relatively unchanged for many years, but now, it appears that there’s a bit of an arms race happening. The days of 42-hour power reserves are over, and brands are now vying for features and specifications once limited to more expensive calibers; to that end, there have been a series of interesting events/releases. First, the COSC announced the creation of the “Excellence Chronometer” standard with a -2/+4 accuracy standard among other considerations. Sellita launched the SW200-2 Power + movements with 65-hour reserves, new gear trains, and other improvements. The CEO of La Joux Perret spoke about the upcoming G-200 caliber, which will feature a 72-hour reserve and antimagnetic properties, on the Hodinkee podcast. And this week, a very exciting new automatic was announced by a surprising source: Ronda. The R150 launched in 2016 Ronda is a well-known Swiss manufacturer that was founded in 1946. Over their 80 years of existence, they have specialized in many things, from component manufacturing to ebauchés and full mechanical movements to, beginning in the 1970s, quartz calibers, which is what they are best known for today....

Introducing: The Zenith G.F.J. Calibre 135 Double Signed with Naoya Hida & Co Hodinkee

Introducing: The Zenith G.F.J. Calibre 135 Double Signed with Naoya Hida & Co

What We Know Today, Zenith introduces a new "Double Signed" program for its Calibre 135-powered G.F.J. collection, and its first entry in this series is a collaboration with a Japanese independent that might not require all that much introduction around these parts—Naoya Hida. The evolution of the G.F.J. line has not taken all that long, with its origins starting in 2022 with the Zenith Caliber 135 Observatoire Limited Edition, where ten Calibre 135 movements from the 50s were restored by Kari Voutilainen and introduced in watches done as a triple collaboration between Zenith, Voutilainen, and auction house Phillips. Just three years later, the Calibre 135 was revived as a modern caliber for a line called the G.F.J. (after Zenith's founder Georges Favre Jacot). In just a little over a year, we've seen three small runs of this watch introduced in different stone-dial and metal combinations—platinum with a lapis lazuli dial, tantalum with an onyx dial, and an upcoming yellow-gold GFJ with a bloodstone dial. In the meantime, this new Double Signed concept with Naoya Hida takes the G.F.J. in a very different visual direction. The hefty 39.15mm platinum case, with a thickness of 10.5mm and a compact lug-to-lug of 45.75mm, remains the same as other G.F.J. models. But that dial is unabashedly Naoya Hida, constructed out of solid silver with the distinctive hand engraving coming from the hand of master engraver Keisuke Kano, the man responsible for the hand engraving across al...

Introducing: The Patek Philippe 5322G Brings A More Modern-Sized And Styled Chiming Alarm Function To The Catalog (Live Pics)

What We Know Unveiled as part of a slew of new releases for Watches and Wonders 2026, the Patek Philippe 5322G offers a chiming 24-hour alarm complication in a modern case and design, with a new movement and a slightly smaller size than the discontinued model it replaces. The watch is housed in a white gold 41mm Calatrava case that's 12.22mm thick and features hollowed-out lugs, the brand's signature 'Clous de Paris' or "hobnail" guilloché pattern on the case middle, and a single pusher at 2 o'clock. The alarm is programmed through the pusher, and it can be set via the crown in the second position, which the brand says works "intuitively."  With a water resistance of 30 meters, Patek says the new 5322G is the only water-resistant chiming watch in the current collection. The new model replaces the Ref. 5520 Pilot Alarm Travel Time, which debuted in 2019 and was inspired by an historical aviator watch in the Patek museum in Geneva. Photo courtesy Patek Philippe. The model continues Patek's modern Calatrava style with a textured, lacquered dial in green or blue. The applied Arabic numerals and white-gold, syringe-style hands are both filled with luminescent material, adding to the contemporary feel. A hand display date sits at 6 o'clock, while the double-window aperture of the alarm function sits above the handset at 12 o'clock. Powering the 5322G is the new self-winding AL 30-660 S C caliber that chimes the alarm with a single hammer striking a classic gong around the case...

Watches & Wonders: the Nomos Tangente neomatik 38 Update Brings the Date Ring and the Midas Touch to a Smaller Size Worn & Wound
Nomos Tangente neomatik 38 Update Apr 13, 2026

Watches & Wonders: the Nomos Tangente neomatik 38 Update Brings the Date Ring and the Midas Touch to a Smaller Size

In the Nomos Glashütte lineup, the Tangente is one that brings it all: the allure of 18-karat gold, sizes that range from 33 to 42mm, a unique and subtle date ring, even a few models rated to 1,000 feet of water resistance.  Now the most popular features merge into one aptly-named release: the Tangente neomatik 38 Update, making its debut at this year’s Watches & Wonders. It begins with the mid-sized case that measures 38.5 millimeters, hitting the sweet spot of popularity and balanced proportions. And it’s now available in 18-karat gold, alongside the stainless steel seen on most Tangente models.  “By introducing Tangente Update in gold,” says Nomos CEO Uwe Ahrendt, “we are also responding to a frequently heard request for modern dress watches, crafted from precious metal.”    The most important feature in this new model is adapting the date ring into a smaller format. The date ring, which Nomos calls Update, circles the edge of the dial with oval windows marking the days of the month, indicating the current date with two red markers on either side.  Previously, the date ring was formerly only available in a 41mm size, or in an unusual two-date system that debuted in 2024. What’s under the skin and behind that 18-karat gold case is the neomatik caliber DUW 6101: an automatic-wind movement with up to 42 hours of power reserve that now gets the same date ring system adapted into a smaller size (just 7.4mm in height, a squeak below the 7.8mm size of the ...

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 ...

The 2026 Winter Olympics are 100 Days Away, and Omega Has a New Speedmaster to Celebrate

It’s that time again. The air is getting crisper, the days are getting shorter, and, for better or for worse, the realization that winter will soon set in is becoming more and more real. If you’re like me, and dread fighting snowy streets and icey…everything, this is a less than exciting time. But if you’re Omega? Well, that’s a different story. They are in countdown mode to the 2026 Winter Olympics in Milano Cortina, and they’ve just released a new Speedmaster to mark 100 days from the start of the games.  The Speedmaster Milano Cortina 2026 is built on the 38mm Speedmaster platform, and comes in a stainless steel case that measures 14.75mm tall. The dial is evocative of the snowy mountains that will be the setting for the games for next year, with a varnished white surface and subtle blue accents that evoke the Milano Cortina 2026 logo. The blue ceramic bezel and blue CVD coated hour markers keep the theme coherent and appropriately wintery. Another nice detail is that the chronograph hand has a gradient finish, going from light blue at its base to dark blue at its tip. Also, when the date window shows the 26th of the month, it does so in the typeface of the Milano Cortina logo.  The Speedmaster Milano Cortina 2026 runs on the Caliber 3330, an automatic movement with over 50 hours of power reserve and COSC certification. This, of course, is not a traditionalist’s Speedy, but more akin to the “Reduced” models of an earlier era. The 38mm size is easy to...

15 Best Purple-Dial Watches From Affordable to Luxury

Purple is the color of royalty, and it appears that a Purple Reign has started to quietly take over the watch world in recent years, with violet hues finding their way to an increasing number of dials, from a somewhat surprisingly diverse range of watch brands. Like their predecessors in green, red, and orange, purple dials are still, in fact, something of a novelty; many of the timepieces featured below are intended for a niche, limited audience. Nevertheless, the rise of purple tones on watch dials is worthy of notice, and almost certainly here to stay for a while, Here we’ve gathered 15 of our favorite purple-dial watches in ascending order of price, from under $500 to over $85K. Citizen Tsuyosa Automatic Sunray Purple Dial Price: $475, Case Size: 37mm, Water Resistance: 50 meters, Crystal: Sapphire, Movement: Automatic Caliber 8210 Best known for its light-powered Eco-Drive movements, Japan’s Citizen also offers a lineup of mechanical timepieces, including the NJ015 automatic series, nicknamed “Tsuyosa,” a Japanese word meaning “strength.” Speaking to the contemporary trend towards eye-catching colorful dials, Tsuyosa models offer a variety of them, with a subtle sunburst finish, including the purple dial watch above. The round, chamfered steel cases measure 40mm in diameter and 11.7mm thick, with an unconventionally positioned crown at 4 o’clock for better ergonomics on the wrist. The bracelet has what Citizen describes as a “mountain-shaped” design ...

From the Seiko SKX to the SPB317: How I Fell in Love with Seiko Again Worn & Wound

From the Seiko SKX to the SPB317: How I Fell in Love with Seiko Again

At the end of summer 2014, Dad gave me my first mechanical watch. There was nothing ceremonial about it; he simply handed me the box in the car. “I’m starting a new tradition, and it’s a grown-up gift since you’re heading to college,” he said. I looked down at the box. It said Seiko. I was familiar with the brand. In fact, it was what I had been wearing up to that point: reference SNE039, a mid-sized solar-powered watch that Grandpa gave me when he saw me showing interest in it. I still have it. But this Seiko was different. It was a reference SKX173, a sibling of the beloved SKX007 dive watch that has led many a good man down the rabbit hole. It had a waterproof case, rotating dive bezel that I had no clue how to operate, and most importantly, an automatically winding movement.  “It’s easy – just shake it a bit to get it going,” said Dad. (OGs will remember the caliber 7s26’s lack of hand winding). I took the watch out of the box and shuffled it back and forth gently to coax it to life. It did, and as I stared at the sweeping seconds hand, I marveled that a microscopic team of gears, levers, and springs were all working harmoniously just to tell time. As an incoming engineering student, I couldn’t have asked for a better gift. I secured the black rubber strap on my wrist, and that was that. The remainder of the summer was spent reading everything I could get my hands on about Seiko watches and mechanical timekeeping at large. The excitement of movin...

Hanhart and German Magazine Armbanduhren Unveil a Limited Edition Preventor HD12 in Purple Worn & Wound

Hanhart and German Magazine Armbanduhren Unveil a Limited Edition Preventor HD12 in Purple

I’ve long had a contentious relationship with the color purple; between youth softball teams and grad school alma maters, it’s always difficult to find anything to wear with the color that isn’t immediately clashing. But purple is also a color associated with luxury and royalty, so I am approaching the new Silk Purple Hanhart Preventor HD12, a collaboration with German watch magazine Armbanduhren, with an open mind.  Hanhart’s Preventor HD12 was originally launched in August 2024, and has fast become one of the Swiss-German brand’s most popular pieces. A field watch-style dial design paired with HD12 scratch-resistant steel, and powered by a Sellita caliber SW200-1 or Soprod SOP P024 automatic movement, the Preventor combines the vintage styling that Hanhart is known for with robust construction and durability.  With easy-wearing case dimensions of 39mm in diameter and 46mm lug-to-lug, the Preventor positions itself as an everyday timekeeping watch with few complications-even lacking a date window. The HD12 steel is made scratch-resistant through a multi-stage hardening process, in which carbon is diffused into the steel and the case is covered in an additional PVD coating. Hanhart continues to tout the “hardness” factor of the Preventor by protecting the dial with a scratch-resistant convex-curved sapphire crystal.  Of course, the dial is where the fun happens for this limited edition Preventor. The matte Silk Purple contrasts starkly with the white Ara...
