Seiko freshens up its Seiko 5 field GMT with two new colours

When considering a highly functional, reliable, no-nonsense timepiece that doesn’t break the bank, Seiko 5 undoubtedly comes to mind. Seiko also changed the game for affordable complications when it released the Seiko 5 GMT in 2022, making mechanical dual-time watches accessible to a whole new audience. Seiko’s first foray into this territory took the form of the … Continued

Celebrating a New Home for Watch Enthusiasts in Eastern Montana with Citizen Watch America and Riddle’s Jewelers Worn & Wound

Celebrating a New Home for Watch Enthusiasts in Eastern Montana with Citizen Watch America and Riddle’s Jewelers

Last week, Worn & Wound and Citizen Watch America headed west to Billings, Montana, for an evening of watches, conversation, and a little bit of Windup Watch Fair previewing at Riddle’s Jewelry’s Shiloh location.  Following our enthusiast night in Salt Lake, the Billings event was another chance to bring the Windup experience to a community that doesn’t always get the opportunity to see this kind of collection of watches in person. But more than anything, the evening was about establishing Riddle’s Jewelers as a welcoming home for watch enthusiasts in Eastern Montana—and kicking off what we hope becomes a new tradition of getting together, talking watches, and, naturally, buying a few new timepieces along the way. The evening welcomed local enthusiasts, longtime collectors, curious newcomers, and Riddle’s clientele, all with one thing in common: an appreciation for a good watch and an excuse to talk about them. With food and drinks on hand, the evening had the easygoing feel we love about enthusiast gatherings. Watches came off wrists, new ones went on, and conversations bounced from movements and materials to personal favorites and the watches everyone had been quietly keeping an eye on. Of course, there was plenty to get excited about on the watch front. The collection included standout pieces from Citizen, Bulova, Accutron, Frédérique Constant, and Alpina, including several watches that aren’t exactly easy to find sitting in a display case. And our new ...

Hands-On: BA111OD’s Chapter 7 Skeleton Gets a Light and Airy Stainless Steel Build

I had heard the name but was not aware of the unforgettable spelling until I got a sample of my first BA111OD watch, the latest addition to the brand’s catalog: the Chapter 7 Skeleton. While BA111OD traces its roots back deep into the history of watchmaking, its modern incarnation has taken shape over the past seven years with several different chapters. One of the biggest evolutions we have seen in the brand’s contemporary catalog is in its movements. While early chapters got flack for keeping costs accessible with Chinese calibers, Chapter 3 incorporated the first Swiss caliber into the Swiss-based Maison’s lineup in 2022. The brand’s next installment, Chapter 4, continued to build on this trajectory with the BA111OD caliber BA.01. This movement was notably developed in collaboration with watchmaker Olivier Mory whose La Chaux de Fonds workshop has given rise to movements for brands across the industry, from Louis Erard to Yema. Then, BA111OD’s Chapter 5 went on to introduce the Maison’s first automatic chronograph thanks to the ETA Valjoux 7750. Next, Chapter Delta entered the lineup with a major shakeup thanks to another movement co-created with Olivier Mory, this time featuring a unique hypocycloidal mechanism. Instead of a standard central rotating hand, a satellite hour wheel rolls around a fixed central wheel. This creates a deltoid path where the hour dot naturally slows down and speeds up during its rotation cycle. Here, traditional circular minutes c...

Vacheron Constantin s 30th Anniversary Overseas Sep 24, 2026

Introducing: Vacheron Constantin's 30th Anniversary Overseas Perpetual Calendar Ultra-Thin Limited Edition

What We Know The hottest Vacheron Constantin collection is celebrating its thirtieth anniversary this year, and the brand is paying tribute with a new version of one of my personal favorite watches from the brand. Sure, earlier this year we got the return of the 2500V, which is celebration enough, but the new limited-edition azure blue Overseas Perpetual Calendar Ultra-Thin is a limited edition that honors the first generation of the collection. Below is a picture of the current third generation and the 1996 first generation, itself a successor of sorts to the 222 in 1977 and the 1975 Chronomètre Royal before it. Yes, Vacheron has done a blue version of this watch before—and has released a few other colors recently, including a bold red—but now the same 41.5mm by 8.1mm white gold case gets a more muted, less saturated azure blue soleil and lacquer treatment, with white and light blue printed text and applied indices with Super-LumiNova. The movement is the same Caliber 1120 QP/1 automatic movement that is only 4.05 mm thick. Yes, other brands are slowly introducing perpetual calendars with a crown-adjustment system, but while this still uses caseband pushers, the benefit is a watch that measures 1.5mm thinner than the similarly wide Audemars Piguet Royal Oak. The watch runs at a slightly slower 2.75 Hz and has only 40 hours of power reserve, but again, at the thin profile you get, the wearability should more than make up for any small downsides. Another huge benefit i...

Introducing - Breguet Updates its Marine 5517 and Marine Chronograph 5527 with More Refined Dials

While Breguet is mostly known for its classic watches adorned with guiloché dials and the numerous inventions of its founder, Abraham-Louis Breguet, the venerable manufacture nevertheless holds two sportier collections: one intended for aviation (the Type XX), the other for naval exploration (the Marine). And both are actually inspired by important historical moments in the […]

Audemars Piguet Brings Padel to Singapore SJX Watches

Audemars Piguet Brings Padel to Singapore

Audemars Piguet is hosting a Padel Pop-Up Club starting September 25, marking the brand’s first local event tied to its involvement in the sport. Held in the School Hall of New Bahru, a fashionable “lifestyle destination”, the event will combine padel sessions with a courtside lounge, welcoming experienced players and newcomers. Padel, like its American counterpart pickleball, is a fast-growing racquet sport that blends elements of tennis and squash. Usually played in doubles, the sport is synonymous with the social atmosphere that surrounds it. Recognising this, Audemars Piguet is hosting a courtside lounge to welcome those who are more interested in the social scene than scoring points on the court. Audemars Piguet formally got involved with padel back in May, announcing a global partnership as official timekeeper of the Qatar Airways Premier Padel Tour, alongside sponsorship of Agustín Tapia, one of the sport’s top players. The tour agreement includes courtside clocks and branding at tournaments. While major sports like tennis, golf, and Formula 1 are saturated with watch brand partnerships, emerging sports like padel represent something of a Greenfield opportunity, especially with a younger audience. But that’s changing as brands adapt the well-established sponsorship playbook to the new domain. Earlier this year, Rolex added Spanish padel star Arturo Coello to its circle of celebrities, and Frederique Constant became the official watch partner of the Pro Pa...

First Look - Vacheron Constantin Celebrates 30 Years of Overseas Special Edition Perpetual Calendar Ultra-Thin

The story of the Overseas begins in 1977 with the sporty-chic integrated 222, Vacheron Constantin’s bold response to a new generation of luxury sports watches represented by the Royal Oak and the Nautilus. Inheriting certain traits of the 222 but amplified and beefed up, the first-generation Overseas debuted in 1996. Now in its third phase, […]

Hands-On Review: Going Green With IWC’s Ingenieur 42 Green Ceramic

IWC went green this year with the Ingenieur 42 Ceramic, and while we thought the black was good, this could be better! What We Love: The shade of green ceramic works extremely well The gold accents elevate the watch nicely The finish & light play make this a standout on the wrist What We Don’t: Still, the lack of the quick-link adjustment system on the bracelet The 42 mm case size may not suit all wrist sizes and types A full ceramic watch may not be for everyone, or suit some people’s lifestyles Overall Rating: 8.75 / 10 Value for Money: 8.5/10 Wearability: 8/10 Design: 9.5/10 Build Quality: 9/10 When IWC released the black ceramic Ingenieur last year, I was pretty impressed with how well the watch worked in the metal, or ceramic, I should say. The Ingenieur is already a very distinctive design, and creating it in ceramic could easily have changed the proportions or feel of the watch, but IWC managed to retain what makes the current Ingenieur work while giving it a completely different feel on the wrist. IWC CEO Chris Grainger-Herr talked to us about this last year, and how much research and development went into making a 42mm-sized ceramic version to mirror the proportions, look and feel on the wrist as the standard steel 40mm. It was an interesting chat, which you can read all about here. It’s not easy being green, as the frog once said! But maybe, in this case, it is! Not content to rest on its laurels, IWC released a green ceramic version for Watches & Wonde...

H. Moser & Cie.’s Off-Grid Bares All SJX Watches
Breitling Aerospace debuted more than Sep 23, 2026

H. Moser & Cie.’s Off-Grid Bares All

Following last year’s Streamliner Alpine Mechanics Edition made for the Alpine F1 team, H. Moser & Cie has just released its second smartwatch, this time with a unique take on the genre. The Off-Grid offers a streamlined set of programmed complications designed to occupy in the space between a mechanical watch and a smartwatch. In doing so, the Off-Grid eschews common functions like health tracking and notifications, allowing its full feature set to be accessed with or without a smartphone connection. The offline theme explains its most unusual complication, a built-in dictionary of 10 words in each of 21 different languages. Initial thoughts At first glance, the 1980s-style ana-digi display may feel more at home in a G-Shock or Seiko ‘Arnie’ than a Swiss luxury watch, though Moser is hardly the first Swiss brand to give the format a go. The Breitling Aerospace debuted more than 40 years ago, and Omega later introduced the ana-digi Speedmaster X-33 in 1998. But unlike the aforementioned, Moser’s choice to put the module on show beneath a semi-open-worked dial is a unique approach and reveals the brand’s mechanical watchmaking instincts. With the Off-Grid, Moser is trying to find the middle ground between mechanical and electronic watchmaking that offers the benefits of both worlds but without all the downsides — like constant notifications and fast-draining batteries. The “Off-Grid” moniker sums up the effort, both in terms of its autonomy and its conceptua...

Hands On: Blancpain Lady B SJX Watches
Jaeger-LeCoultre cal 101 which Sep 23, 2026

Hands On: Blancpain Lady B

The charming and compact Lady B extends Blancpain’s collection of elegant ladies watches while upholding the brand’s longstanding commitment to mechanical calibres. At just 19 mm in size and almost spherical in form, the Lady B contains an upmarket automatic movement that transcends the quartz-powered norms for this segment of watchmaking. Initial thoughts The Lady B is the spiritual successor to the Ladybird Bullet, which introduced the world’s smallest round mechanical movement when it debuted 70 years ago under the leadership of Betty Fiechter, the first woman to lead a major Swiss watch brand. The “round” qualifier is important because the smallest mechanical movement — then, as now — was the Jaeger-LeCoultre cal. 101, which is still in production but in extremely limited numbers, and reserved for high jewellery collections. The Lady B (left) with the original Ladybird Bullet from 1956 The Lady B is larger than the vintage Bullet, but at just 19 mm it’s still small enough that the size is the main point of intrigue. The watch is almost spherical being 13 mm thick, but rather than feeling too thick this aspect gives the watch a charming bead-like feel similar to the original Bullet. The spherical feel is completed by the absence of conventional lugs; the Lady B instead features a pass-through channel for a selection of interchangeable straps. This hypothetically allows multiple Lady B’s to be “stacked” on the same strap for a jewellery-like look, b...

Introducing: Marathon x Watches of Espionage Titanium SAR Hodinkee

Introducing: Marathon x Watches of Espionage Titanium SAR

What We Know Marathon Watches, the Canadian watch brand best known for its line of military-issued and -inspired watches, and Watches of Espionage, the online journal that has made a name for itself exploring the very tangible connection between watches and militaries around the world, have teamed up to launch a new watch that's sure to grab attention: The Marathon x W.O.E. Titanium SAR. The new watch, which officially launches this Thursday, includes a host of firsts for both Marathon and Watches of Espionage. For Watches of Espionage, which launched five years ago and is run by a secretive (some might say "sketchy") former CIA Case officer, the Marathon x W.O.E. Titanium SAR is a first venture into the world of collaborative watches. For Marathon, the fourth-generation family-run company with a slightly longer history than Watches of Espionage, the Marathon x W.O.E. Titanium SAR is the brand's first foray into titanium watches. On the surface, the new watch won't seem like much of a departure for Marathon, especially to those familiar with the brand's past offerings. The new watch draws heavily on the original Marathon SAR, first released in 2001, but modernizes the package and brings Grade 5 titanium to the table for the first time. Like other SAR watches from Marathon (such as the GSAR, TSAR, or OSAR-D), the new watch measures 41mm across, 48mm lug-to-lug, and 14mm thick, with much of that thickness coming from the toothy bezel. Just because this watch feels familiar d...

Since 2014, the Omega Speedmaster Professional has used exceptionally long reference numbers (also referred to as the PIC14 system).

Officially, it was eight digits (3570.50.00), but, as most collectors […] Visit Guide: Omega Speedmaster Reference Numbers Explained to read the full article.

Sotheby’s Sets Record Price for Cartier and Quartz SJX Watches

Sotheby’s Sets Record Price for Cartier and Quartz

The Cartier Cheich is one of the jeweller’s most unusual, and rarest, creations. Originally conceived as a prize for winners of the Dakar Rally during the years when the race was sponsored by Cartier, the Cheich was modelled on the rally’s emblem that is a stylised bust of a Tuareg tribesman wearing a headscarf – cheich is French for “sheikh”. Four originals in yellow gold were made, and amongst the recipients were Thierry Sabine, the founder of the Paris Dakar Cartier Challenge, and Gaston Rahier, a driver who won the rally in 1984 and 1985. Sabine’s death in 1986 put an end to Cartier’s sponsorship of the rally. Rahier’s watch was sold by Sotheby’s in 2022 for a little over €1 million with fees. But some 25 years after the original Cheich watches were made, Cartier made one more, in white gold no less. And that watch just sold for US$3.38 million including fees at Sotheby’s stellar Hong Kong auction, making it the most valuable Cartier watch ever sold publicly – and also the most valuable quartz watch ever sold. The result underlines the continuing demand for distinctive Cartier form watches, a category that includes the iconic Crash. The Cheich in white gold was originally commissioned by Giorgio Seragnoli, an heir to an Italian packaging dynasty who was once owned the world’s largest collection of Cartier timepieces, primarily wristwatches in white metals. A native of Bologna, sMr Seragnoli unfortunately exhausted even his considerable fortune...

Insight: Screw-Down Showdown SJX Watches
Omega Speedmaster Moonwatch Sep 22, 2026

Insight: Screw-Down Showdown

Mechanical movements attract most of the technical interest in watchmaking, but considerable engineering also goes into keeping them dry. For an everyday watch, the waterproof construction of the case and crown is central to its reliability, yet the way these components keep water out is often misunderstood. Screw-down crowns and case backs are widely regarded as the best way to seal a watch. But the choice is not always straightforward. On a hand-wound watch, for example, a screw-down crown must be unscrewed and tightened regularly, adding an extra step to winding and potentially compromising the threads. The Omega Speedmaster Moonwatch, on the other hand, features a conventional crown and is rated to 50 m. Even so, some owners remain wary of exposing it to more than an occasional splash. So the question is, how much protection can a conventional crown provide, and what does a screw-down construction add? To understand the distinction, we take a closer look at the crown, its tube and the gaskets that form the seal. As a disclaimer, this discussion concerns modern watches with seals in good condition; vintage watches and those long overdue for service should be checked for waterproofness prior to contact with water. A common misconception The actual waterproofness of a joint relates to the uniformity of the seal pressure. In this case, “waterproofness” is used broadly as the ability of a mechanical joint to keep water from seeping in under normal functioning conditions...

Grand Seiko Elegance SBGW325 Arabic Blue Sep 21, 2026

Introducing: Grand Seiko Elegance SBGW325 'Arabic Blue' Limited Edition

What We Know It's likely that very few people, save the Grand Seiko diehards, remember the first manually winding 9S caliber in the GS collection. A distinction within a distinction, it did set the stage for a number of deeply loved models and the eventual development of one of my favorite movements, the relatively recent 9SA4. But back in 2001, Grand Seiko launched the SBGW003, a relatively simple-looking watch with an opaline white dial and distinctive applied gold numerals. It might seem a bit anachronistic, but that's why Grand Seiko is honoring the 25th anniversary with a very modernized homage, the Elegance SBGW325 'Arabic Blue.' To be fair, the new SBGW325 looks so much newer because the original was also a tribute to the past, furthering the aesthetic divide. Now, the watch features a deep navy blue dial inspired by Japan's indigo craft heritage, with silver-toned hands and indices, including the distinctive applied numerals to honor the original. There's also a touch of gold, a reference to the original indices, I'd imagine, with the central seconds hand and GS logo. The serif on the numerals seems to have been softened a bit as well. The Zaratsu-polished stainless steel case measures 37.3mm by 11.7mm with a 44.3mm lug-to-lug, capped by a box-style crystal. The watch is limited to a 30m water resistance but comes with a display caseback through which you can see the 9S64 caliber movement. That gives a 72-hour power reserve running at 4Hz. But overall, the watch ma...
