Girard-Perregaux Introduces the New Minute Repeater Flying Bridges Worn & Wound
Vacheron Constantin released Mar 12, 2026

Girard-Perregaux Introduces the New Minute Repeater Flying Bridges

And just like that, it’s Super Watch Season. Every year we see a handful of watches that come to market that exist for the purpose of displaying the absolute pinnacle of what a brand can accomplish. Think of ultra complicated watches from Vacheron Constantin released in recent years, or pieces from Greubel Forsey focused on extravagant hand finishing and machining. The new release from Girard-Perregaux feels like a member of this rare category.  The new Minute Repeater Flying Bridges combines a tourbillon and a minute repeater with GP’s famous “Three Bridges” movement architecture. The highlight here, beyond the rarity of a repeater, is that the new Calibre GP9530 is a self-winding movement (via a micro-rotor), which is exceedingly rare among chiming watches and, to a lesser extent, tourbillons.  Girard-Perregaux has a long history in chiming watches that dates back to the 1820s, and the Minute Repeater Flying Bridges is fashioned as a tribute to those earliest repeaters, while being unapologetically contemporary in its design. Certainly part of that tribute is in the craftsmanship itself, and in the use of the most modern technology available to create the best chiming mechanism possible. To that end, the movement has been radically skeletonized not only for aesthetic reasons but to prioritize resonance. According to the brand, every technical choice made in the development of the new watch was made in the name of optimizing the sound of the chime. For a repeat...

Breitling Introduces The Stylish Reverse-Panda Superocean Heritage B01 Chronograph 42

One of my all-time favorite chronographs is the Breitling Top Time ref. 810. It’s a stunning classic hailing from a long line of legendary reverse-panda chronographs that Breitling produced in the ’50s and ’60s. I could easily create a list of 5–10 of my Breitling favorites from that era, so when the brand announces a […] Visit Breitling Introduces The Stylish Reverse-Panda Superocean Heritage B01 Chronograph 42 to read the full article.

In-Depth – Girard-Perregaux’s Superbly Technical New Minute Repeater Flying Bridges (Incl. Video)

Few timepieces showcase the technical sophistication of traditional watchmaking as clearly as minute repeaters. The new Girard-Perregaux Minute Repeater Flying Bridges introduces this complication with its demanding mechanism, combined with a tourbillon and an automatic micro-rotor winding system. The watch is built around the brand’s recognisable Three Bridges architecture, presented in a modern openworked interpretation […]

Highlights: Independent Watchmaking at Marteau & Co SJX Watches

Highlights: Independent Watchmaking at Marteau & Co

After its successful indie-focused First Strike auction last October, upstart auctioneer Marteau & Co is back with The Echo, an online-only auction that opens at noon Geneva time on March 12 with a focus on independent watchmaking. Marteau & Co was founded just last year, and one of its cofounders is Arthur Touchot, an industry veteran who spent several years as a journalist followed by a stint at a prominent auction house. Now all-in with Marteau, Mr Touchot brings his insider’s to Marteau, explaining its unique position in the market. The Swiss auctioneer sets itself apart with its intriguing “Maker’s Fee” concept, which rewards the maker of the timepiece with 3% of the hammer price for each watch sold, allowing a brand to benefit from the appreciation of its products. While artists’ resale rights, or droit de suite, is far from a new concept, and has been codified into law in the European Union and United Kingdom, Marteau & Co’s approach is the first instance of its application in watchmaking. Lot 1 – Daniel Roth Chronograph Ref. 2147 When Daniel Roth launched his eponymous brand in 1988, after helping revitalize Breguet, he also created the genre of independent watchmaking we know today, preceding even Franck Muller and F.P. Journe. With his double ellipse case design Roth pioneered the idea of building a brand around a single strong design language, a contrast to the menagerie offered by other high end brands of the time, an approach later followed by ot...

Parmigiani Fleurier Introduces the Tonda PF Automatic 36mm Alta Rosa Worn & Wound
Parmigiani Fleurier Introduces Mar 11, 2026

Parmigiani Fleurier Introduces the Tonda PF Automatic 36mm Alta Rosa

As Watches & Wonders approaches, I find myself thinking back to last year’s fair and the various high and lowlights from that crop of releases. I’ve commented before about a pretty big highlight of last year’s show being Parmigiani Fleurier’s output, particularly their very strong Toric perpetual calendar. This is one of those watches that I rarely go a week without thinking about, like the woman in the white dress that Bernstein remembers from the ferry in Citizen Kane.  Anyway, Parmigiani is always a fun meeting at Watches & Wonders and my expectations are high after last year. In what I imagine will be their last release before the show next month, the brand has just introduced a new pink colorway to the Tonda PF line in 36mm. I’m not sure if we can consider this a preview of things to come (honestly, we probably can’t) but it’s a strong release nonetheless further bolsters the Tonda PF platform as an important player in the integrated bracelet sports watch landscape.  The new Tonda PF Automatic 36mm Alta Rosa brings a lighter dial color to the steel version of the 36mm Tonda PF for the first time – previously this watch had been available in blue and two shades of gray. Pink dials of course are often associated with watches targeted toward a female clientele, but hopefully the greater watch collecting community has moved beyond these types of prohibitive norms around gender and watch preferences. This is a really attractive color that can be worn by a...

Kollokium’s Projekt 02 Variant B Treads New Terrain SJX Watches
Louis Erard managing director Manuel Emch Mar 11, 2026

Kollokium’s Projekt 02 Variant B Treads New Terrain

Having teased its newest collection with a family and friends edition last year, Kollokium has finally taken the wraps off the Projekt 02 Variant B, which offers a low-profile die-cast stainless steel case and a terraced topographical dial. A massive box-form crystal contains the scene, offering a panoramic view of the 67 pieces that comprise the nine layers of the dial. A limited edition of 399 pieces, the Variant B is a well-priced entry point to the world of independent watchmaking, and could easily be worn daily. Initial thoughts Kollokium is a relatively new name in independent watchmaking, but the company’s three founders, collector Amr Sindi, designer Barth Nussbaumer, and Louis Erard managing director Manuel Emch, bring a trained eye and a fresh perspective to the brand. With a strong emphasis on design, underpinned by a simple but competent calibre, Kollokium seems to have mastered the game of trade-offs required to market a distinctive watch at an affordable price. Left to Right: Amr Sindi, Barth Nussbaumer, Manuel Emch. The Variant B is fundamentally a simple time-only watch, powered by an off-the-shelf La Joux-Perret cal. G101, an increasingly common base movement prized for its economy and autonomy, with a healthy 68-hour power reserve. But Kollokium’s watches are anything but ordinary, owing to the brand’s unusual dial treatments and case processing. The Variant B is technically the first publicly available version of the Projekt 02, which debuted last ...

Hublot regularly makes headlines. Most of the time, however, these headlines revolve around marketing and branding. A new superstar ambassador or a crazy limited edition is more likely to generate exposure than pure watchmaking prowess. Now, in part, this is down to Hublot’s doing. The house focuses on being radical, and it doesn’t mind stepping […] Visit Talking In-House Movement Manufacturing With Hublot’s Chief Product Officer, Sadry Keiser to read the full article.

Meet The Third Iteration Of The BND Dive Watch

We’ve been following the horological adventures of Vincent Bonnaud (1991, France) since 2021, when he introduced his first BND dive watch.

Vostok Amphibia Review: The $70 Russian Dive Watch With Global Appeal

The Vostok Amphibia has long been recognized by in-the-know enthusiasts as one of the most affordable yet reliable dive watches on the market, as well as one that retains a quirky appeal like no other, owing both to its origins in Soviet Russia as well as its more recent turn as a character-defining prop in a cult-classic Wes Anderson movie. Here’s everything you need to know about the Vostok Amphibia and a brief hands-on review of one of the current models.  [toc-section heading="Russia’s Watchmaker: Chistopol Watch Factory"] The backstory of the Vostok Amphibia is one that is winding and complex, and it actually can be traced back not only as far as World War II Russia but even farther, to the Hampden Watch Company of Canton, Ohio. In 1930, the bankrupt Hampden sold its machinery, equipment, and technical designs to the First State Watch Factory, soon to become the First Moscow Watch Factory, founded in Russia (then the Soviet Union) on the order of Joseph Stalin. It was the nation’s first state-owned manufacturer of watches and mechanical movements. With Nazi Germany’s army advancing on Moscow in 1941, the factory was evacuated to Chistopol, a town in Tatarstan on the banks of the Kama River. The renamed Chistopol Watch Factory produced not only watches and movements but also equipment for the Soviet military, both during the war and in the decades afterwards. Chistopol Watch Factory became the official watch supplier of the USSR Ministry of Defense in 1965 and...

Ming Watch Brand Review: Independent Watchmaking With A Decentralized

When it comes to luxury watches, rarely is a timepiece experienced on the wrist before it is admired through a lens. Horological photography has evolved so much that high-resolution imagery and macro-cinematography have become a virtual loupe, portraying the watch’s qualities and character through focus stacking and special lighting. For brands like MING, the photograph is the primary medium of truth, since the founder of the company is a world-class photographer. Ming Thein spent years dissecting the world’s finest timepieces through the lens of a camera. Before long, he became one of the industry’s most respected photographers, forming an obsession with light and how it behaves on the surface of a watch. Since building his own brand, Ming Thein has continued to nurture this special relationship between timekeeping and imagery, so much so that it has become part of the brand’s unique story. Every curve of a flared lug or inverted lume track on a dial is designed to catch, bend, and manipulate light – a philosophy that has translated into a string of global successes, including the "revelation" of the 17.06 Copper and the 2024 GPHG-winning 37.09 Bluefin. [toc-section heading="The Brainstorm That Gave MING Its Lift-Off"] Early concept sketch Plenty of business ideas have probably been dreamt up while racking up air miles, but the origins of MING were perhaps among the most unexpected.

Why the Plotter Notebook Cover Is One of the Best Refillable Leather Notebooks Worn & Wound

Why the Plotter Notebook Cover Is One of the Best Refillable Leather Notebooks

Look, I’m not going to say that I have all the answers here, people, but if there’s one thing I know how to spot, it’s a good notebook. While taxes may send me into a tailspin and I enter a fugue state any time that I’m forced to load the dishwasher, I can confidently say that if you want your notes written down and you want to carry around something that’s aesthetically pleasing…well, I’ll humbly say that I’m your guy for the right answer. Partially, my knowledge of notebooks is collateral damage because of my job – it doesn’t take a rocket scientist (or even someone who knows how to load a dishwasher) to see a job in pens has given me a deep understanding for what one writes with as much as what one writes on. To this effect, I have a general knowledge of the pros and cons of legal pads versus Moleskines, washi tape versus Scotch. But that stuff can be found fairly easily – Reddit, for better or worse, is a gold mine of information on stationery. But the other reason I find myself knowing about stationery is, quite simply, it’s a passion of mine. While some may find something akin to passion in their marriage or by binge watching Heated Rivalry, I’m much more likely to get butterflies ripping the cellophane off a new notebook versus ripping – you get the picture. This is all to say that, when I tell you Plotter makes some of the most beautiful notebook covers out there, you need to believe me. And when I tell you that pricetag flirting somewhe...

Introducing – The Vulcain Skindiver Nautique Meteorite, a New Dial for a Compact Diver

Since its debut in 2023, Vulcain’s Skindiver Nautique has quickly moved from a niche revival piece to a regular part of the brand’s present-day catalogue. These watches draw inspiration from Vulcain’s 1960s skin-diving models. Back then, diving as a hobby was gaining popularity, and compact, practical dive watches like the Nautique felt at home both in and […]

Glashütte Original released its Serenade Luna in 2024, featuring moon phase indications. Unlike the Panomatic Luna, which is essentially a scaled-down adaptation of the men’s PanomaticLunar with its off-centred dial and Panorama date window, the Serenade Luna was conceived from the start as a women’s watch with a petite 32.5mm diameter, a sprinkling of diamonds and […]

Hands-On: Audemars Piguet Royal Oak “Jumbo” Extra-Thin Openworked SJX Watches
Audemars Piguet Royal Oak “Jumbo” Extra-Thin Mar 9, 2026

Hands-On: Audemars Piguet Royal Oak “Jumbo” Extra-Thin Openworked

The Audemars Piguet (AP) Royal Oak “Jumbo” Extra-Thin Openworked 39 mm is an appealing new variant of a watch that’s already in short supply, famous as much for its scarcity as its octagonal bezel. Seen previously in white gold, the Jumbo Openworked returns at the top of its class with a case made from lightweight titanium and palladium bulk metallic glass (BMG), a material that gives the bezel its almost ethereal mirror finish. The Jumbo Openworked is not a limited edition, but its undeniable appeal will make it hard to come by, even by Royal Oak standards. Ideal configuration The Royal Oak is one of the most sought-after watches in the industry, and one of the few collections that consistently trades at a premium to retail, according to WatchCharts. With its iconic Genta design, slim form factor, and high-end calibre, it’s easy to see why. That said, some configurations are more appealing than others, and this titanium and palladium version of the Jumbo Openworked ranks highly in the Royal Oak pantheon. It’s worth exploring why it works. Starting with the sizing. In 1972, the Royal Oak was broad and flat by industry standards, but the “Jumbo” moniker now feels misleading for a 39 mm watch. Ironically, the “Extra-Thin” designation also feels misleading for the opposite reason - 8.1 mm is plenty thin, but there are now so many thinner watches that the terminology feels out of date. Setting aside AP’s historical naming conventions, the Jumbo Openworked...
