Corum celebrates its 60th anniversary this year with a distinctive flying tourbillion timepiece with a special construction that looks like it came from the archives of Harry Houdini. The Admiral’s Cup Legend 42 Flying Tourbillon features Corum’s trademark nautical-themed case design – more about that in a minute. But the thing that grabs your eye […]

Hands-On: the Beaucroft Arc Worn & Wound
Beaucroft Jul 10, 2026

Hands-On: the Beaucroft Arc

There’s genuine horological history in the home of Beaucroft Watches, the independent brand founded in 2020 in Cambridge. England was once the heart of the world’s finest watchmaking, a legacy that dated back to the 16th century. Some of the most important innovations originated in these early epochs, up until Switzerland took the mantle in the mid-1800s: complex clocks meant for royalty, and instruments for gauging the stars and the sea alike. Thomas Tompion, the “Father of English Clockmaking,” pioneered the hairspring as a viable means of regulating time, clockmaker Thomas Mudge invented the lever escapement in 1755, and John Harrison’s marine chronometer solved the problem of determining longitude once and for all.  Zoom forward about five centuries. Some of the most exciting, historically-minded efforts in independent watches are emerging from British watchmakers, many of whom are attempting to evoke this proud tradition. For Beaucroft, whose latest watch is the Arc, there’s no lack of influence to draw from among Cambridge’s stone archways, pointed Gothic windows, and the ancient towers that loom over King’s and Trinity Colleges.  The Arc is an evolution of Beaucroft’s last release, 2023’s Seeker, which laid the groundwork for the watchmaker’s design language. Namely, pill-shaped baton markers with unique markers at 3, 6, 9, and 12 that feature round pips at the end, resembling automotive gauges. Diamond-cut hour and minute hands are shaped li...

Farer Introduces a Trio of Classic Racing Inspired Chronographs Worn & Wound

Farer Introduces a Trio of Classic Racing Inspired Chronographs

Nothing beats the bold and brash hand-painted liveries of motorsports in the 1960s and 1970s, especially compared to the overstimulating and overcorporatized wraps of today’s racecars. No, liveries of old were meant to invoke speed and evoke a sense of romance and adventure—and yes, also to occasionally advertise a sponsor.  In celebration of those iconic liveries of the golden years of motorsport, British watchmaker Farer has unveiled a new trilogy of colorful chronographs. Each of the new models takes on a colorway seen on racetracks of yesteryear, while maintaining the motorsport-inspired design of their chronograph lineup. The new Racing Chronographs measure in at a slim 38.5mm in diameter and 13.4mm in thickness, making the stainless steel case comfortable on the wrist for long sessions behind the wheel. Each model features three subdials at 3, 6, and 9 o’clock, with hours, minutes, small seconds, and 30-minute and 12-hour counters. A bidirectional bezel with a ceramic insert wears a 12-hour scale and along with the hands and indexes, is filled with Super-LumiNova for legibility and visibility.  Inside, and visible through a flat sapphire crystal exhibition caseback, is a Sellita SW510M b Elaboré grade movement. Decorations include skeleton framework, perlage finishing, blued screws, and a custom engraved bridge with the Farer monogram just below center. A 63-hour power reserve ensures that setting the watch down between race days won’t be an issue. I’ve ...

Introducing: Serica Downsizes Its Field Chronometer With The 35mm Ref. 7505 Hodinkee
Serica Downsizes May 21, 2026

Introducing: Serica Downsizes Its Field Chronometer With The 35mm Ref. 7505

What We Know It's time to put aside the debate of big watches versus small watches. I think we can at least agree that options are a good thing, so everyone can get what they want. With that in mind, Serica has released three new, smaller Field Chronometer watches measuring only 35mm by 9.6mm thick with a COSC-certified automatic movement and three new enamel dials. These three new watches, with stainless steel cases, play off the design language of the ref. 6190 with a few tweaks. There's the slightly larger, fixed bezel with pips at 3, 6, 9, and 12 o'clock. They have a double-domed anti-reflective sapphire that should somewhat magnify the smaller dial. The two-tone cream-and-black "Tuxedo" dial is similar to the ref. 6190 TXD, with hand-applied numerals. The other two, the "Minute Critical" dials in black or olive green, aren't that far from the ref. 6190 "Denali" that is already on offer in a larger size, with added 5-minute Arabic numerals. All three have Super-LumiNova C3 lume. Inside the case is the SoProd M100 movement, which is COSC-certified for accuracy, making it a Field Chronometer in both name and function. The caliber runs at 4Hz, is self-winding, and has a 42-hour power reserve. According to Serica, it also has a decorated plate with Côtes de Genève, and while there are no photos of the caseback, I would assume it is still a closed caseback like its big sibling.  Then there's the final major update: the watch comes with a redesigned Bonklip bracelet, fea...

Up Close: Rexhep Rexhepi Chronograph Flyback RRCHF SJX Watches

Up Close: Rexhep Rexhepi Chronograph Flyback RRCHF

Akrivia founder Rexhep Rexhepi’s latest creation is the first complication solely under his own name, the Rexhep Rexhepi Chronograph Flyback (RRCHF). Very much embodying his defining style both in terms of aesthetics and execution, the RRCHF nonetheless illustrates the evolution of his approach to watchmaking, particularly in the subtle, fine details of the movement. With a three-register layout that brings to mind historical pocket watches, the RRCHF has a fired enamel with a modern twist in the form of sapphire counters. The movement, on the other hand, reflects Mr Rexhepi’s love of symmetry and fine decoration, while also incorporating a useful bonus in the form of an instantaneously jumping minute register. Initial thoughts After having enjoyed unparalleled success with his time-only creations – exceptionally elaborate but still three hands – Mr Rexhepi is executing a plan he has long talked about: realising his interpretation of the important complications in watchmaking. The RRCCHF is perhaps only the start of the plan, but it is a magnificent chronograph. Conceptually, it is similar to one of the great chronographs, the Lange Datograph, but sans date. While the Datograph, way back in 1999, sought to essentially replicate the intricacy of a pocket watch movement with elaborate exaggeration, the RRCHF is clearly a modern creation, yet imbued with numerous traditional and historical elements. The overall style is now familiar; it echoes the design of the Chrono...

TAG Heuer Introduces a Monaco Inspired by F1 Races Held Under the Lights Worn & Wound
TAG Heuer Introduces Nov 20, 2025

TAG Heuer Introduces a Monaco Inspired by F1 Races Held Under the Lights

For the second time this week, TAG Heuer has introduced a rather audacious Monaco. Yesterday we told you about the all new Air 1, a flagship of sorts that puts all of TAG’s resources to bear on a split second chronograph with no compromises. Today, TAG debuts a Monaco that’s a bit more accessible but no less specialized, a watch that is meant for F1 fans celebrating the unique experience of the circuit’s night races. Even a casual F1 observer (I count myself in this category) can appreciate the spectacle of a night race. It’s a very different aesthetic experience than a race run during daylight hours, and the new limited edition Monaco seen here really leans into that night race vibe with some dramatic applications of color throughout. To start, it’s built on a 39mm titanium case that has been DLC coated, and given a skeletonized dial treatment that we’ve seen from a bunch of earlier Monaco limited editions at this point. Where this watch really sets itself apart though a gradient effect that is layered throughout the dial and unique lume application.  Multiple lume colors are employed to draw the eye to either the chronograph or time telling functions, depending use case. The chronograph totalizers at 3 and 9 are rendered in blue, with turquoise hands, while green glowing lume is found on the primary hour and minute hands. There’s also additional purple lume throughout the minute track, and the bridges themselves have been given a gradient effect that range...

Urwerk’s UR-10 Spacemeter is Sci-Fi and Almost Conventional SJX Watches
Urwerk s UR-10 Spacemeter Oct 15, 2025

Urwerk’s UR-10 Spacemeter is Sci-Fi and Almost Conventional

Known for its avant-garde approach to watchmaking, Urwerk takes a surprise detour into orthodoxy with the UR-10 Spacemeter. At least at first glance, it is a round(-ish) sports watch with an integrated bracelet – and normal hour and minutes hands – as well as indicators you’ll find on no other watch. But conceptually, the UR-10 Spacemeter is typical Urwerk. The indicators on the dial are all astronomy related, bringing to mind past Urwerk models and the brand’s sci-fi style. Initial Thoughts Oddly, I find I find myself more impressed with the UR-10 aesthetically than technically. Urwerk has cultivated a military, sci-fi aesthetic that I’ve become enamoured with, especially the EMC. And, if the UR-10 is anything like its similarly sized and braceleted peers, it will wear well too. Then there are the dials, with ideal typography, which sit under a sapphire bubble and remind me of a flush-mounted ship’s compass. The complications are inspired by an unusual 19th-century regulator clock by Gustave Sandoz, and attempt to track both the Earth’s rotation and revolution. An interesting idea, but the execution is disappointing as the indications aren’t particularly mathematically accurate and based on arbitrary distances, like 10 km, rather than natural phenomenon like, say, a sidereal time watch, where one rotation of a sidereal hour hand corresponds to one rotation of the Earth. However, Urwerk likes to develop ideas over time, and the Spacemeter concept has potent...

Louis Vuitton’s Jacquemart Pocket Watches Journey Around the World

Translating as “Stopovers Around the World”, Escale Autour du Monde is Louis Vuitton’s collection of unique and lavish minute repeating pocket watches. The collection now counts two watches: Escale en Amazonie that depicts the heart of the rainforest, while the just-launched Escale Au Pont-Neuf is set just outside Louis Vuttion’s headquarters in Paris. Each timepiece is unique and powered by a new, purpose-built repeating movement with automata, also known as jacquemart, tourbillon, and an eight-day power reserve. Aside from watchmaking complications, the pocket watches also boast elaborate decoration, namely enamel and hand engraving, encapsulating the many crafts and skills possessed by La Fabrique du Temps (LFT), the Louis Vuitton manufacture in Geneva. The LFT AU14.03 Notably, the Escale Autour du Monde is actually Louis Vuitton’s second haute horlogerie pocket watch offering. The collection follows last year’s Asnières-themed pocket watch that was actually powered by a wristwatch repeater movement. The pocket watches of Escale Autour du Monde retain the same 50 mm diameter as the Asnières but with the LFT AU14.03 calibre within was developed from the ground up as a pocket watch movement. Escale en Amazonie (left), and Escale Au Pont-Neuf Initial thoughts Usually, modern pocket watches either rely on wristwatch movements (like the Escale à Asnières from last year) or near-century-old ebauches completed in the modern day. Louis Vuitton didn’t take th...

Alpina Re-Issues a Classic with the Heritage Tropic-Proof Handwinding Worn & Wound
Alpina Re-Issues Apr 1, 2025

Alpina Re-Issues a Classic with the Heritage Tropic-Proof Handwinding

The original Alpina Tropic-Proof, released in 1965 under mysterious origins-even the Swis brand itself can’t pinpoint the exact date-was emblematic of the newfound adventurous spirit ushered in by the now-accessible boom of transatlantic air travel. With a case designed by François Borgel and a handwinding movement, the Tropic-Proof was meant to be a watch-of-all-trades that could travel the globe with ease, rather than a specialized tool. Six decades later, Alpina is reissuing that design with key nods to the model’s history and future. Appropriately dubbed the Heritage Tropic-Proof Handwinding, the watch is enveloped in an understated stainless steel case that measures 34mm in diameter. Both dial options-shiny-finished white or black-contrast well with the applied silver indexes and polished silver hands, and the dial design excels in its simplicity, without conceding elegance. The hour and minute hands, as well as the dotted minute track, are coated in beige Luminova to give the Tropic-Proof ease of use in darkness. A beige Alcantara strap with a pin buckle adds a touch of sophistication, but not overzealousness, keeping the watch within the boundaries of subtle class. A threaded solid caseback with an engraved Heritage pattern hides the handwinding AL-480 caliber movement, which touts a 42-hour power reserve. Capping off the simple but elegant design is an anti-reflective glass box sapphire crystal, which curves downwards to maintain viewing ease at all an...

Everything You Need to Know About Sinn’s Latest Dive Watch Collection

There are several places you’d never find me-gas station bathrooms, water parks, and tiny airplanes come to mind-but perhaps the very last place I’d ever agree to set foot would be inside a submarine. Stuck inside a metal tube with the crushing weight of the ocean all around you? No thanks, I’ll stay on land. Still, it’s hard to deny the romance of the submarine, especially given that our ocean is still largely unexplored. Whether in scientific expeditions or military endeavours, the remarkable underwater vessel has long gripped the human imagination.  With their latest U series of divers, Sinn is honoring a piece of that maritime history. In part a celebration of 20 years of the German brand using submarine steel in its diving watches, the U15, U16, and U15 each represent a different 1970s German submarine of matching name. The name isn’t just a superficial connection, though-each model of these new U series is limited to 1,000 pieces, and features a case and bezel constructed with submarine steel from the outer hull of the actual corresponding namesake submarine.  What Sets the Models Apart?  At first glance, each U diver looks very similar-they all share that satinized submarine steel case, a captive dive bezel with minute ratcheting, a screw-down crown at the 4 o’clock position, and a striking dark blue-green high-gloss dial with a stream of lighter blue bubbles down the center. But as the names suggest, each yields slightly different design elem...

TAG Heuer Unveils their Latest Edition of the Chronosprint, an Unusual Chronograph Celebrating Porsche

TAG Heuer has re-teamed with Porsche for a follow up to one of their most popular collaborations of the last few years. The new TAG Heuer Carrera Chronosprint x Porsche Rallye builds on the success of 2023’s TAG Heuer Carrera Chronosprint x Porsche, evolving the watch with a new dial and a few other changes to celebrate the 60th anniversary of the Porsche 911’s early success at the 1965 Monte Carlo Rally. The big selling point of the Chronosprint, which is based on the visual format established by the ‘Glassbox’ Carrera introduced in 2023, is the unique implementation of its chronograph. Where a traditional chronograph’s sweep seconds hand will move around the dial at an even pace, the Chronosprint’s chronograph hand jumps off the starting line, sweeping across a third of the dial in 9(.1) seconds, before slowing down over the next 49.9 seconds to cross the minute mark at, well, a minute, before speeding up again. It’s one of the rare watches I’ve encountered in recent memory that feels like it offers a genuinely unique take on what is otherwise a pretty standard complication. For the most part, this year’s Chronosprint is the same watch Zach introduced 18 months ago, save for a handful of aesthetic changes, inspired by the Porsche 911 “147” used for the 1965 Monte Carlo Rally. Foremost among these is that this year’s Chronosprint drops the silvered dial of the last model in favor of what TAG Heuer is calling a “Black Shimmery” dial. Basically, ...

[Video] Review: the Zenith Defy Extreme Diver Worn & Wound
Zenith Defy Extreme Diver When Aug 14, 2024

[Video] Review: the Zenith Defy Extreme Diver

When I write reviews, I find myself bucketing watches into two distinct categories. The first of these is home to watches that feel like they’re meant for a different version of me, if not a different collector altogether. These are the watches that, whether I love them or not, I’d be hard-pressed to really see as part of my day-to-day life - at least as my life exists now. The other bucket is where watches like the Zenith Defy Extreme Diver live. This is the bucket for the watches that seem to hit right in my wheelhouse - the watches that seem like they were purpose-built to appeal to me (and possibly to my wallet). The minute I saw the press release for the Defy Extreme Diver, I knew it sat in this second bucket, and I knew I needed to spend some time with it, if not for a review, then certainly to consider whether this watch was one I needed in my life. Fortunately, I didn’t have to wait all too long, and after a couple of weeks with the Defy Extreme Diver on my wrist I can easily confirm what at first I only suspected - it is very, very good. There’s an inherent irony that comes along with the very concept of a luxury tool watch. The tension between building a rugged tool watch ready to tackle the world’s most demanding environments and building a high-end luxury product is palpable. To make a watch that straddles those two worlds without looking too much like a Submariner is even harder.  With the Defy Extreme Diver, Zenith has managed to make somethi...

Norqain Debuts the Latest in their Neverest Collection

Mt. Everest has long held a grip on our cultural consciousness – and for good reason. Not only is it Earth’s highest mountain, but it takes an almost superhuman amount of determination and grit to scale it. Then, of course, there is the rich history of the Himalayas, making for an even more fascinating landscape – geographically and culturally – for our imaginations to explore. With all of this in mind, it seems that NORQAIN’s latest in their Neverest collection shows appreciation to the history, mystique, and people of the region through their Glacier Black and Ice Blue references. The 41mm DLC coated Neverest GMT Glacier Black features a black glacier dial inspired by the crevasses on Mt. Everest, with a second time zone and a 24-hour indication on a black and white ring surrounding the dial. The DLC black coating brings the overall appearance of the watch together, while the red-gold plated indices and hands add some contrast. The 40mm Neverest Glacier Ice Blue boasts an ice blue glacier dial with cracks that mimic the crevasses on Mt. Everest. The dial features diamond-cut, faceted blue indexes filled with white Super-LumiNova and blue diamond-cut faceted hour and minute hands. The steel case is paired with a blue ceramic bezel and is water-resistant up to 200 meters, ensuring reliability under even the most extreme conditions. Both watches are powered by a NORQAIN Manufacture Caliber by Kenissi. The Glacier Black model runs on Caliber NN20/2, which offers a ...

IWC’s Mark Series Turns 75, and the Brand Celebrates with a New Silver Dialed Variant of the Popular Pilot’s Watch

Last year, IWC launched the Mark XX in a somewhat unusual way for a marquee watch from a big Swiss brand: without much fanfare at all. We’re accustomed in the watch world to getting teased about new releases weeks ahead of time, with splashy PR campaigns to accompany the biggest reveals. The Mark watches, for many watch enthusiasts, are the watch collection that comes to mind when thinking about IWC. So for the new Mark, arguably the most critical of the entire Pilot lineup (don’t @ me, Big Pilot fans) to just kind of appear on the website one day last year was a little surprising.  Now, almost a year later, the Mark XX is very much out there and certainly no longer an under the radar secret to stumble over. The subtle updates to the dial (including a date window which appears to be a bit more in harmony with the outer Arabic numerals clocking the hours) and a higher spec movement have gone over well with the collector community, and the Mark XX is the rare update to a core collection watch, from any brand, that seems to have a consensus around being an improvement. Think about how rare that is, for a minute. When the new 41mm Submariner was announced in 2020, Rolex fans were close to war. But with the new Mark, if you liked the last one, chances are you were going to like this one more. If it was never your thing to begin with, your opinion probably didn’t change. It was that most uncommon type of watch release: one with no real controversy.  Since the black and b...

Cartier Introduces the Privé Tank Normale SJX Watches

Cartier Introduces the Privé Tank Normale

Cartier has long mined its extensive archives for inspiration, particularly for the Privé collection of historically-inspired watches. Having revived the Tank Asymetrique and Cloche, the jeweller now turns to the first-ever Tank with the Privé Tank Normale. Like past Privé models, the new Normale faithfully adheres to the historical original, but unlike other Privé models, it is offered with the option of a matching, precious-metal bracelet. Initial thoughts  Like last year’s Privé Tank Chinoise, the Tank Normale is less familiar than say, the Tank Cintree, having been discontinued for some time. Although the Tank Normale was the original Tank design of 1917, it has been out of the catalogue for long enough to have some novelty. The Tank Normale stays true to the original in almost all respects. The case, for instance, is marginally larger than vintage examples but compact enough it feels like a vintage watch. Even the bevelled sapphire crystal mimics the glass on the originals. But the watch incorporates modest tweaks that set it apart as a modern watch, like the expanded railway minute track. These design updates reveal a good attention to detail in updating the watch without changing too much. Especially noteworthy is the bracelet, an option rarely offered by Cartier for its high-end men’s watches. It’s executed well in both design and build, while also being acceptably priced as such things go (although pricey in absolute terms). The OG Tank The Tank Norma...

De Bethune Introduces the DB Eight SJX Watches

De Bethune Introduces the DB Eight

While De Bethune is best known for its avant-garde designs and signature spring-loaded floating lugs, the brand’s early years were characterised by more traditional styling. Fresh off the press, the DB Eight calls to mind the brand’s early products, most notably the DB1 mono-pusher chronograph from 2002, but adds many of the technical refinements that De Bethune has become known for.  Dressed in a polished titanium case and guilloché dial, the DB Eight fills a hole in the brand’s current line-up by offering collectors a simple, manually wound mono-pusher chronograph, albeit one that lacks the technical and decorative refinement collectors expect at this price point. Thanks to its wide but slim case and narrow bezel, the DB Eight will likely wear larger than its 42.4 mm diameter would suggest Initial thoughts I’m probably in the minority when it comes to my preference for De Bethune’s more classically styled models like the original DB1. Given this preference, I naturally I gravitated towards the new DB Eight more than I have to some of the brand’s other recent offerings like the DB28XP. But while I like the design of the DB Eight, the substance does not meet my expectations for the brand. Let’s start with the good news. De Bethune has addressed the cross-eyed look of the DB1 with a new movement that offers an instantaneous 60-minute counter for the elapsed time at six o’clock. This creates a balanced look that at first glance might even pass for a time-...

Stories: A Legendary Iranian Pilot and His Rolex GMT-Master

Gunshots ring out with an unnerving cadence, and the chants of angry crowds ring across the city. It is Sunday, February 11, 1979. Come Monday morning, the country’s biggest newspaper hits newsstands with the front page proclaiming: “The Regime Has Disintegrated”. The provisional government collapsed the day before, with the military having returned to its barracks – leaving the Islamic Revolution triumphant. All day long that Monday, a young man ignores the revolutionary chaos as best he can, dedicating himself to picking up the phone every hour and dialling his father’s office at air force headquarters within Doshan Tappeh Air Base in Tehran. Each time his father answers and calmly reassures the son all is well. For a few months now, the son has tried to talk his father into leaving the country. The Shah had already fled and tensions were rising. But each time his old man responded in the same manner, “I am a soldier of this land and my duty calls me to stay.” Not only did the father remain in the country, he dutifully turned up to work every day. Nader Jahanbani (right) with Mohammad Reza Pahlavi, the last Shah of Iran, in the early 1970s; Nader has his GMT-Master on his wrist On that fateful Monday, the son calls at six in the evening and hears his father’s voice.

In-Depth: A History of the Pulsations Chronograph SJX Watches

In-Depth: A History of the Pulsations Chronograph

In 1816, Louis Moinet accomplished a first in watchmaking: a timepiece that could precisely track elapsed time. Measuring periodicity on demand had been accomplished before, but the French watchmaker’s invention gave it the functionality and exactness that we expect today. In assessing prototypes, we often tend to forgive their shortcomings and rosily reminisce, rewriting flaws as charms. Moinet’s timepiece, however, was a prescient opus. The layout of the dial had the now-familiar large central hand and elapsed time in subdials. Two pushers controlled the start, stop and reset functions, the power reserve lasted over 30 hours, and the mainspring could be wound while the timing mechanism was engaged to allow for longer timing runs. Most impressive, though, was its precision. Louis Moinet’s compteur de tierces of 1816. Image – Louis Moinet Named the compteur de tierces, or “timer of thirds”, Moinet’s invention ran at 216,000 beats per hour, measuring time down to one-sixtieth of a second. To allow for this ambitious exactitude to be utilised, the central chronograph hand completed revolutions once per second – such that the user could easily see which sixtieth of a second the period in question ended on - and the watch had an extra sub-dial for tracking elapsed seconds in addition to those for the minutes and hours. Whys and wherefores An impressive story, except that it’s missing something. Why did Moinet build it? And what did he use it to measure? A...
