Patek Philippe 5002 Sky Moon Tourbillon: The Most Complicated Wristwatch Produced by Patek Philippe

The Patek Philippe 5002 Sky Moon Tourbillon launched in platinum for the 2001 model year, the 12-complication featured two dials. Dial one was devoted to a moonphase indicator and a perpetual calendar with retrograde date display. On the sub-dial display for months, simple text promised a tourbillon regulator within the case.

Understanding the Vacheron Constantin Solaria with Christian Selmoni and Jean-Marie Bouquin SJX Watches
Vacheron Constantin Solaria Jun 9, 2025

Understanding the Vacheron Constantin Solaria with Christian Selmoni and Jean-Marie Bouquin

SJX recently visited Vacheron Constantin  and sat down with Christian Selmoni, style and heritage director, and head of speciality watchmaking, Jean-Marie Bouquin, to discuss the Les Cabinotiers Solaria Ultra Grand Complication, the most complicated wristwatch yet made. Mr Bouquin led the development of Solaria, and assembled it, creating a wristwatch that’s a worthy follow-up to the most complicated portable timepiece ever, the Berkley Grand Complication that was launched just last year. That in turn broke the record set by Vacheron Constantin in 2015 with the ref. 57260 “Tivoli”. They discussed the intricacies and innovation in the Solaria, including its modular “plug and play” perpetual calendar, and the implications for future Les Cabinotiers projects, as well as the novel star-tracking chronograph, and the benefits of using silicon for the spokes of the balance wheel. They also touched on the absence of a grande et petite sonnerie.

Introducing – The Frederique Constant Classic Tourbillon Manufacture, now with Light Blue MoP Dial

The tourbillon has long been one of the long list of complications developed internally by Frederique Constant, used as a stand-alone feature or even paired with a perpetual calendar. And, in classic style for the brand, often with a price that’s well below the industry average. A couple of years ago, in line with its […]

IWC Debuts the Long Awaited Pilot’s Watch Automatic 41 Top Gun Mojave Desert Worn & Wound

IWC Debuts the Long Awaited Pilot’s Watch Automatic 41 Top Gun Mojave Desert

IWC’s releases this year are proving something that I’ve always felt was true, but lacked hard evidence: if you’re patient, the watch you’ve always wanted will one day appear. Perseverance takes many forms, and there’s no doubt that one of them is telling your IWC sales rep that you’ll actually pass on the Mojave Big Pilot, Perpetual Calendar, and Pilot’s Chronograph, and wait for the simple three hander in a casual, everyday size. Today, IWC announced a watch many in the Worn & Wound office have been attempting to conjure since the very first Mojave watch appeared back in 2019, a limited edition Pilot’s Watch Chronograph measuring in at 44.5mm. The aforementioned perpetual calendar and Big Pilot in the Mojave colorway followed, as did another chronograph in a smaller, 41mm size. But this is the one many enthusiasts, I think, have been waiting for, and it follows a larger trend of predictable (and desirable) iteration within the larger IWC family.  What we have here is relatively simple on its face: the Pilot’s Watch Automatic 41 Top Gun Mojave Desert takes the tan ceramic IWC has been using in the Top Gun line over the last six years and puts in the most straightforward IWC pilot watch concept of them all. While it’s not technically a Mark series watch (IWC draws a distinction between the Mark line and their more experimental, ceramic dominated Top Gun pilot’s watches) the form factor and principle here are both similar. The 41mm case measures a com...

Naoya Hida & Co. Has Announced their 2025 Releases Worn & Wound

Naoya Hida & Co. Has Announced their 2025 Releases

Seeing a watch made by Naoya Hida & Co. in person for the first time was one of those moments when you truly realize that you have to experience a watch in the metal before casting judgement. At the time, the brand was only in its second full year, and most of the people commenting on the watches in online forums, Instagram, etc. were reacting to what they perceived as an exorbitant price tag. These specific watches, after all, used a (highly) modified Valjoux 7750 as the base movement – not exactly high horology. But when you handle one of these watches, wear it, and, importantly, turn the crown, you realize you’re dealing with an object that’s largely handmade, a fully fleshed out complete thought with a singular perspective. That’s a pretty rare thing, as are the hand carved dials that have become an aesthetic signature of the brand, and truly require magnification to fully grapple with. Naoya Hida & Co. has just unveiled their new slate of watches for 2025, and I imagine we’re heading for some of the same conversations we’ve heard before, but there’s a new watch in this crop of releases that should quiet at least some of the naysayers.  The marquee release in this year’s lineup is the NH Type 6A, Naoya Hida’s most complicated watch to date and their first perpetual calendar. The 6A is made in the same vintage inspired style as all of Naoya Hida’s other watches, evoking classic pieces by Patek Philippe and others (but mostly Patek, let’s be honest...

Vacheron Constantin’s First Chiming Sports Watch, the Overseas Grand Complication SJX Watches

Vacheron Constantin’s First Chiming Sports Watch, the Overseas Grand Complication

Vacheron Constantin (VC) continues its 270th anniversary festivities with its first minute-repeating sports watch, the Overseas Grand Complication Openface. In addition to the repeater, the manually wound movement also features a perpetual calendar, tourbillon, and rear-facing power reserve indicator. All of this is housed in a titanium case rated to 30 m, which is a notable degree of water resistance for a chiming watch. This is also the first Overseas model with the “Openface” treatment, which pays homage to rock crystal dials found in vintage clocks and pocket watches with a clear sapphire dial exposing the perpetual calendar works. Image – Vacheron Constantin Initial Thoughts It’s unusual, but a chiming sports watch makes sense considering the direction of consumer preferences for complications. That said, the minute repeater has been slow to make its way into sports watches, despite enjoying renewed popularity for the past few decades, due to the challenges of waterproofing the charging slide and preserving sound quality. This has created a perception of water resistance and sound being mutually exclusive, which has only recently been challenged. Audemars Piguet was an early pioneer with water-resistant repeaters, and now Vacheron Constantin has entered the fray with a water-resistant minute-repeating integrated-bracelet sports watch of its own. While 30 m of water resistance is low compared to other models in the Overseas collection, it’s significant for a ...

A Minute Repeater You Can Take for a Swim: Vacheron Constantin Launches the Overseas Grand Complication Openface

Another day, another cool Vacheron Constantin release. Barely a month on from Watches & Wonders (where I will remind you, Vacheron dropped the most complicated wristwatch ever made), the iconic brand, currently celebrating its 270th anniversary, has released another high complication heater - a skeleton dial, perpetual calendar, minute repeater with tourbillon dressed up as a titanium Overseas. Coming into 2025, it was pretty clear to see that Vacheron was ready to make some noise. For one thing, the brand was (as I mentioned) celebrating its 270th birthday, something the marketing folks at Vacheron have not been shy about, but more than that, the brand has been on a pretty incredible run over the last few years. Even without the cover of an anniversary year, recent new releases from Vacheron Constantin have increasingly been greeted as objects of interest, both in a technical and cultural sense, and there’s a real feeling that someone at Vacheron HQ clearly knows what they’re doing. The new Overseas Grand Complication Openface is an objectively impressive offering. Measuring in at 44.5mm across and 13.1mm thick in grade 5 titanium (a material also seen in last year’s Overseas tourbillon) this latest Overseas does feature slightly reworked case proportions, with a narrower bracelet relative to its smaller siblings and what looks to me to be a slightly longer lug to lug and thinner bezel, relative to its admittedly larger case size. The watch is also water resistant...

Highlights: A Noteworthy Trio from Patek Philippe at Phillips Geneva SJX Watches

Highlights: A Noteworthy Trio from Patek Philippe at Phillips Geneva

It’s hard to stand out among the 194-lots in Phillips’ incredibly stacked upcoming Geneva auction. The catalog for The Geneva Watch Auction: XXI includes 36 watches from Patek Philippe, including familiar favorites like two ref. 5004s and an assortment of Nautilus and Aquanaut models. But three watches are especially notable. These highlights are led by the only known ref. 3448 “Padellone” perpetual calendar in pink gold – a retailer-signed example at that – followed by a landmark “grand” complication with Hagmann case, and a Beyer-signed pocket watch with a portal to Amsterdam on the back. The auction takes place on May 10 and 11, 2025, at the Hotel President Wilson in Geneva. Lot 74: Patek Philippe ref. 3448 in pink gold signed “Freccero” Patek Philippe’s first self-winding perpetual calendar, the ref. 3448, was primarily made in yellow or white gold – except for this example in pink gold. Besides the unique case material, this also has a retailer-signed dial. In addition, it’s in incredible condition, with unpolished lugs so sharp you could almost cut yourself. It features an early “second series” dial, with a “dimple” style minute track and engraved, enamelled markings. Even though the movement inside the ref. 3448 is one of the most beautiful automatics ever made, the cal. 27-460 doesn’t skate by on pretty privilege. The calibre is technically competent: with a free-sprung gyro-max balance, overcoil hairspring, and Patek Philippe’...

Vacheron Constantin Introduces the Most Complicated Wristwatch, Ever Worn & Wound

Vacheron Constantin Introduces the Most Complicated Wristwatch, Ever

If you were to sit me down at a desk and ask me to write down 41 watch complications off the top of my head, I think the result would be rather like Ross Geller trying to name the 50 states in that one episode of Friends. There’s just no way I could do it. Forty-one is an absurd number of complications to even conceive of, let alone cram into one surprisingly wearable watch. And yet, that is what Vacheron Constantin’s one-of-a-kind watchmaking department, Les Cabinotiers, has managed to do. Just about a year after introducing the world’s most complicated watch of any kind - a pocket watch containing 63 complications - Vacheron has unveiled the Les Cabinotiers ‘Solaria Ultra Grand Complication.’ It’s hard to know where to start with a watch like this, especially since I haven’t had the opportunity to see it in person, so to begin, I’ll just say this: I am wildly impressed by this watch, and you should be too. It’s a serious step up from their previous most complicated wristwatch - the Vacheron Constantin Les Cabinotiers Celestia Astronomical Grand Complication 3600, which housed 23 complications. It’s worth saying here that, even before getting to the Solaria Ultra Grand Complication, Vacheron Constantin had a very good Watches & Wonders. The brand is celebrating its 270th anniversary this year and they’ve done a hell of a job with it. Their new 127-piece limited edition Traditionelle Tourbillon Perpetual Calendar, with its novel movement and ann...

Bremont Debuts their Revamped Pilot Watches in the Altitude Line Worn & Wound
Bremont Debuts their Revamped Pilot Apr 2, 2025

Bremont Debuts their Revamped Pilot Watches in the Altitude Line

Last year was, no matter how you look at it, a transformational one for Bremont. Nowhere was this more obvious than at Watches & Wonders 2024, where the English brand rolled into Palexpo with a new CEO, new watches, and an entirely new brand identity. To say they caused a stir would be an understatement, and the brand’s radical reinvention was one of the prevailing narratives in the show’s aftermath. Still, amidst all the discourse and new collections, one key Bremont tentpole went undisturbed last year - but no longer. Now, for Watches & Wonders 2025, Bremont is introducing an updated offering of pilot’s watches, bringing what is arguably Bremont’s most important collection of watches in line with the rest of the new Bremont catalog. The updated Altitude lineup is made up of three new models: The Altitude 39 Date, the Altitude Chronograph GMT, and the Altitude MB Meteor (a successor to the MBII), and offers the best balance so far between a classic Bremont feel and the brand’s updated identity. There’s also a perpetual calendar to be discussed, but that’s for another time. Notably, each of the new watches retains Bremont’s hallmark Trip-Tick case, which was notably omitted from last year’s launches. Still, there is no confusing these for old-school Bremont. The updated Altitude collection boasts a slimmer look, with thinner lugs and bezels, and the watches each adopt a near-monochromatic colorway, dropping some of the colorful flourishes Bremont has of...

First Look – The New Frozen Editions of the H. Moser Streamliner Flyback Chronograph Automatic

The Streamliner collection was introduced by H. Moser & Cie in 2020 and was an overnight success. Its groovy integrated cushion design was fresh, original and brilliantly executed.

A. Lange & Söhne Plays the Classics with the Minute Repeater Perpetual

Topping A. Lange & Söhne’s 2025 line-up is the Minute Repeater Perpetual. Featuring a compact platinum case and black enamel dial, the new flagship watch of the Saxonia line marks the first time Lange has combined these two classic complications on their own. Limited to 50 pieces in platinum, the Repeater Perpetual is positioned near the top of the current catalogue. Beyond the technical complexity, it’s been endowed with an exceptional white gold and black enamel dial crafted in-house, and features the frosted movement finish that’s often reserved for the brand’s special editions. Initial thoughts It’s always nice to see a brand cover new ground, especially when that ground is the tried-and-true combination of a minute repeater and perpetual calendar. It’s an extravagant, decadent watch that combines one of the most legible perpetual calendar layouts with one of the industry’s most technically sophisticated minute repeaters. Beginning with its compact form, the Repeater Perpetual packs 640 components inside a platinum case that’s just 40.5 mm wide and 12.5 mm thick; roughly the same dimensions as a Rolex Submariner. It features an enamel dial in deep black, which is always a risk, since even the tiniest imperfections tend to stand out vividly. A cynic might point out that the new calibre L122.2 is largely a mashup of a Langematik Perpetual and Richard Lange Minute Repeater, but to do so would be to miss the point. The movement is everything Lange does be...

Seiko’s Advanced Astron Collection Gets Four New References Worn & Wound

Seiko’s Advanced Astron Collection Gets Four New References

If you like your watches complicated and your timezones varied, chances are you’re already aware of the Seiko Astron GPS Solar line, first launched in 2012. No, the watch doesn’t shout haphazard driving directions at you. Instead, its latest models use GPS technology and a solar-sensitive dial to automatically update the time according to your geographic position up to twice a day. But Seiko wasn’t done there-almost exactly a year on from the introduction of the Caliber 5X83, the first pairing of Dual-Time tech with a chronograph function, Seiko has unleashed four new Astron GPS Solar Dual-Time Chronographs. Each of the four new watches-references SSH175, SSH177, SSH179 and limited-edition SSH180-features a titanium bezel with a sapphire crystal insert, adding a touch of practicality and elegance to the already robust profile of the Astron. An imposing 44mm mirror-polished titanium case houses the Caliber 5X83 movement, which promises a litany of advanced features, most prominent of which is the aforementioned GPS-controlled time and time zone adjustment. A world time function, perpetual calendar correct to the year 2100, automatic DST adjustment, AM/PM and signal reception indications, accuracy of +/- 15 seconds per month, and more round out the slate of functions. Of course, the titular chronographs also loom large on the dial, with a 1/20th second counter at 12 o’clock and a 12-hour counter with hours and minutes at 6 o’clock during chronograph operation...

Seiko Refines Mar 17, 2025

Seiko Refines the Astron GPS Solar Dual-Time Chronograph

One of the flagship high-tech analogue watches in Seiko’s catalogue, the Astron GPS Solar Dual-Time Chronograph has been reworked to give it visual elements more typically associated with Seiko’s higher-end mechanical watches. Amongst other things, the new Astron GPS chronograph features a sapphire-covered bezel, diamond-milled chapter rings, and facetted case details. It still retains the multi-function 5X83 movement that features GPS time- and time zone setting, perpetual calendar, and a six month power reserve on a full charge. Initial thoughts Someone recently asked me to recommend a useful watch for a person who has no interest in mechanical timepieces, with the condition that the watch has to be analogue and not look like a gadget. The Astron GPS chronograph fits the bill. The model’s newest iterations, four in all, have the styling details of a mechanical watch while having a multitude of high-tech features. One of its most useful features is the GPS time setting, which means the watch syncs with a GPS satellite and then displays the local time zone when travelling. The black and blue dial versions are especially restrained and well suited as a low-key everyday watch, though still a little large at over 44 mm in diameter. Useful watchmaking When sunlight is detected, the Astron GPS chronograph syncs with a GPS satellite automatically up to twice a day, while manual syncing can be done via a pusher in the case. Sunlight also powers the watch – under the dial ...

Introducing – Unique, Striking Code 11.59 Grande Sonnerie Models for AP’s 150th Anniversary

As you probably know by now, Audemars Piguet is celebrating its 150th anniversary this year. Last week, the Le Brassus-based brand released an array of new watches, predominantly focused on a new, clever and technically advanced perpetual calendar movement getting rid of recessed correctors (it is far more complex than you might imagine…) But that […]

Audemars Piguet s 150th Feb 28, 2025

Unique Code 11.59 Grande Sonnerie Editions for Audemars Piguet’s 150th

The centrepiece of Audemars Piguet’s 150th anniversary is the ingenious perpetual calendar cal. 7138 (at least for now), but the most complicated of the commemorative editions is the Code 11.59 by Audemars Piguet Grande Sonnerie Carillon Supersonnerie. The anniversary line-up of striking watches is comprised of five unique grande sonnerie wristwatches: three have sapphire dials that reveal the intricate strikework, while the remaining pair are fitted with iridescent opal dials. The harlequin opal dial Initial thoughts Though criticised at launch, the Code 11.59 has evolved into a varied range of watches, some of which are notably appealing (some are still pretty boring unfortunately). The grande sonnerie falls into the appealing category. The mechanics of the grande sonnerie are exceptionally complicated, and because it is a Supersonnerie equipped with AP’s patented amplification construction, the grande sonnerie is incredibly loud. The volume of the chimes are loud, but not so much that they are harsh. In short, the acoustics are impressive. The sapphire dial in sand gold case The anniversary edition grande sonnerie are individually appealing, though the opal dials are more interesting due to the novelty of the material. That said, the grande sonnerie can be customised, so a buyer is not necessarily limited to the options available for the anniversary. If I wanted to spend this much on a grande sonnerie, I’d work on my own. The pinnacle of striking watches AP is one...
