In-Depth: Breguet’s Constant-Force Magnetic Escapement

Earlier this week, Breguet rounded off its grandiose 250th anniversary with the unexpected launch of the Expérimentale 1 chronometer in Paris. Showcasing modern Breguet’s most impressive innovation to date - a magnetic constant-force escapement - the watch left many scratching their heads simply because the novel invention defies easy explanation. Here we explain the actual functioning of this remarkable invention, and why it represents such a significant step forward in terms of chronometry and escapement technology. The origins of the concept Before turning to the decidedly modern and futuristic Expérimentale 1, we must first take a short trip to the past and consider how the idea of using magnets in mechanical escapements first came to life. For that we must turn to the late 1930s, when Cecil Frank Clifford, Fellow of the British Horological Institute (BHI), started experimenting with oscillators maintained by magnetic rails or escape wheels.  He was granted a British patent in 1954 for a variety of magnetised escape wheels paired with elastic vibrating magnetic blades. The device would operate silently and Clifford envisioned it being used for naval underwater torpedoes, so the lack of ticking would be harder to pick up by sonars.  Iterations of Clifford magnetic escapements. His designs were rudimentary. The principle was that the escape wheel would be braked by a vibrating pair of magnetised blades (in several possible configurations), while simultaneously ...

Baltic Adds New Prismic Stone Dials to their Permanent Collection Worn & Wound
Baltic Adds New Prismic Stone Dec 2, 2025

Baltic Adds New Prismic Stone Dials to their Permanent Collection

Baltic’s Prismic line always felt like it existed to capitalize on the stone dial trend. When the watch debuted in early 2024, the French brand’s take on the classic “cocktail watch” seemed like it was pulled from a confluence of all the forces pushing against the vintage inspired sports watch boom that preceded it. The Prismic is a small, aesthetics first, design oriented piece, about as anti tool watch as they come. Those first Prismic releases did not have stone dials, but a later set of limited editions did, and that’s when this watch really clicked into place for many of us. Now, with those LEs long gone, Baltic has introduced a new line of stone dial Prismics that will be part of the permanent collection.  The new Prismic Stone collection arrives to celebrate the opening of Baltic’s first boutique, just as the previous LEs were released to celebrate the opening of showrooms in New York, London, and Paris. The four dial options make use of stones that are not common in watchmaking: Pietersite, Pink Albite, Bloodstone, and Dumortierite. Like all stone dials, each individual piece will be unique. The standout, in my opinion, is the Pietersite dial. This is a truly dynamic stone, and looks like something that could have been ejected from an active volcano just minutes ago. Bloodstone has a dark green hue with inclusions of brown and red, and could be seen as an alternative to the more commonly used malachite. Similarly, Dumortierite has a dark blue tone that...

Breguet Ends a Big Anniversary Year with the Impressive Expérimentale 1 Worn & Wound

Breguet Ends a Big Anniversary Year with the Impressive Expérimentale 1

As if winning the top prize at the GPHG were not enough, Breguet has capped off their big 250th anniversary year with the launch of what is surely their most horologically interesting and cutting edge release in years. The Expérimentale 1 is an ambitious foray into contemporary haute horlogerie from a brand that more than most is associated with classicism. It incorporates and merges multiple technologies and advancements into a remarkably cohesive idea that might even have those of us who have always bristled at the controversial Marine collection rethinking its potential.  The showstopping feature of the new Expérimentale 1 is the tourbillon, the first ever to beat at 10 Hz. Bregust is quick to remind us that most tourbillons run at a rate of 2.5 Hz, so this represents a dramatic increase and in theory should provide a variety of chronometric benefits, including rate stability over the duration of the power reserve and a better baseline level of accuracy. But it’s not just a high frequency tourbillon. Breguet has also developed and introduced a new magnetic escapement that is designed to provide constant force to the balance. The logic here is fairly straightforward even if the mechanics themselves are, frankly, somewhat difficult wrap your arms around without real watchmaking experience (this, by the way, is essentially my constant of being as I observe similar watchmaking advancements – wide eyed and impressed but quite frequently confused by all the math and ph...

Review: A. Lange & Söhne’s Beautiful Richard Lange Jumping Seconds

The Richard Lange Jumping Seconds isn’t about showing off, it’s about showing how precise watchmaking can get. Every jump of the seconds hand tells a story of engineering perfection and timeless design. It’s the kind of watch that reminds you why A. Lange & Söhne is one of the brands that sits at the top of the horological world. What We Love Exceptional craftsmanship as always from A. Lange & Söhne. Regulator display offers a unique way of telling time. Watching the seconds hand jump precisely each second is something truly special, especially for a fully mechanical timepiece. The finishing on both the case and movement is second to none, showcasing A. Lange & Söhne’s dedication to perfection. What We Don’t The case thickness remains on the larger side; even with the added function, it could be refined further. Reading the time at a quick glance can be a little tricky due to the regulator-style layout. The watch’s refined, dressy nature means it’s not the most versatile piece for everyday or casual wear. Overall Rating: 8.8/10 Value for money: 8.5/10 Wearability: 8.5/10 Design: 9/10 Build quality: 9/10 From the moment you strap on the A. Lange & Söhne Richard Lange Jumping Seconds, you can immediately tell that this is no ordinary dress watch, but rather a refined instrument of time. Straight away you can see the level of precision, and the idea that every element of this timepiece as a role and purpose. In the world of horology, where high complications...

Breguet Reverses Polarity with the Classique 7225 SJX Watches
Breguet Reverses Polarity Oct 23, 2025

Breguet Reverses Polarity with the Classique 7225

Breguet’s 250th anniversary got off to a good start and the momentum continues with the Classique 7225, another take on one of the brand’s most inventive movements. Guaranteed to run within an impressive one second a day, the Classique 7225 contains the cal. 74SC that boasts a high-frequency balance wheel running at an uncommonly rapid 10 Hz, or 72,000 beats per hour. To achieve that without overwhelming friction, the balance pivot is magnetic, allowing it to “float” as it oscillates. The 10 Hz balance was launched some 15 years ago, but its predecessor, the Classique 7727, did not enjoy particularly attractive aesthetics. The Classique 7225 solves the problem with a striking dial modelled on an important series of tourbillon pocket watches from the early 19th century. To accommodate the dial layout, the cal. 74SC incorporates an additional constant seconds that can be instantaneously reset. Notably, the 7225 is not a limited edition, unlike its compatriot, the Classique 7235 launched at the same time. Initial thoughts The 7225 shows that Breguet’s revival is certainly well underway, stewarded by Gregory Kissling, who has been in the top job for slightly over a year. The 7225 isn’t a major revamp of the 7727, but it is far, far more appealing watch. The magnetic-pivot movement was ingenious at launch, and still is, but the 7727 was under-designed and over-logo’ed. With the 7225, Breguet’s ultra-chronometer finally has visual and tactile appeal. And it keeps...

Patek Philippe’s Gondolo Serata Zebra Debuts New Dial Technique SJX Watches

Patek Philippe’s Gondolo Serata Zebra Debuts New Dial Technique

Patek Philippe surprises with an off-season launch, the Gondolo Serata Zebra Ref. 4962/200R-010. Based on the curvaceous model launched in 2006, the Zebra features a sapphire crystal dial framed by garnets on the bezel and lugs. The dial motif replicates the cloisonné enamel dial of the Golden Ellipse ref. 5738/50G-023 from the Rare Handcrafts collection of 2022, but here the technique and material are decidedly modern. Despite the radically different look, this is an evolution of the Retrograde Perpetual Calendar ref. 6159G that has a smoked sapphire dial. Here the dial is also clear sapphire, but engraved, varnished, and then metallised to create the striking zebra motif. Initial thoughts The Gondolo Serata has been in Patek Philippe’s catalogue for almost 20 years but it never really gained prominence. Though the case shape is elegant, the dials on the earlier versions were quite plain. The Zebra is the opposite – vivid and striking – and it instantly stands out amongst Patek Philippe’s ladies offerings. The fact that the dial motif is based on the Rare Handcrafts Ellipse is a nice touch, though watch enthusiasts may be disappointed the movement is quartz. Patek Philippe presumably understands its clients and those clients probably want the convenience of a quartz movement. The sapphire dial technique, however, is interesting enough that it is likely to make its way into other models, which will be a good thing. Savannah sapphire The Gondolo Serata is a longsta...

Voutilainen Realises a Collector’s Dream, the 28 Kohan SJX Watches
Vacheron Constantin Jul 17, 2025

Voutilainen Realises a Collector’s Dream, the 28 Kohan

Voutilainen recently completed a custom commission with the 28 Kohan, a one-off example of its signature chronometer wristwatch that blends Finnish cultural symbols with Japanese decorative arts. Much of the decoration on the watch is maki-e, traditional Japanese lacquer, that is the work of artisan Tatsuo Kitamura, a frequent collaborator who was also responsible for past Voutilainen maki-e timepieces. Initial Thoughts Unique pieces and commissioned watches were historically the norm at the highest end of the watch market, which was then much smaller. Clients could be more demanding, and for the watchmaker, the risk of being unable to find a buyer was very real. Today off-the-rack watches dominate, largely for commercial and production reasons. Even brands with a long history of bespoke or custom watchmaking eschew custom dial colours. Some, however, keep the practice alive, like Vacheron Constantin with its Les Cabinotiers. Many independents also remain amenable to customisation, even established names that no longer need to, like Voutilainen, albeit with a long wait. Bespoke watches are inherently difficult to criticise – such watches are a success as long as the commissioner is satisfied, even if it’s the most hideous thing ever. Fortunately that isn’t the case here, the adjective that comes to mind is bedazzling. I suspect maximalist designs are often common on Voutilainen’s custom watches because collectors want to make the most of the opportunity. Some deta...

Bell & Ross Introduces the Stealthy New BR-03 Diver Lum Outline Worn & Wound

Bell & Ross Introduces the Stealthy New BR-03 Diver Lum Outline

Love it or hate it, Bell & Ross is committed to their iconic, oversized, and squared-off designs. But despite what their haters say, they don’t just do squares. Or rather, they layer other shapes over squares sometimes. Confused? Good. Let’s get into it.  The brand’s popular BR-03 Diver platform is home to a healthy handful of references, all of which measure in at 42mm in diameter, and feature the brand’s classic “circle within a square” design that varies in color and material between models. Basically, the iconic Bell & Ross square case remains, with a diver’s bezel laying on top, giving each model a stacked, utilitarian aesthetic. The design is effectively functional and deeply polarizing, as is B&R;’s forte.  Last year, the French brand began updating BR-03 Diver timepieces by introducing optimized changes to the movement and materials, ceramic bezels and inserts, and revised typeface, hands, and strap designs. The latest BR-03 Diver release, the Lum Outline, is perhaps the most emblematic of the line’s emphasis on functionality and capability without sacrificing stylistic panache.  The Lum Outline’s case, bezel, dial, and strap options-one rubber, and the other black synthetic fabric-are all a uniform matte black. Normally, I would say that this is tame or even boring, but the micro-blasted texture of the ceramic gives the watch a more interesting and layered look than a monochrome design usually would. The case is a solid 13.35mm thick, and...

Certina DS Action Diver 38mm Review Teddy Baldassarre

Certina DS Action Diver 38mm Review

The Certina DS Action Diver 38mm is a dive watch that has been largely off the radar of many U.S. watch enthusiasts until somewhat recently but is having a moment in our current era, in which sporty utility, striking colorways, value for money, and understated sizing reign supreme in the watch market. How much do you know about the DS Action Diver, including the meaning of “DS,” or about the not-so-famous but very historic Swiss watch brand that produced it? Read on, and you’ll be up to speed. Origins Of Certina Certina traces its roots to 1888, but it wasn’t called Certina back then. That year, a pair of Swiss brothers, Adolf and Alfred Kurth, set up a watchmaking workshop in an annex to their family home in the town of Grenchen (above), initially, to make movements and parts to sell  to other watch companies in the region. By 1906, however, they were making enough of their own complete timepieces that they introduced a brand name: Grana, which was a shortened version of the Latin word “Granatus,” referring to Grenchen. The early Grana watches found success, but for several years the Kurth brothers continued to also make and supply movements to other companies; the name “Certina” - another Latin-derived word, from “certus,” for “sure” or “certain” - began appearing on the company’s timepieces in the 1930s. The name, which was also easier to pronounce than “Grana” in more languages, was registered in 1933 and eventually became the c...

Hands On: MB&F; SP One

With its fifth new model in as many months, MB&F; has been on quite the run to kick off its third decade. Fresh off the launch of the fun and affordable M.A.D.2, which followed closely on the heels of a collaboration with Bulgari and the introduction of the the Legacy Machine Longhorn editions, the brand has returned with the SP One, a contemporary take on the open-worked dress watch. Sleeker than the typical Horological Machine yet more avant garde than a Legacy Machine, the pebble-like SP One is the first model in a new “Special Projects” collection that packages the brand’s signature contemporary aesthetic in a smaller more wearable 38 mm footprint. The SP One joins the collection as a regular production model in either platinum or 18k rose gold. Initial thoughts Picking up the SP One for the first time, one is struck by the light and airy nature of the watch. On the wrist, the minimalist case almost disappears, making the the SP One something of a wrist-worn display case for the Y-shaped movement. This effect is accentuated with a brushed internal flange dubbed ‘the amphitheater’ that focuses attention on the spectacularly three-dimensional mechanical architecture. The smooth pebble-like case measures 38 mm and is just 12 mm thick, making it the most compact MB&F; watch to-date. The front and rear sapphire crystals are cambered to blend seamlessly with the case, giving the SP One the feel of a polished stone. Visually, the smoothness is emphasised by lugs that ...

Auctions: A.-L. Breguet to F.P. Journe at Christie’s Geneva

Rare Watches in Geneva kicks off the spring auction season for Christie’s. Some of the highlights amongst the sale’s 183 lots illustrates the history and evolution of horology, most notably with timepieces by Abraham-Louis Breguet and Francois-Paul Journe. The notable F.P. Journe offerings include a Resonance pre-souscription and a Ruthenium full house, complete with numbered box. The standouts from Breguet include a pocket watch first owned by Pauline Bonaparte, Napoleon’s younger sister, an early striking carriage clock, and an intriguing Type XX precursor literally gone askew. F.P Journe Principally inspired by the work of A.-L. Breguet and Antide Janvier, Francois-Paul Journe’s landmark Chronomètre à Résonance was the first attempt at synchronised, coupled oscillators in a wristwatch. The first numbered 20 examples were reserved for a Breguet-style souscription series – paid in advance by the client – but were not the first made. Image – Christie’s A handful of pre-production watches were made for Basel 1999, followed by the pre-souscription series to which this watch belongs. About 20 watches starting from “21” onwards are pre-souscription, and this is “041/00R”. Notably, one example prior, “040/00R”, sold for a little under CHF1.4 million including fees at Christie’s in 2023, setting a record.

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...
