First Look – The new Kallinich Claeys Einser Zentralsekunde Voyager Edition

Founded by former A. Lange & Söhne watchmakers Johannes Kallinich and Thibault Claeys, indie watchmaking atelier Kallinich Claeys has quickly become one of the most interesting names in contemporary Glashütte watchmaking. Their debut watch, the Einser Zentralsekunde, introduced a clear design approach and a thoughtfully constructed, in-house movement with central seconds and a linear power reserve […]

Introducing – The All-New Moritz Grossmann Perpetual Calendar

One of the founding fathers of watchmaking in Glashütte, together with F.A. Lange, Moritz Grossmann also established the German School of Watchmaking. This important name returned in 2008, when trained watchmaker Christine Hutter founded a manufacture of classically German, high-end watches. For its 17th anniversary, the brand is about to release a first: a watch […]

Hands On: Breguet Four-Minute Tourbillon No. 1890 SJX Watches
Breguet Four-Minute Tourbillon No 1890 Nov 7, 2025

Hands On: Breguet Four-Minute Tourbillon No. 1890

In the coming weekend, one of the most important watches of this auction season will go under the hammer at Sotheby’s Breguet’s 250th anniversary thematic sale November 9 – Breguet no. 1890, a pocket watch with tourbillon and natural escapement made by the firm by Breguet while Abraham-Louis Breguet himself still helmed the company. The gilt dial with a regulator-style layout might seem familiar – the recent Classique 7225 reproduces this dial design. In fact, Breguet no. 1890 isn’t the only watch in this style; it belongs to a series of pocket watches all equipped with a four-minute tourbillon and échappement naturel from the early 19th century that were among the finest watches of the time. Breguet built just eight four-minute tourbillons with natural escapement, all of which thankfully survive, and only three with gold dials. King George III ordered the most famous example – almost identical to this watch – during the Napoleonic wars. For context, that would be like Churchhill (who owned a Breguet himself) ordering an A. Lange & Söhne watch during the Second World War. As such, it was signed Recordon, Breguet’s London agent, to disguise its French origins. Whirling About Regulator Almost 225 years ago, the French Ministry of the Interior granted A.-L. Breguet a patent for his most famous creation, the tourbillon – a clever exercise in lateral thinking. For a mechanical watch to keep the same time across all vertical positions the combined balance, st...

Hands On: Vacheron Constantin Tribute to The Quest of Time SJX Watches

Hands On: Vacheron Constantin Tribute to The Quest of Time

Vacheron Constantin (VC) marks its 270th anniversary this year in grand style with La Quête Du Temps, a monumental, multi-complication clock weighing over 150 kg. A little more wearable is the Métiers d’Art Tribute to The Quest of Time, also a 270th anniversary edition but in wristwatch format. Like many of VC’s high complicated watches, Tribute to the Quest of Time is a double-faced wristwatch. On the front is a double retrograde time display that’s either on demand or en passant, which takes the form of a human figure whose arms tell the time. Also on the front is a spherical moon phase, while the back is home to an astronomical display comprising a sky chart and sidereal day indicator. Initial thoughts Tribute to the Quest of Time is a big complicated watch, and it looks and feels the part. In terms of dimensions and feel, it reminds me a little of the Lange Repeater Perpetual Calendar that was also launched this year. Even though small watches are on trend now, complicated watches like this should be large. This succeeds in that respect, and feels good on the wrist. Despite the mechanical complexity, the time is easy to read, though it takes a moment to get used to the twin scales for the time. The symmetrical dial on the front is straightforward and legible. The dial is tinted sapphire and etched with the constellations in the night sky over Geneva on the day VC was established, September 17, 1755. This is not obvious at a distance but reveals itself up close...

The 25 Best World Time Watches (2026) Teddy Baldassarre

The 25 Best World Time Watches (2026)

Any listing of the best world time watches on the market today is best prefaced by explaining the difference between this type of travel watch and the more common GMT watches category. Whereas a GMT watch is designed to simultaneously display the time in both a traveler's local time zone and his or her home time zone, a world-time watch allows its wearer to quickly glimpse the time in numerous other time zones across the world in addition to the local and home time, often in visually spectacular fashion with globe-themed dial designs. Here we've found 25 world-time watches that are worthy of your notice, with price tags ranging from eminently affordable (Tissot, Ball, Nomos) to exclusive and expensive (Breguet, Vacheron Constantin, Patek Philippe). Unlike our roundup of GMTs, we didn't disqualify watches with additional complications but we did err on the side of watches more recently introduced to the market. And you'll be happy to discover a few of them that you can purchase directly from our online store. (In the case of the limited editions showcased here, some of which may now be available only on the secondary market, prices listed reflect the MSRP at the time of release.)  A. Lange & Söhne Lange 1 Time Zone Price: On Request, Case size: 41.9mm, Thickness: 10.9mm, Lug Width: 22mm, Crystal: Sapphire, Water Resistance: 30 meters, Movement: Manually Wound L121.3 The now-iconic Lange 1 has been the flagship of the reconstituted A.

Ulysse Nardin’s Blast Free Wheel Dressed in German Silver SJX Watches
Ulysse Nardin s Blast Free Wheel Jul 16, 2025

Ulysse Nardin’s Blast Free Wheel Dressed in German Silver

Ulysse Nardin presents a surprisingly striking new version of its most forward-thinking tourbillon, the Blast Free Wheel Maillechort. An interesting blend of classic finishing and bold, three-dimensional architecture, the limited edition piece is unlike the generally future-forward aesthetic pushed by Ulysse Nardin in recent years. The latest Blast Free Wheel retains the novel movement construction with elevated moving parts and a constant force mechanism integrated inside the tourbillon, but now set against a traditional, grained plate in maillechort, or German silver. Initial thoughts The Free Wheel is a long established collection, having been rolled out in several case styles over time, but this new incarnation is arguably the best one yet. The Le Locle-based brand is known for its overall loud designs and its tendency to push a very modernist look, so the old-school approach with maillechort is unexpected but appealing. The Blast Free Wheel still retains a somewhat loud case design, but the modernism here is more restrained and the futuristic movement is toned down by its finishing. As the name suggests, the main point is maillechort, a brass alloy better known as German silver. Long employed in historical watches, the material is usually associated with classic timepieces from the likes of A. Lange & Söhne or artisanal watchmakers, but here it compliments the avant-garde movement well. The soft silver-grey hue of the German silver serves as an excellent backdrop for...

DUG: The New Kids on the Block in Glashütte

On a warm and sunny Saturday in June, I visited the inauguration ceremony for DUG workshop. DUG (Deutsche Uhrenmanufaktur Glashütte) is the eleventh company to establish itself in the watchmaking town of Glashütte. The last brand to open a workshop in this town were young independent duo, Kallinich Claeys.  The DUG workshop is just around the corner from Lange HQ, across from Glashütte Watch Museum, and on the steep road leading up to one of Nomos’s workshops. The building previously belonged to C.H. Wolf, and there is still some old signage around the building. It is a modern and fairly large building for a micro-brand to occupy. It has tall ceilings and a row of new watchmaker benches along with a few administrative and conference rooms. It could easily host a medium size watch company. The DUG workshop Toni Brodführer, founder and Managing Director of DUG, is planning to move in there before the end of the year with three watchmakers. He is also open to sharing the space with other small watch companies. At the opening ceremony, I was pleased to run into Thibault Claeys and Johannes Kallinich, who were impressed by the building and seemed to like what Toni is doing. Before I get back to my observations about the brand and the newest watches, I interviewed Toni to get some background and context of owning and operating a new micro-brand in Glashütte.  Toni’s journey of DUG began with a personal passion for watches. He had been fascinated with watches since his...

Watch Collector’s Week 2025 at Isetan Shinjuku in Tokyo

Perhaps the most storied department store in Japan – and still one of the highest grossing in the entire world – Isetan Shinjuku is staging its annual Watch Collector’s Week from July 2-22, 2025. Being in Japan, where everything is pursued in a serious minded manner, the theme of the event is “Astronomy and Timekeeping”. And in typical Japanese fashion, the event also has an accompanying manga, or Japanese comic book. The event encompasses both watches on show as well as historical displays and talks. Participating brands range from establishment names like A. Lange & Söhne and Tudor to independent watchmakers including H. Moser & Cie. and Ressence. Several brands will debut Isetan-exclusive limited editions, including Grand Seiko and Kudoke. The Christiaan van der Klaauw Grand Planetarium Eccentric. Image – Shellman One of the highlights of the event is the exhibit of Shellman, the Tokyo-based independent watch retailer that has concessions in Isetan Shinjuku and other prestigious department stores. Shellman’s display is centred on Christiaan van der Klaauw, the longtime specialist in astronomical watches, as well as Hermle, the German clockmaker that produces various clocks with astronomical displays.

Watches & Wonders Announces 2026 Dates

Anchored by brands like Rolex, Patek Philippe, and Cartier, Watches & Wonders (W&W;) is the world’s biggest luxury watch fair  and it will take place at its traditional time of early spring, April 14-20, 2026, once again at Palexpo. As is now convention, the final three days, April 18-20, will be open to the public, who can access the fair by buying a ticket. The first four days will only be open to invited guests, namely members of the trade, primarily brand executives, retailers, media, as well as select clients. W&W; will also stage events outside Palexpo, the convention centre near the airport, with several events planned in downtown Geneva. In past years, these have included exhibitions, talks, and social gatherings. The exhibitors for 2026 have yet to be announced, but the establishment brands are a certainty, including the brands owned by Richemont like A. Lange & Söhne and Vacheron Constantin, and the LVMH marques like TAG Heuer and Hublot. There has been talk of brands joining (or returning to) the list of exhibitors – Bulgari was a newcomer in 2025 – but this will soon be known once W&W; publishes the exhibitors directory.

Visit: A Look Inside Biver Watches

The day I visited Biver started like any other – with breakfast. But it wasn’t a normal breakfast, because I was seated opposite Jean-Claude Biver, at his own kitchen table. A few days after Watches & Wonders wrapped up I had the opportunity to visit the brand’s atelier in the countryside near Geneva, and I was lucky enough to spend some time with the man himself before he went to the airport; he was headed to Boston to deliver a guest lecture at Harvard Business School. Dismissed in his early career as a ‘nostalgia salesman,’ Mr Biver helped pioneer the contemporary luxury watch industry in the midst of the Quartz Crisis by proving the consumer demand for artisanal mechanical watches. The story is well-known but it bears repeating; Mr Biver, together with his friend Jacques Piguet, head of the esteemed Frederic Piguet manufacture, paid CHF22,000 to buy the rights to a defunct brand from what would later become Swatch Group. Their deft products and marketing made Blancpain one of the stars of the mechanical watch renaissance, allowing the pair to sell the brand back to Swatch a decade later for CHF60 million. From left to right: CEO James Marks, Jean-Claude Biver, and Pierre Biver. Image – Biver The success of Blancpain was extraordinary and helped pave the way for the rebirth of other brands like A.

Highlights: Phillips NYWA XII

As the Hong Kong auctions have wrapped, we move to the final sales of the spring season in New York City. Phillips will offer a healthy mix of new and old, common and rare, across 144 lots. The sale includes many of the expected top-of-the-line offerings, with the headline lot a Patek Philippe ref. 1518 in yellow gold, and staples like a pair of ref. 5004s. But there are plenty of interesting watches to be down catalog too, including some fresh faces and value buys. Highlights include the best of English watchmaking made by Charles Frodsham a century apart, the auction debut of American independent Keaton Myrick, an unusual F.P. Journe Résonance, along with a Cartier pocket watch made by complications specialist THA. We round up these and a few more from The New York Watch Auction: XII, which takes place from June 7-8, 2025. The full catalogue is available on Phillips.com. Lot 11 – A. Lange & Söhne 1815 Chronograph “2022 Best of Show, Concorso d’Eleganza Villa d’Este” Since 2012, A. Lange & Söhne has been a sponsor of the Concorso d’Eleganza Villa d’Este, a classic car shown that takes place in spring on the picturesque shores of Lake Como. Each year, the owner of the event’s best car is presented with a unique Lange watch. While past winners have received a fairly conventional Lange 1 Time Zone, the brand upgraded the prize in recent years to a striking 1815 Chronograph. In 2022, the winner was Andrew Pisker with a Bugatti 57 S from 1937. He received th...

Highlights: Complicated Watches at Phillips Hong Kong

Phillips’ upcoming Hong Kong auction encompasses excellent complications at a range of price points. Highlights at the top end include the controversial Patek Philippe ref. 3448 “Senza Luna”, a massive Jaeger-LeCoultre exotic tourbillon, a skeletonized Credor chronograph, and a special-order Patek Philippe that was presumably a gift from parent to son. Also on the block are fine pocket watches for the Chinese market on the first day of the sale, while the second and third sale days include notable examples of independent watchmaking. The Hong Kong Watch Auction: XX takes place from May 23-25, 2025. The full catalogue, and more, is available on Phillips.com. Lot 839 – A. Lange & Söhne Triple Split In 2004, A. Lange & Söhne introduced the Double Split, a chronograph with both split-seconds and split-minutes–a feat previously only accomplished in pocket watches. Never one to stand still, Lange added split-hours into the mix with the Triple Split in 2018. The case is the brand’s typical fare, with distinctive stepped-out lugs, and continues its tradition of placing the split-button in the case band, rather than in the crown, as is the convention for wristwatches. This rose gold variation, of which only 100 were made, is matched with a handsome blue and silver dial. To create the Double Split, Lange built on the landmark L951 movement of the Datograph, adding a pair of rattrapante mechanisms, one for seconds and the other, minutes. From there, Lange added an hour...

Nomos Watches Review Teddy Baldassarre
Nomos Apr 27, 2025

Nomos Watches Review

In its relatively young existence, Nomos Glashütte has become one of the most popular and successful German watch brands as well as probably the most accessible to newer (and younger) collectors. Nomos’s success - which includes an impressive string of German design awards - has resulted from a combination of sensible pricing, classical Bauhaus design, and creative forays into color, with a bit of mechanical innovation thrown in for good measure. Read on for an in-depth look at today's Nomos Glashütte collection, along with some background on the brand.  A Rebirth in Glashütte It was just two months after the Fall of the Berlin Wall, in January 1990, when Roland Schwertner, a photographer and tech-savvy entrepreneur from Düsseldorf, founded Nomos in the East German town of Glashütte, deriving its name from the Ancient Greek god of law. Before World War II and the subsequent Cold War that partitioned Germany into two nations, the town (above), outside of Dresden in the state of Saxony, was a world center of watchmaking. The foundation of Nomos - along with the revival of historical watch brands like A. Lange & Söhne and the evolution of the conglomerate known as Glashütte Original into a luxury watchmaker - spearheaded the rebirth of Glashütte’s horological heritage in the new, reunited Germany.  What set Nomos apart from most of the other manufacturers in Glashütte, then as now, is the company’s clean, modernist aesthetics as well as its relatively...

Kallinich Claeys Brings Creative Independent Watchmaking to Glashütte

In the Fall of 2023, I organized a RedBar event in Prague for Marco Lang, Stefan Kudoke, and Jochen Benzinger. During the event I met two young guys who looked in their early twenties, enjoying fresh Pilsner beer. When we raised our glasses to cheer, I noticed his wrist and had a hard time believing what I saw.  The young man introduced himself as Thibault Claeys and said this is their first watch. The other young man introduced himself as Johannes Kallinich. While I looked at the watch, Thibault told me that both of them worked at A. Lange & Söhne until recently. Johannes was the head of the Lange 1 department and a certified Master Watchmaker with a deep understanding of technical construction. Thibault, on the other hand, graduated from watchmaking school in Antwerp, and joined the Lange 1815 department. His expertise lies in finishing techniques, and he plays MacGyver with all the machines and tooling.  The next encounter with Thibault and Johannes was a planned visit to their atelier in the summer of 2024. Their small workshop is located right next to Nomos headquarters, and directly opposite from the SUG case workshop in Glashütte. The workshop is framed all around by large windows, an inspiration they took from Akrivia and Rexhep Rexhepi.  Thibault walked me through “his side” of the workshop first where he built his own CNC milling machine. You see all the contraptions he built himself for making parts or for finishing of the parts. He says it actually all...

Christie’s to Sell Single-Owner Collection of 21st Century High Horology

Christie’s is continuing with its streak of single-owner watch collections into the 2025 season with Stories in Time. Made up of 160 watches – including a sizeable number of independents – the sale is the culmination of three decades of collecting by one collector. Representing 47 brands from A. Lange & Söhne to Voutilainen, the collection represents 21st century horology in all its diversity, capturing the evolution of contemporary watchmaking as it developed from the 1990s onwards. The watchmaking landscape Establishment brands like Patek Philippe and Vacheron Constantin are well represented, but equally the independent watchmakers and brands out of the mainstream. While the brand with the largest number of pieces in the collection is Patek Philippe at 20, the second most numerous brand is De Bethune at 18. The line-up also includes nine watches by Greubel Forsey and seven from MB&F;, as well as a few examples of the Harry Winston Opus series. One of the nine Greubel Forsey watches in the sale, the Double Tourbillon 30° Edition Historique in platinum with an estimate of US$120,000-220,000 Almost every watch in the collection is in pristine condition and accompanied by the original boxes and paperwork, reflecting the collector’s meticulous approach. This collection will be offered at Christie’s sales across the world over the course of 2025, in Hong Kong, Dubai, Geneva, and New York in the eight auctions during the spring and autumn sales.

Insight: Regulating a Mechanical Watch Movement SJX Watches
Patek Philippe Mar 7, 2025

Insight: Regulating a Mechanical Watch Movement

A mechanical watch is not always spot on; less-than-perfect timekeeping can happen, often due to an unruly oscillator. The solution is direct adjustments to the hairspring and balance assembly, either slowing down or speeding up the oscillator, a practice known as regulation. Watchmakers have devised multiple innovations to achieve this, including the free-sprung balance, exemplified by the Gyromax of Patek Philippe and Microstella of Rolex. While a simple concept in principle, the mechanics and practice of regulation are nuanced. Here we’ll delve into the theory of regulation and the primary regulating systems: the curb-pin regulator and the free-sprung (or variable inertia) balance. The Lange L043.4 with a screwed balance inspired by pocket watches Basic concepts In order to better understand watch regulation, we need to first cover some of the basic physics behind the watch oscillator: The component responsible for the running rate of a movement is its regulating organ. The regulating organ is made up of a hairspring paired to a balance, which together are also known as a harmonic oscillator. The natural oscillation period is the time it takes the balance to make a full swing, back and forth. The period is made up of two vibrations, one for each direction of the balance motion, with the escapement being unlocked at each vibration. Notably, the natural period of a balance wheel is intrinsic to itself and does not depend on the escapement type or the going train ratio. ...

Robert Greubel, Stephen Forsey Consolidate Control of Greubel Forsey

Greubel Forsey has just announced that ownership of the company has once again reverted to Robert Greubel and Stephen Forsey, confirming rumours that have been circulating since Michel Nydegger replaced Antonio Calce as chief executive. With Mr Calce’s departure, the brand was pivoted back to more traditional complicated watches, as exemplified by the recent Hand Made 2 and Nano Foudroyante EWT. The shares owned by Mr Calce, was acquired by either the two cofounders or the company itself. The statement issued by Greubel Forsey states “Mr. Calce no longer holding any shares in the company or being affiliated with it.” Mr Calce came on board in 2020, and redirected the brand towards high-end sports watches. Industry talk at the time was that he was not only pivoting the company’s products, but also engaged in a search for a buyer for the brand. With a majority stake, Mr Greubel continues as the board’s chairman. Though his exact role is unspecified, Mr Forsey will presumably take off where he left off, as both a brand ambassador and watch constructor. The return of the two founders as the company’s only shareholders is the latest twist in the story of the company. Besides Mr Calce, Richemont once owned a stake in the brand. The Swiss luxury group, which also owns Cartier and Lange, acquired 20% of the brand in 2006 but the hoped-for synergies or acquisition never came to pass. Richemont sold the stake back to Greubel Forsey in 2022 , just after Mr Calce came on b...

Best of 2024: Complications SJX Watches
Vacheron Constantin Dec 23, 2024

Best of 2024: Complications

Perhaps echoing the paucity of highlights in indie watchmaking, the best complications of 2024 were not numerous, but those that stood out were outstanding. Vacheron Constantin, for instance, unveiled the most complicated watch ever, while Bovet solved the longstanding problem of summer time across continents in an enormous (and enormously expensive) wristwatch. Here’s the team’s take on the best complications of the year. A. Lange & Söhne Datograph Handwerkskunst – Brandon Moore The iconic Datograph turned 25 this year, and collectors were treated to three different limited edition variants to mark the occasion. We were first introduced to the Datograph Perpetual Tourbillon Honeygold “Lumen” and the Datograph Up/Down 25th Anniversary at Watches & Wonders, but Lange was arguably saving the best for last: the first Datograph to receive the brand’s artisanal Handwerkskunst treatment. Featuring a hand-engraved tremblage dial and limited to just 25 pieces, the Datograph Handwerkskunst is a fitting way to celebrate a quarter-century of being best-in-class. While not particularly creative, this very-limited edition captures both the magic of Lange and its Datograph perfectly. Bovet Récital 28 Prowess 1 – SJX The introduction to our story on the watch sums it up best: “The Bovet Récital 28 Prowess 1 is an ingenious solution to an age-old problem: accounting for daylight saving time (also known as summer time) in a multi-timezone wristwatch… the solution is e...
