Introducing the F.P. Journe Astronomic Blue for Only Watch 2019 SJX Watches
F.P. Journe Astronomic Blue Jul 1, 2019

Introducing the F.P. Journe Astronomic Blue for Only Watch 2019

A young Francois-Paul Journe created his sixth ever watch in 1987; it was an “astronomic planetary watch”, a pocket watch with faces on each side. Over three decades later that has been reimagined as the Astronomic Blue, a prototype grand complication made for Only Watch 2019. Mentioned by Mr Journe in an interview late last year, the Astronomic Blue is a hand-wound wristwatch with astronomical functions on two faces, as well as a minute repeater and tourbillon with remontoir d’egalite. The complications total 18, and are powered by a movement made up of 758 parts, making it more complex than the Sonnerie Souveraine. The astronomic planetary watch of 1987, signed “Journe à Paris” Like the preceding F.P. Journe watches made for Only Watch, namely the tourbillon and split-seconds, the Astronomic Blue has a tantalum case and mirrored blue dial like that found on the Chronometre Bleu. The case is 44mm in diameter and 13.75mm high, making it comparable in size to the discontinued Sonnerie Souverain and recent Tourbillon Souverain Vertical. Remembering 1987 As with many of Mr Journe’s early creations, the pocket watch was inspired by both Abraham-Louis Breguet and George Daniels, a quality that is echoed in the Astronomic Blue. Like the George Daniels Space Traveller, the front shows sidereal and mean solar time on two symmetrically arranged sub-dials, while the reverse has a ring-type annual calendar and equation of time indicator, which is reminiscent of the...

In-Depth: Understanding Resonance in Watches SJX Watches
F.P. Journe s Chronomètre à Résonance Feb 19, 2026

In-Depth: Understanding Resonance in Watches

Resonance watches are among the most elusive machines in modern watchmaking. Creations such as F.P. Journe’s Chronomètre à Résonance perform well at auctions, commanding high prices. While their rarity and appeal are undeniable, watches that purport to harness resonance tend to be viewed with a degree of skepticism. A measure of skepticism is understandable - the concept of sprung balances becoming almost magically coupled is anything but straightforward and requires a profound understanding of oscillators in general.   This story seeks to shed some light on the concept of coupled oscillators by explaining the two models of coupling and explore the nuances of each system. Before exploring resonance, the reader is encouraged to review the basics of sprung oscillators and isochronism in order to become more familiar with the hairspring and balance wheel model.  The F.P. Journe Chronomètre à Résonance Souscription No. 2 sold for more than CHF3 million in November 2025. A confusion of terms First, the term resonance itself requires definition. In classical physics (mechanics, electrical engineering, signal processing, etc.) resonance is a phenomenon where a system vibrates under the influence of an external driving force that matches the system’s eigenfrequency (natural frequency). This is to say that a system at rest, which includes mass and spring elements, can be excited into a state of resonance by an external force when particular conditions are met. An imp...

Hands On: Barbier-Mueller Mosaïque II SJX Watches
F.P. Journe Chronometre Souverain May 6, 2024

Hands On: Barbier-Mueller Mosaïque II

One of the most esoteric offerings in Only Watch 2024 is the Barbier-Mueller Mosaïque II. A follow-up to the first edition made in 2017, the Mosaïque II sticks to the same template that was originally inspired by a 19th century pocket watch with an inlaid case. It’s essentially an F.P. Journe Chronometre Souverain with a slightly larger case inlaid with semi-precious stones and a hinged hunter back. This also makes F.P. Journe the only brand with two watches – the other is the Chronomètre Furtif Bleu – in the upcoming charity auction that takes place on May 10, 2024. Initial thoughts I liked the original version because it was recognisable as an F.P. Journe watch, yet entirely different. The Mosaïque II holds the same appeal, albeit at a far higher price given the increased demand for F.P. Journe in the years since. While in 2017 one could reasonably hope to buy the first Mosaïque for a high five-figure price – in fact it sold for a trifling CHF90,000 – the Mosaïque II will almost certainly end up in the high six- or even seven figures. Affordability aside, the Mosaïque II is a little more interesting than its predecessor because of the floral motif as well as the materials; the bloodstone inlays are a particularly striking backdrop for the other stones. The inlays are also more complex, with both the dial and back inlaid with stones in a mix of shapes and sizes.

Eight Collectors of Independent Watchmaking to Follow on Instagram SJX Watches
F.P. Journe tourbillon Akrivia Chronometre Contemporain May 25, 2020

Eight Collectors of Independent Watchmaking to Follow on Instagram

While the vast majority of watch content on Instagram is predictable and repetitive – hello Nautilus with baguette gemstone bezel and Submariner “Hulk” –  there are a couple of collectors with interesting watches who share their collections on the picture-sharing app. The most interesting for me are the independent-watchmaking enthusiasts. Most own watches that well known and regarded as landmarks in the genre – Philippe Dufour Simplicity, F.P. Journe tourbillon, Akrivia Chronometre Contemporain, and the like – but many also have watches further off the beaten track, like Keaton Myrick’s 1 in 30 or the Bexei grande sonnerie. Here are a few independent-watchmaking collectors who are worth a follow. @igwatchlover – A collector based on Southeast Asia, Igwatchlover features his own watches, as well as occasionally watches owned by his friends – who are also accomplished collectors. Amongst the watches that can be found on his account is the unique and elaborate Voutilainen Starry Night Vine, and the Vox Vinum grande sonnerie by Aaron Becsei, and the one-off, regulator-dial minute repeater by Voutilainen. And he also features a good number of notable complicated watches from the 1990s, which are overlooked today but often just as interesting as the latest creations. @horoptimist – A longtime collector who only started his Instagram account recently, Horoptimist is based in Asia but has managed to visit several independent watchmakers in their home count...

Up Close: Akrivia Rexhep Rexhepi Chronomètre Contemporain “Only Watch”

Independent watchmakers are a major presence at Only Watch 2019, accounting for almost half the 50 lots in the charity auction coming. Importantly, two of them will probably end up in the top five by value – the F.P. Journe Astronomic Blue and the Rexhep Rexhepi Chronomètre Contemporain “Only Watch”. While the Astronomic Blue is the most complicated wristwatch F.P. Journe has ever made, the Chronomètre Contemporain “Only Watch” is a time-only watch, with a suitably modest estimate of 40,000-60,000 Swiss francs, though it’ll probably sell for five to seven times the low estimate. Hammered, and enamelled The key element that sets the “Only Watch” edition apart from the standard Chronomètre Contemporain is the dial. Completely unique because of the technique – used here for the first time in an Akrivia watch – the dial combines the surfaces finish of Akrivia’s two distinct collections: the hand-hammered decoration of the contemporary AK line and the vitreous enamel of the classic Rexhep Rexhepi range, named after the brand’s founder. Several attempts were required to get a perfect dial – Rexhep showed me one of the rejects with a cloudy finish in September – but the result is quietly impressive. Note that it is hammered and then enamelled, but not hammered enamel. Ordinarily a new dial colour doesn’t mean very much, but because the Chronomètre Contemporain regarded, and Rexhep has kept his promise not to do variations or custom orders of th...

F.P. Journe Introduces the Chronomètre Furtif SJX Watches
F.P. Journe Introduces Mar 31, 2025

F.P. Journe Introduces the Chronomètre Furtif

As is tradition for F.P. Journe, the unique creation made for the most recent Only Watch has now evolved into a regular production watch, the Chronomètre Furtif, that has the same dimensions and movement, but an entirely different material and style. The Chronomètre Furtif is striking, all-black sports watch that is almost entirely in tungsten carbide, a hard and strong material typical used for tooling. The furtif, or “stealthy”, aspect is enhanced by the tone-on-tone fired enamel dial in dark grey with laser engraved markings that are primarily visible to the wearer. Initial thoughts The Chronomètre Furtif is expected because of the Only Watch edition that came before it – and because Francois-Paul Journe has talked about it – but it is novel amongst F.P. Journe watches for the all-black look. That said, it is still recognisable as an F.P. Journe as it inherits many elements from the lineSport. In the hand, the Chronomètre Furtif is almost entirely black at many angles, though the mirror-like dial is highly reflective. And it is impressively heavy at some 250 g, though it sits well because the case is wide and flat. But most of all, the low-key look is arguably all the more appropriate given the fame of the maker and the desirability of his watches. At this moment in time I would absolute love a furtif F.P. Journe rather than a highly recognisable model like the Elegante or Chronomètre Bleu. The cal. 1522 inside Stealth and l0w-key The Chronometre Furtif ret...

Barbier-Mueller Returns with the Mosaïque II SJX Watches
F.P. Journe Chronomètre Souverain movement – Jun 29, 2023

Barbier-Mueller Returns with the Mosaïque II

In 2017, the original Barbier-Mueller Mosaïque made its first public appearance at Only Watch. The collaborative efforts of longtime friends Stéphane Barbier-Mueller and François-Paul Journe, one being the preeminent independent watchmaker and the other a member of one of a Swiss real estate dynasty, this was an unexpected and rather pleasant surprise. Now, the pair have returned with the Mosaïque II, follow up to their initial offering, sticking to the same principles as before, but with the eye of watch designer Eric Giroud.  Initial thoughts Those who are fans of the original will be pleased to see all of the main traits have been carried over to this latest version. The stone work on the dial, case and hinged caseback is all there, and the two hander runs on the F.P. Journe Chronomètre Souverain movement – in fact, it is essentially an elaborately inlaid Chronomètre Souverain. If anything, they have elevated their previous efforts by incorporating more types of semi-precious stones in order to execute Mr. Giroud’s design. While Mr Giroud’s eye has given the Mosaïque II a different feel from its predecessor, the new watch still reflects Mr Barbier-Mueller’s interest in arts and culture, which was the basis for the original Mosaïque. Besides being a shareholder in F.P. Journe, Mr Barbier-Mueller is also a member of the family that established the Barbier-Mueller Museum in Geneva that’s famous for its world-class collection of tribal art. The original M...

F.P. Journe Introduces the New Chronomètre à Résonance SJX Watches
F.P. Journe Introduces Apr 28, 2020

F.P. Journe Introduces the New Chronomètre à Résonance

Since its launch in 2000, the Chronomètre à Résonance has perhaps become the quintessential F.P. Journe wristwatch. Still the only wristwatch to rely on the principle of resonance – omitting any mechanical means of transmission – the Résonance has been revamped and improved for its 20th anniversary. While the Résonance was powered by essentially the same calibre (the cal. 1499 in several generations) for its first two decades, the new Chronomètre à Résonance is equipped with the brand-new cal. 1520. Several features set the new movement apart from its predecessor, most notably the use of a single barrel and a remontoir d’egalite constant force mechanism in each going train. Initial thoughts Having learnt a little about the new Résonance from hints dropped by Mr Journe in the past, I was looking forward to this – and the watch lives up to expectations. The basics of the new model are no surprise, since Mr Journe had let on that the movement will incorporate his signature remontoir. The upgrades to the new movement are sensible both in terms of function and timekeeping. Relying on a single barrel eliminates the finicky and occasionally unreliable double-barrel winding mechanism of the original movement. But the remontoir installed in each going train is the crucial upgrade as it optimises the going trains before and after the escapement. In the original Resonance movement, both balance wheels oscillate at an identical amplitude at any one time, but the am...

In Plain Sight: Revealing The Secrets Of F. P. Journe’s Resonance Chronometer

This story is something of a mea culpa. Many years ago, when I was yet green with youth and correspondingly filled with overweening self-confidence, an independent watchmaker –a respected one; a student of the work of such luminaries as Janvier and Breguet –named Francois Paul Journe, came out with a most intriguing watch. That watch was […]

Only Watch 2021: Independent Watchmaking Highlights

The top lots amongst independent watchmakers at Only Watch 2021 are no doubt the F.P. Journe FFC Blue and Rexhep Rexhepi Chronomètre Contemporain II, but they will cost six or seven figures. But half of the participants at Only Watch are independent watchmakers, so there are a few more interesting examples of the genre, which might possibly be reasonably affordable. We round up five notable watches amongst the “indies”, ranging from the quirky and fascinating Urwerk that’s an upgraded example of the brand’s earliest watch to the stunningly engine-turned Andersen Genève Quotidiana. Urwerk UR-102 “Gaïa” Perhaps the avant-garde independent watchmaker, Urwerk is best known for revolutionising the presentation of time, having invented time displays using satellite cubes on a carousel and prisms in cylinders. But the brand’s creation for Only Watch 2021 looks nothing like its recent work, because it’s a quarter-century old, an artefact from the brand’s start-up days. The UR-102 “Gaïa” is a prototype of one of the brand’s earliest models – it is actually a vintage Urwerk – but dressed up smartly for the occasion, with a special case back decoration that signifies the brand’s success. The platinum case back is adorned with a sparkling, deep blue emblem that alludes to the Gaïa Prize, which Urwerk’s founders won in 2020 That said, being an Urwerk, the time display is far from rudimentary. While neither a cube nor a prism, it is still a wond...

Insight: F.P. Journe Répétition Souveraine Smoked Sapphire SJX Watches
F.P. Journe Répétition Souveraine Smoked Sapphire Dec 16, 2025

Insight: F.P. Journe Répétition Souveraine Smoked Sapphire

The Répétition Souveraine is one of the more unusual minute repeaters on the market, combining classical inspiration with an idiosyncratic technical approach that is unmistakably F.P. Journe. Based on the familiar architecture of the Chronomètre Souverain yet fundamentally reworked to accommodate a striking mechanism, it is neither a conventional integrated repeater nor a simple modular add-on. Launched in 2008 with a conventional dial and briefly the thinnest contemporary minute repeater on the market, the latest iteration of the Répétition Souveraine reveals its workings through a smoked sapphire dial, offering a direct view of its flat gongs and strike train while underscoring François-Paul Journe’s distinctive philosophy of clarity, compactness, and mechanical logic. This is our third encounter with the Répétition Souveraine, having already covered the silver-dial variant and the elusive “Black Label” edition. Almost modular Most independents – and many large brands – rely on a handful of external specialists like Le Cercle des Horlogers or decades-old ebauche stocks for their repeaters. As a result, most repeaters take the same, time-tested, approach with only a few exceptions. Most are integrated designs that put the repeater train, hammers, and gongs on the same level as the rest of the movement. The rejuvenation of mechanical matchmaking during the 1980s and 1990s brought with it demand for systems that brands could add to existing movements. Amo...

Unique F.P. Journe Resonance Raises US$2.98 Million for Charity SJX Watches
F.P. Journe Resonance Raises US$2.98 Million Nov 28, 2024

Unique F.P. Journe Resonance Raises US$2.98 Million for Charity

For its third outing supporting the Prince Albert II of Monaco Foundation, F.P. Journe created a unique Chronomètre à Résonance that sold for S$4.00 million – equivalent to US$2.98 million – during the charity’s annual gala dinner in Singapore. As a friend of the Monegasque ruler, François-Paul Journe has long supported his namesake charity. Now once of the most valuable recent F.P. Journe watches ever sold, the Resonance follows the LineSport Rattrapante of 2018 and the Chronometre Optimum of 2022, which have cumulatively raised several million for the charity that supports environmental causes around the world. Echoing the livery of the Optimum of 2022, the unique Resonance has a platinum case with a burgundy dial and ruthenium sub-dials. Notably, two forms of Chinese characters: modern simplified Chinese characters on the right sub-dial, while the left register has markings in oracle bone script, the oldest form of written Chinese. The movement is engraved on the barrel bridge: “S.A.S. Albert II Singapore 2024” More than double the result of the Optimum in 2022, the big number for the Resonance is no surprise given the recent record-setting sale of the 1993 F.P. Journe tourbillon prototype. This arguably demonstrates that F.P. Journe has gone beyond a watchmaker or even watches, but a brand. This desirability of the F.P. Journe brand is reflected in not just the value, but how easily and quickly it was achieved at the auction during the dinner event. Thoma...

Auction Watch: A Single-Owner Collection of F.P. Journe at Phillips

Le Concours de Complexité is probably the smallest watch auction ever conducted by Phillips. Taking place online from January 13-20, the sale comprises just 11 watches. But all 11 are F.P. Journe watches, including important models like a Sonnerie Souveraine, Chronomètre à Résonance Ruthenium, and Centigraphe Anniversaire. So while the quantity is modest, the quality and value are high. And the watches all come with impeccable provenance. The former owner is a prominent businessman from Southeast Asia who is active real estate development. He purchased most of them brand new and has clearly kept them in immaculate condition. Le Concours de Complexité begins on January 13 and will run until January 20. Bidding and the catalogue can be accessed on Phillips.com. Below we round up a trio of highlights from the sale. The Sonnerie Souveraine Lot 8001 – Chronomètre à Résonance Ruthenium Synonymous with the independent watchmaker, the Resonance is correctly regarded as one of the most ingenious creations in contemporary watchmaking. Francois-Paul Journe was the first to implement the concept in a wristwatch, having been inspired by 18th century clocks operating on the principle of resonance. This example is one of the Ruthenium series that was launched in 2001. The name comes from the fact that the dial and brass movement bridges are plated in ruthenium, giving them a dark grey finish. Notably, the Ruthenium editions are the last F.P. Journe models to utilise brass m...

F.P. Journe Introduces the Astronomic Souveraine Grand Complication

Just days after the F.P. Journe Astronomic Blue made for Only Watch 2019 sold for a record 1.8m Swiss francs, the watchmaker has unveiled the regular production version of the same – the Astronomic Souveraine. While the last unique F.P. Journe produced for Only Watch eventually made into production in a significantly different form, the Astronomic Souveraine is largely the same. Save for the steel case, dial colours, and movement decoration, the Astronomic Souveraine is identical to the unique Only Watch creation. Inspired by a pocket watch Francois-Paul Journe produced in 1987 – itself inspired by the earlier works of Breguet and George Daniels – the Astronomic Souveraine has 18 complications, shown on two faces on each side of the case. These include showing both mean solar time and sidereal time, as well as an annual calendar, equation of time, tourbillon with remontoir d’egalite constant force mechanism, and a minute repeater. Despite its complexity, the indications are remarkably well-presented, and furthermore, can all be adjusted via a single crown. Though the case is 44mm wide – the largest wristwatch ever by F.P. Journe – it remains notably compact at just 13.8mm high, helped in part by his ultra-thin minute repeater mechanism with flat hammers and gongs. As with most F.P. Journe watches, the dial on the front is solid gold, as are the bridges and plate of the movement. The 758-part cal. 1619 is equipped with double barrels, which are partly visible ...

Home-Made Grande Sonnerie Wins 2026 F.P. Journe Young Talent Competition SJX Watches
F.P. Journe Young Talent Competition Shin Apr 27, 2026

Home-Made Grande Sonnerie Wins 2026 F.P. Journe Young Talent Competition

Shin Ohno is the winner of the 12th F.P. Journe Young Talent Competition. The young Japanese watchmaker clinched the prize with the Fuyu-Geshiki, a small grande et petite sonnerie tourbillon clock inspired by the winter landscape of Nagano, a northern prefecture of Japan. Made by one man with a watchmaker’s lathe, desktop CNC mill, and not a lot of sleep, the ebony-cased timepiece is one of the most impressive works produced by the competition yet. From Nagano Mr Ohno describes Nagano as “defined by the purity of its air, by the flow of spring water, and by melting snow”. It is also the heart of Japan’s watch industry, boasting the country’s largest movement assembly plant (Citizen’s Saku plant) and is home to Mr Ohno’s employer — Seiko Epson. Specifically, Mr Ohno works as an engineer within the company’s watch division, but it should be noted that this timepiece is entirely unrelated to the (now discontinued) Credor Spring Drive Sonnerie and Credor Minute Repeater. Mr Ohno designed the movement from the ground up, citing the creative works of past winner Norifumi Seki and Masahiro Kikuno as key inspirations. A closer look at the tourbillon cage. The teeth are polished to catch the light like slick stones. While he learned how to design watch parts at his day job, it was someone else’s job to manufacture them. With the Fuyu-Geshiki, Mr Ohno had to master production as well as design. He cites his colleague, master watchmaker Ikukiyo Komatsu, as a mento...
