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...

Insight: Daniels’ Co-Axial Escapement, an Evolution of the Fasoldt Chronometer SJX Watches

Insight: Daniels’ Co-Axial Escapement, an Evolution of the Fasoldt Chronometer

In the quest for precision chronometry in a mechanical watch, perhaps no other component is as crucial as the escapement – often consisting of an escape wheel and lever that engage with the oscillating organ. The history of watchmaking recounts many an attempt at inventing a better-performing escapement, with some attempts naturally more successful than others. By the 20th century, the watch industry had settled upon the Swiss lever escapement, which has proven itself to be a reasonably solid performer and crucially, one fit for mass production. However, in the latter decades of the century, one English watchmaker attempted to challenge the industry status quo. In 1974, George Daniels invented the “co-axial escapement”, a seemingly novel and practical escapement of his own design that was conceived as an functionally superior alternative to the Swiss lever escapement. Daniels’ invention fulfilled his ambition, at least in part, when it was sold to Omega and then successfully industrialised starting in 1999; today it is found in hundreds of thousands of movements that Omega produces each year. The latest iteration of the Omega Speedmaster Moonwatch is kitted out with the co-axial escapement With the merits of the co-axial escapement having been proven in part by its large-scale adoption, my aim here is not to examine its intrinsic qualities, but rather delve into its development. Specifically I will explore the fact that the co-axial escapement might not be an ent...

INTRODUCING: The Jaeger-LeCoultre Polaris Mariner Memovox is an alarmingly different type of Polaris

Although it’s never really taken off as an uber-popular complication like a chronograph or moonphase, the alarm function of JLC’s Memovox watches has, since they were first unveiled in 1968, been exceedingly practical. But it’s a complication that’s usually been found in the watchmaker’s daintier, and perhaps less practical, dress watches. This has meant that … ContinuedThe post INTRODUCING: The Jaeger-LeCoultre Polaris Mariner Memovox is an alarmingly different type of Polaris appeared first on Time+Tide Watches.

You Are There: Visiting The L.A. Mayer Museum For Islamic Art In Jerusalem, Home Of The Breguet No. 160 ‘Marie Antoinette’

When Bhanu Chropra visited Israel on a business trip in 2019, a colleague suggested a short visit to see the historically important sites in Jerusalem, and knowing his passion for horology said that he had a special surprise for him: visiting the L.A. Mayer Museum for Islamic Art. The museum holds one of the world’s most horologically significant pocket watch, clock, and automaton collections, and the star of the show is Breguet No. 160, aka “the Marie Antoinette.”

Introducing: The Aria Manufacture Chronometer From Formex Hodinkee
Formex What We Know Jun 1, 2026

Introducing: The Aria Manufacture Chronometer From Formex

What We Know The last time I covered something from Formex was over a year ago, when the brand released a highly finished, full-ceramic sports watch, complete with a ceramic bracelet and even a ceramic micro-adjust clasp, at an unrivaled price point. Today, the brand continues its upmarket trend with a brand-new watch design called the Aria. The Aria takes the form of a broad, integrated-bracelet design in full grade 5 titanium. The 40mm case feels broader than normal, thanks to an impressively thin case height of 6.9mm, even though the lug-to-lug is still quite reasonable at 45.45mm. While the silhouette gives a smooth look, there's quite a bit of contrasting finishing going on here, with brushing of the titanium case and bracelet links done entirely by hand. Though the styling certainly leans towards its identity as a bold sports watch, there's a lot of subtlety in the design, for example, with the individual bracelet links being slightly curved or the extra dimensionality of the layer of titanium peeking out from each link's milled-out spaces. The clasp includes Formex's proprietary micro-adjust system, which provides extra space on both sides of the bracelet by pulling or pushing each side. There are three dials for the Aria: "Selva Green," "Ardesia Grey," and "Denso Blue." All three have a certain muted look to the hue, matching the slightly darker nature of titanium. Dimensionality is achieved through contrasting indices in rose-gold coloring, set on applied raised p...

Interview: Zenith’s Product Chief Officer on Reviving the Chronometer Cal. 135 SJX Watches
Zenith s Product Chief Officer May 25, 2026

Interview: Zenith’s Product Chief Officer on Reviving the Chronometer Cal. 135

For much of the past quarter-century, Zenith has built its brand on the back of the El Primero — a fast-beating chronograph calibre that debuted in 1969. But last year — for its 160th anniversary — the brand revived the time-only calibre 135 – a legendary competition calibre originally developed in the late 1940s. The reborn movement debuted within a new collection — the GFJ — named after founder Georges Favre-Jacot. To better understand what lies behind the relaunch of the cal. 135, we talked to Romain Marietta, Chief Product Officer at Zenith. David Serra, Technical Director of Movement Development, provided additional production insights. As Mr Marietta explains, the relaunch of the cal. 135 opens a new chapter for Zenith — more exclusive and more artisanal, featuring precious materials, elevated finishing and a classical aesthetic inspired by the designs of the 1950s. In short, closer to the independent watchmakers’ approach and to their audience. And this is only the beginning — the Le Locle-based brand has plans to further develop both the calibre and the collection. The interview was edited for length and clarity. Yannick Nardin (YN): Let’s start at the beginning: what makes cal. 135 so special? Romain Marietta (RM): For context, it was produced from 1949 until 1962. At the time, the pursuit of precision had a real genuine meaning. Watchmakers measured their strength, stature and reputation through the prizes they won. This movement was created f...

Bring a Loupe: An Omega Marine Chronometer, A Zenith 2000, A Marvin Ocean Chief, And A Jaeger-LeCoultre Étrier Hodinkee

Bring a Loupe: An Omega Marine Chronometer, A Zenith 2000, A Marvin Ocean Chief, And A Jaeger-LeCoultre Étrier

Happy Friday, Ballers. The air's getting warmer, the NBA Conference Finals are already providing extraordinarily compelling viewing (even if your team's already been bounced), and you've only got another month and change to set up your 4th of July plans. Don't sweat it, however. To paraphrase Dieter from Sprockets, now is the time on Hodinkee when we look at what's selling where. Scorekeeping last week's picks: the Movado Cronoplan is still available from The Time Curator, the Patek Beta 21 sold for $26,750, the Hamilton auction closes tomorrow, so you've still got time on it if you're interested, and the Zenith Time Command for 460 GBP. Onto the show. Strays I'm certainly not alone in finding vintage Boucheron watches charming and worth more attention, and if you need further convincing, this Reflet makes an awfully compelling case. If you look closely at this Enicar Mantagraph, you'll notice there's no Swiss marking on the dial, and that, though the watch comes in its original Enicar box, the guarantee card is for a Seiko. This would all seem strange and potentially nefarious were it not for the fact that the Enicar Mantagraph is essentially a rebranded Seiko 7016, a movement well worth your time. Speaking of vintage flyback chronographs, here's a Longines 13ZN monopusher with a dial that seems designed by time and circumstance to test where you fall on the 'one man's tropical is another man's damaged' spectrum, and if that one's not enough, here's a Double-Red Rolex Sea...

The Batavi Marine Chronograaf Conjures the Scent of Summer Worn & Wound

The Batavi Marine Chronograaf Conjures the Scent of Summer

As someone who lives within a mile of the Pacific Ocean, the smell of the sea is one of comfort to me. Naturally, this leads me to like candles and fragrances that have a hint of that crisp aquatic breeze. Of course, this has little to do with watches; or at least I thought it did. But Amsterdam-based microbrand Batavi has launched a yacht-inspired fragrance and wristwatch pairing that evokes the ocean in all its aesthetic and olfactory glory, so you can bring that sweet, salty scent with you in more ways than one.  The Marina Chronograaf lineup introduces four variants, each with identical specs but relatively singular designs. To start, each Chronograaf measures in at 46mm lug-to-lug, and a 38mm stainless steel case with 13.5mm of thickness conveys a sporty silhouette. Each model features two subdials, a running seconds and a 30-minute counter at the 9 and 3 o’clock positions respectively, a railroad track around the dial, and hands that lay somewhere between GMT, chronograph, and diver styling. Inside, a hand-wound Seagull ST1901 movement keeps the yacht-timer functionality of each reference ticking and promises a 45-50 hour power reserve. Fifty meters of water resistance, a domed sapphire crystal, see-through caseback, and stainless steel quick-release bracelet round out the package. Four dial options are available, and each colorway is about as distinct from the next as is possible. “Sunrise” features a cotton candy-esque combination of blue and pink, with a gr...

Hands-On: the Buser Fréres Marine 38 Worn & Wound
Nov 21, 2024

Hands-On: the Buser Fréres Marine 38

Whenever a new brand pops up I’m always intrigued. And while I’ve got nothing against a good ol’ dive or field watch, my interest is always piqued if it’s something with a more classic vibe. Especially if there’s some real watchmaking pedigree involved.  Buser Fréres is a newly revived brand originally dating back all the way to 1892. It survived the quartz crisis but initially seized all activities in the year 2000. Twenty-three years later German brand Dekla – who’s been designing and manufacturing watches under their own name for 10 years – revived the brand and launched the first models earlier this year. I’ve been a happy Dekla owner for the last 4 years, so naturally I was thrilled to see the line expanded with the Buser Fréres brand.  While some would rush to categorize Buser Fréres as a micro brand – and nothing wrong with that in particular – I’d just like to point out a couple of facts before we do just that. When I hear the term “micro brand” I tend to associate it with outsourced components brought together into a final product. Once again I’d like to stress: nothing wrong with that. But Buser Fréres offers something of a different recipe as they produce almost everything but the movement themselves.  For 10 years Dekla has been making watch dials, cases and hands in a wide array of materials, sizes and configurations, and that’s what sets Buser Fréres apart from many others in the space – and price bracket. From Grand ...
