Richard Mille Goes Hyper Lightweight with the RM 55-01 SJX Watches
Richard Mille Goes Hyper Lightweight Apr 20, 2026

Richard Mille Goes Hyper Lightweight with the RM 55-01

In an unexpected departure from their its horological extravaganza, Richard Mille has just unveiled the time-only RM 55-01. With a focus on simplified movement architecture and lightness, the RM 55-01’s movement is a hand-wound exercise in restraint and weighs under 5 g – equivalent to one sheet of A4 paper. Initial thoughts At its debut in the early 2000s, Richard Mille basically introduced and then perfected the niche offering of ultra-expensive, “hyper” sports watches, juggling complications, materials and bold aesthetics to create an outrageously expensive cocktail of lightness and ergonomics. With the RM55-01 the same brand returns to the basics, with a caliber developed for extreme lightness, doing away with automatic winding or any complications. The watch only tells the hours, minutes and seconds - which is not really something one expects from Richard Mille these days.  This RM 55-01 feels like a spiritual descendant of the discontinued RM 55 “Bubba Watson”. The case lines and the movement itself are very reminiscent of that model, although the RM 055 was mostly marketed as a light but sturdy golfer’s watch. The new RM55-01 is presented as a pure exercise in weight reduction. Though the price of the RM 55-01 is unavailable, it is probably unjustifiable in any tangible or intrinsic sense. But is a mechanical watch that weighs as much as a few sheets of paper extremely cool? Yes – if you can afford it. Airy construction The RM 55-01 is built with ...

Introducing: The New Chopard L.U.C. Chopard Strike One In Titanium (Live Pics) Hodinkee

Introducing: The New Chopard L.U.C. Chopard Strike One In Titanium (Live Pics)

What We Know Among the more attractive releases from Watches and Wonders this year is the new Chopard L.U.C. Strike One Titanium, now with a beautiful new dial treatment. In ethical 18k rose gold with salmon-colored galvanic treatment, with a hand-guilloché central medallion with a honeycomb motif, the Strike One is a watch that may fly under the radar for some. Not a minute repeater, not a grande et petite sonnerie, but rather a beautiful watch that chimes once at the top of the hour (a sonnerie au passage), it's still got a very romantic quality about it. Despite being a chiming watch, Chopard has (as they usually do) minimized the size as much as possible with a 40mm by 9.86mm case in Grade 5 titanium. That light metal should help emphasize the chime's sound, with the hammer on the dial side visible through an aperture for the full experience. Even better, the gong is made of sapphire and is connected in a monobloc construction (one piece) to the dial crystal to emphasize sound transmission. The dial itself is capped by a snail-shaped chapter ring and has rhodium-plated hour markers and hands, plus anthracite-colored printed transfers. This is all powered by the L.U.C. 96.32-L. With a two-barrel construction and micro-rotor, you get 65 hours of power reserve, automatic winding, and a 4Hz beat rate, all chronometer-certified by COSC, with Poinçon de Genève-certified quality. Chopard really shows bigger brands how to do it when it comes to finishing, so this is the kin...

New Release: Lab Series 1 by Holthinrichs Watches skilfully transports us into a retrofuturistic reality

Today, I present two new models that caught my attention: the automatic Lab Series 1.S, which offers the rare combination of automatic winding and small seconds, and the Lab Series 1.GMT, featuring a straightforward second time zone function with a central 24-hour GMT hand. The post New Release: Lab Series 1 by Holthinrichs Watches skilfully transports us into a retrofuturistic reality appeared first on Quill & Pad.

Introducing – Moritz Grossmann Hamatic Silver-Plated by Friction, For the Founder’s 200th Anniversary

The Hamatic is one of the more unusual watches from Moritz Grossmann, mainly because of how it handles automatic winding. Instead of a central rotor, it uses a hammer-style system, where a pendulum-like weight swings freely in both directions, constantly feeding energy to the movement. It is a more animated way of keeping the watch […]

A Haute Horlogerie Makeover for the Girard-Perregaux Laureato SJX Watches
Girard-Perregaux Laureato Girard-Perregaux GP unveils Nov 19, 2025

A Haute Horlogerie Makeover for the Girard-Perregaux Laureato

Girard-Perregaux (GP) unveils the second chapter of the Laureato’s 50th anniversary with the Laureato Three Gold Bridges Tourbillon. First launched as part of the earlier generation Laureato in the 1990s, the tourbillon has been reimagined with a monochromatic palette in a limited edition of 50 pieces that evokes GP’s golden age as a modern-day manufacture.   Initial thoughts Few tourbillon movements are as iconic as the GP Three Gold Bridges. The concept debuted in a tourbillon pocket watch in 1867 and the manufacture has since adopted the signature arrow-shaped bridge as its logo and even employed the motif in movements without a tourbillon.  Fortunately, the new Laureato is very much a tourbillon; this combination of two icons should please both fans of the brand and enthusiasts alike. The GP9620 tourbillon movement is good example of high-quality, in-house watchmaking, and is evidently constructed and finished to a high standard. Derived from the GP9400 series of movements, the GP9620 features improved finishing and a new monochromatic palette. Remaining true to the original three bridges design, the proprietary calibre retains the visual identity of early GP pocket watch tourbillon movements, including the brand’s iconic tourbillon cage immortalised as its own design by Reinhard Meis in his book Das Tourbillon; very few brands have a tourbillon they can truly call their own. But the movement also incorporates modern amenities like automatic winding – thanks...

Mido Ocean Star: A Complete Guide To The Historic Dive Watch Teddy Baldassarre

Mido Ocean Star: A Complete Guide To The Historic Dive Watch

Mido is not one of the more widely familiar watchmakers in North America - though its watches have enjoyed a longstanding popularity south of the border, in Latin America - despite the fact that the brand, now owned by Swatch Group, has been around for a long time. It was founded on November 11, 1918, the same date of the armistice that ended World War I, by watchmaker Georges G. Schaeren (below) in the Swiss town of Biel-Bienne. Its name comes from the Spanish phrase Yo Mido, meaning “I Measure,” which may or may not indicate that Schaeren had always intended his products to appeal to a large Spanish-speaking audience. What is indisputable is that the Mido brand contributed some significant innovations to watchmaking in the 20th Century, few of which are often acknowledged. The company came up with one of the first solutions to waterproofing watch cases in 1930, developing a sealing system (below) that installed a watertight gasket made of cork between the crown and the case; Mido later named this invention “Aquadura.” The Mido Multifort, still produced today, debuted in 1934 and became the first antimagnetic watch with automatic winding. In 1945, Mido unveiled the Multi-CenterChrono, the first chronograph watch with a central display for the elapsed time, and in 1954 developed the Powerwind automatic winding system that increased efficiency by reducing the number of parts in the mechanism. Of all these milestones, it was the Aquadura waterproofing technolog...

Up Close: Vanguart Orb Tourbillon SJX Watches
Audemars Piguet Renaud & Papi APRP Jul 30, 2025

Up Close: Vanguart Orb Tourbillon

Vanguart is surprisingly under the radar, despite having been eight years old. The brand was founded in 2017 by a quartet that includes alumni of Audemars Piguet Renaud & Papi (APRP), and last year introduced its most notable product yet, the Orb. The watch arguably goes against the grain of independent watchmaking today. Instead of being traditional, simple, and brightly finished, it is appears intricately mechanical and distinctly modern in style. A flying tourbillon wristwatch with an inventive, thoughtful technical approach, the Orb is powered by a layered, skeleton movement with a novel winding-function selector that allows for switching between manual and automatic winding. And it’s been trending recently after having been spotted on the wrist of singer Ed Sheeran during a concert in Germany. Initial thoughts I first encountered Vanguart when it launched the Black Hole Tourbillon in 2021. The brand caught my interest because it was set up by an all-star team that included two technical experts from APRP. Though the Black Hole was technically impressive, the oversized, space-ship shape felt overdone and way too much on the wrist (and also twice as expensive). The Orb, on the other hand, is (almost) just right. When I first saw the Orb, I thought it might be yet another basic tourbillon movement in fancy dress but priced exorbitantly. I was wrong. The movement is impressive in many respects. The Black Hole Tourbillon. Image – Vanguart The Orb is both minimalist and...

Record Breaking Konstantin Chaykin ThinKing Debuts at Auction SJX Watches
Patek Philippe Calibre 89 ref 989J May 2, 2025

Record Breaking Konstantin Chaykin ThinKing Debuts at Auction

If you want to own the world’s thinnest mechanical watch, the Konstantin Chaykin ThinKing, you’ll have to fight for it at The Geneva Watch Auction: XXI, which will see the first production example go under the hammer. The 1.65 mm stature of the ThinKing is even more impressive coming from a small Russian independent watchmaker, considering previous records were set by big Swiss brands ranging from Piaget to Richard Mille. Notably, this is not the first time a landmark release has been trusted to an auction that isn’t linked to a charity. The most famous example of this was the Patek Philippe Calibre 89 (ref. 989J) back in 1989 at Antiquorum’s thematic sale. The ThinKing will be sold in the first session of the auction, which starts on May 10, 2025, at 2 pm. The ThinKing in profile. Image – Phillips Mr Chaykin achieved the record-setting height with clever construction, including a “double balance wheel” system that places an intermediate wheel between the balance and escapement, allowing both to sit on the same plane. Another notable technical feature is a barrel that is open on both sides, and no thicker than the mainspring itself. And unlike most serially-produced Konstantin Chaykin watches, each ThinKing is made, finished, and assembled by Mr Chaykin himself. Wearability is enhanced by the bolt-on protective shroud in titanium christened “PalanKing”. This increases the height to 5.4 mm, but adds key-less setting and winding, and automatic winding by a...

Fears Unveils a Very Limited Version of the Brunswick Jump Hour for British Watchmakers’ Day Worn & Wound
Christopher Ward Jan 10, 2025

Fears Unveils a Very Limited Version of the Brunswick Jump Hour for British Watchmakers’ Day

With the release of their Brunswick 40.5 Jump Hour watch in 2024, Fears built on the already elegant jump hour platform that debuted with their Alliance 01, built in collaboration with Christopher Ward in 2023. Continuing this form, the Bristol-based company has announced the Brunswick 40.5 Jump Hour ‘Edwardian Edition’ to celebrate British Watchmaker’s Day 2025. Limited to 10 pieces and available exclusively at the British Watchmaker’s Day event on Saturday, March 8th, the Edwardian Edition features much of the same elegance as its predecessors, albeit with a few special details. The full-polished sterling silver case-Fears’ second such case in 100 years-wears a London Assay Hallmark, Fears’ own maker’s mark, and a flawless diamond-set crown, while the strap sports a matching sterling silver buckle. Like the original Brunswick Jump Hour, the Edwardian Edition is powered by the Christopher Ward JJ01 jumping hour module, which features automatic winding and a 38-hour power reserve.  What sets the Edwardian Edition apart, though, is the stunning, hand-polished white lacquer dial, which features numerals and a Fears’ logo derived from the brand’s Edwardian-era pocket watches; a hand-varnished and diamond-cut glossy black minute hand pops against the multi-layer lacquer. In addition to the dial, an exclusive heritage-inspired hour disc and a maple red Alcantara strap (lined with English Tan calf leather) further elevate the Edwardian Edition. Each watch ...

TAG Heuer Remembers Ayrton Senna with Carrera Chronograph Tourbillon SJX Watches
TAG Heuer Remembers Ayrton Senna Oct 31, 2024

TAG Heuer Remembers Ayrton Senna with Carrera Chronograph Tourbillon

Legendary Formula 1 champion Ayrton Senna was a longtime TAG Heuer ambassador up until his death in 1994. On the 30th anniversary of his passing, the Brazilian driver is coming back to the fore with TAG Heuer unveiling the Carrera Chronograph Tourbillon x Senna just in time for the premiere of the Netflix series Senna. Based on the Carrera Chronograph Extreme Sport, the Senna edition is presented in titanium, carbon composite, and the colours of the Brazilian flag. It bears the driver’s emblem on the carbon composite and hour register at nine, while the case back depicts a helmeted Senna. Senna himself frequently wore the TAG Heuer S/el ref. S25.706C multi-function, which will also be seen in the upcoming television series Initial thoughts TAG Heuer is in some ways an underdog – because of its many affordable offerings, its higher-end models sometimes don’t get enough attention. The Carrera Dato “Glassbox”, for instance, is a vintage-inspired but original design that’s appealing and powered by an in-house movement. The Carrera Chronograph Tourbillon is an integrated chronograph with automatic winding, plus a flying tourbillon, albeit an industrial movement. The big and bold styling isn’t the retro-inspired design that Heuer enthusiasts appreciate, but the Senna edition is executed well and priced right. Personally speaking, the Senna edition is not my style - there are too Senna elements in the design, unlike the low-key regular-production version. However...

Grand Seiko Introduces the SLGW002 and SLGW003 “Birch Bark” SJX Watches
Grand Seiko Introduces Apr 12, 2024

Grand Seiko Introduces the SLGW002 and SLGW003 “Birch Bark”

Grand Seiko has introduced the Evolution 9 “Birch Bark” SLGW002 and SLGW003, in rose gold and “brilliant hard titanium” respectively. Named after the dial pattern, the “Birch Bark” is powered by a new manually-wound, high-beat caliber that features the brand’s proprietary dual-impulse escapement. The only completely new model introduced by Grand Seiko at Watches & Wonder this year, the new references introduce a new, notably slimmer aesthetic to the brand’s Evolution 9 collection.  Initial thoughts Grand Seiko has earned a devoted following in recent years, but collectors have been asking for slimmer options for some time; this release proves the brand is listening. While there’s nothing revolutionary about it, the watch has been nipped and tucked in all the right areas, getting the case down to 38.6 mm in diameter and just under 10 mm in thickness.  Compared to the most similar existing watch in the catalog, the Spring Drive SLGA009 “White Birch” launched two years ago, the new Evolution 9 feature a new movement, a thinner case, slimmer dial markers, and a horizontal interpretation of the brand’s signature white birch-inspired dial texture. The slimmer profile is made possible thanks to the new 9SA4 movement, which is essentially a 9SA5 without automatic winding. This makes it the first manually wound caliber from Grand Seiko’s latest generation of mechanical movements, and also the first to be available without a date function. Perhaps the onl...

Seiko Presage Cocktail Time Guide Teddy Baldassarre

Seiko Presage Cocktail Time Guide

In their relatively short tenure on the international market, Seiko’s Presage “Cocktail Time” watches have already established themselves in the minds of many enthusiasts as one of the watch industry’s very best value prospects in the realm of automatic dress watches - boasting in-house movements, high-end finishing, and the colorful dials that lend them their nicknames, each inspired by concoctions from Japan’s world-famous high-end cocktail bars. Here is a guide to the Seiko “Cocktail Time,” with highlights and milestones from the modern collection. Happy Hour in Japan Seiko served up the first round of its “Cocktail Time” watches exclusively to customers in Japan. The first of these  “JDM” (Japan Domestic Market) models debuted in 2010 and carried the Reference number SARB065. Now discontinued (and accordingly in high demand by collectors), this watch (above) and its siblings, the SARB066 and SARB068, featured 40mm cases in stainless steel, which were fairly thick at 13.3mm high. The movement inside the cases was Seiko’s Caliber 6R15, with bidirectional automatic winding, a 50-hour power reserve, and an impressive resistance to magnetic fields of 4,800 A/m.  Unlike the many Presage models that followed, the originals were not nicknamed after specific cocktail concoctions but simply for different styles: the SARB065 with its ice-blue dial was “Cool,” the SARB066 with a pale, cream-colored dial was “Dry,” and the reddish brown dial of t...

Up Close: Piaget Polo 79 SJX Watches
Vacheron Constantin 222 Feb 13, 2024

Up Close: Piaget Polo 79

In an unsurprising move given recent fads, Piaget just announced the Polo 79, a yellow gold wristwatch that is essentially a remake of the original, with a slightly larger case that captures the proportions of the original and an impressively slim movement. Initial thoughts The Polo 79 is a predictable launch, coming shortly after the Vacheron Constantin 222 and IWC Ingenieur, which are of course products of Piaget’s sister companies. The new Polo sticks to the same formula, gently updating the aesthetics and installing a new movement, but largely preserving the same design. So the Polo 79 can’t be commended for creativity, but it is executed well. That said, creating a new design in the spirit of the original – namely geometric forms, slim, and sporty – would have certainly made it a more interesting watch. The Polo 79 is slightly larger than the original, but substantially thicker thanks to a self-winding movement. The original, on the other hand, was equipped with the quartz cal. 7P, an incredibly thin movement that fit the trends of the time. The increase in size means the new Polo feels like a bulked up version of the original, which was small and flat in keeping with 1980s style. To accommodate modern tastes, the Polo 79 sacrifices the thinness of the original. That is regrettable but forgivable, since it would not be possible to achieve sufficient water resistance (the Polo 79 is rated to 50 m) as well as automatic winding in the dimensions of the original c...

In-Depth: The Grand Seiko Tentagraph SLGC001 SJX Watches
Grand Seiko Tentagraph SLGC001 Twenty twenty-one Jan 15, 2024

In-Depth: The Grand Seiko Tentagraph SLGC001

Twenty twenty-one was an important year for Grand Seiko as it saw the introduction of the brand’s latest-generation mechanical movement, the cal. 9SA5. A modern movement with attractive aesthetic and proprietary escapement, the cal. 9SA5 debuted in the Heritage “White Birch” SLGH005. But Grand Seiko didn’t stop there. Building upon the flagship calibre, Grand Seiko created the cal. 9SC5 and launched the Grand Seiko Tentagraph SLGC001. A large, sporty watch but entirely in lightweight titanium, the Tentagraph is a milestone for Grand Seiko (GS) as the brand’s first-ever mechanical chronograph. “Tentagraph” is self-explanatory, an acronym outlining the key features of the watch and cal. 9SC5 within: TEN beats per second, Three-day power reserve, Automatic winding, and chronoGRAPH. Initial thoughts The Tentagraph has all the tactile features expected in a modern, high-spec sports chronograph, namely substantial proportions and crisp, smooth pusher action. As expected for GS, it boasts high quality finishing inside and out, with the case in particular having category-leading finishing and detailing. And from a technical perspective, it is notable for being the high-frequency chronograph with the longest power reserve on the market – the balance runs at 36,000 beats per hour, or 5 Hz, and the power reserve is 72 hours, or three days. Aesthetically, the Tentagraph is refreshingly modern. It retains the characteristic GS design, but tweaked to accentuate the sport...

Best of 2023: Complications SJX Watches
Audemars Piguet Universelle but Dec 26, 2023

Best of 2023: Complications

Twenty twenty-three was a year where familiar complications were reimagined. The year’s standouts in terms of complications are characterised by good execution. Granted, most of of them are evolutionary, except perhaps for the Audemars Piguet Universelle, but a classic complication done well is arguably superior to a novel idea done badly. We asked our team members well versed with the year’s complications for their favourites and here they are. SJX The year’s most complicated and most impressive (multi) complication came from a surprising brand, Audemars Piguet. Even though it was the Royal Oak Travis Scott and Royal Oak Concept “Spider-Man” that captured the headlines, the Code 11:59 Universelle was questionably AP’s most important watch of the year from a watchmaking perspective. The Universelle manages to pack almost two dozen complications, including a grande sonnerie, perpetual calendar, split-seconds chronograph, and notably, automatic winding, into a case that’s just 42 mm wide and 15.55 mm high – a positively slender case by the standards of grand complications. By comparison, the F.P. Journe Astronomic is 44 mm by 13.7 mm, while the Patek Philippe Grandmaster Chime measures 47.7 mm by 16.07 mm. AP managed to do that with sophisticated and ingenious engineering, most notably by integrating the split-seconds mechanism into the automatic winding hub. The clever technical solutions are also evident in the calendar, which has an extra-thin construction...

The Many Handwinding Flavors of Hamilton Worn & Wound
Hamilton There’s something special about Oct 8, 2023

The Many Handwinding Flavors of Hamilton

There’s something special about hand winding a watch. Sure, automatics are great, but the great thing about them is that they don’t really need you to keep doing their job. The most interaction you’d have with the crown on your automatic is maybe setting it should the power reserve run out over a long weekend. Handwinding watches require a bit more work, but that few minutes of winding in the morning before your day begins is a great opportunity to interact with your favorite watch. Romanticism aside, there are some key physical benefits as well. Most importantly being that since there’s no automatic winding rotor section needed for the movement, handwinding movements tend to be thinner and able to be housed in smaller cases that may wear better on your wrist. One iconic brand that’s still actively embracing handwinding watches is Hamilton. With the huge success of their Khaki Field Mechanical, it’s clear that enthusiasts still want handwinding watches, especially when they’re as solidly built, packed with features, and as functional as the Hamiltons below. Let’s take a look at three handwinding Hamiltons in the Windup Watch Shop and what makes them special. There’s something special about hand winding a watch. Sure, automatics are great, but the great thing about them is that they don’t really need you to keep doing their job.

Grand Seiko Introduces the Tentagraph SLGC001 SJX Watches
Grand Seiko Introduces Mar 27, 2023

Grand Seiko Introduces the Tentagraph SLGC001

Grand Seiko made a big splash at last year’s Watches & Wonders with the launch of the Kodo Constant-Force Tourbillon, the brand’s first complicated mechanical wristwatch. For 2023, the brand is back with another first-time complication that will likely be one of the most talked-about watches of the show, the Grand Seiko Tentagraph SLGC001. The first purely mechanical Grand Seiko chronograph ever, the Tentagraph is a high-spec sports chronograph that fills a hole in the Grand Seiko portfolio. “Tentagraph” is a portmanteau of the four key features of the watch: TEN beats per second, Three-day power reserve, Automatic winding, and of course, the chronoGRAPH. Initial thoughts The Tentagraph is an important watch for Grand Seiko that enables the brand to stand toe to toe with Rolex, Omega, Zenith, Breitling, and other stalwarts in the popular category of mechanical sports chronograph. Not only is the category a hitherto untapped commercial opportunity for Grand Seiko, it is an opportunity for the brand to demonstrate its technical know-how and ambition. In this context, I would have expected the brand to release an integrated chronograph movement, perhaps based on the 6S movement family. But Grand Seiko has chosen to build a modular chronograph calibre based on the 9SA5, the flagship Grand Seiko automatic movement introduced in 2020, signalling the brand’s commitment to the calibre and its proprietary Dual Impulse Escapement. My colleague Richard Lee notes that the 9S...

Audemars Piguet Introduces the Royal Oak Concept Split-Seconds Chronograph GMT SJX Watches
Audemars Piguet Introduces Feb 3, 2023

Audemars Piguet Introduces the Royal Oak Concept Split-Seconds Chronograph GMT

Amongst the wave of new Royal Oaks just unveiled by Audemars Piguet (AP) is a new “Concept”, the Royal Oak Concept Split-Seconds Chronograph GMT. Historically a platform to showcase novel materials and aggressive design, the new Royal Oak Concept (ROC) continues down that route – but more notably contains an all-new and cleverly-constructed rattrapante chronograph movement with automatic winding. Initial thoughts Much like previous models in the ROC line, the new split-seconds chronograph is a bold statement with a chunky, aggressive case, albeit one refined to become more wearable, especially in light of its size – it is the most wearing Concept to date. Paradoxically, the movement within the large-format case was clearly designed with thinness in mind. For a split-seconds chronograph with a big date, second time zone, and automatic winding, the movement measures a modest 8.92 mm high, svelte by the standards of the complications mix. And in contrast to the design (which brings to mind the Richard Mille RM 11), the movement is unusually refined and clever. An example of is the rotor that’s supported by a large central hub, which provides enough space in the middle to house the entire split-seconds mechanism. This serves to both reduce thickness, while simultaneously offering a view of the rattrapante mechanism without being obstructed by the rotor. Deceptively oversized As with most of its counterparts in the collection, the new ROC has a geometrically-shape...

Longines Ultra-Chron: The World's First High-Frequency Dive Watch Retu Teddy Baldassarre
Longines Feb 1, 2023

Longines Ultra-Chron: The World's First High-Frequency Dive Watch Retu

The Longines Ultra-Chron takes its most direct inspiration from a dive watch the brand introduced in 1968, but it also represents the culmination of Longines’ expertise in making high-frequency watch movements, which goes back more than 100 years. Longines’ century-plus quest for high-frequency timekeeping precision started in 1914, when it produced the first hand-held stopwatches (like the one below) with movements that measured time to 1/10 second thanks to their high-frequency movement, Caliber 19.73N, whose balance wheel oscillated at 36,600 vph. It continued with a modification of that caliber to achieve an astonishing rate of 360,000 vph, and a stopwatch accuracy of 1/100 second, in 1916; hit a new milestone with the launch of the Observatory Chronometer in 1959, the first wristwatch with a 36,600-vph movement; and culminated with the introduction of the Ultra-Chron Diver (below) in 1968, which became the world’s first high-frequency divers’ watch, housing the 36,600-vph Caliber 431. (Yes, this predates by one year the most famous high-frequency movement, the Zenith El Primero, though that movement also incorporated automatic winding and a chronograph.) The Ultra-Chron Diver provides the template for the all-new Ultra-Chron model, whose cushion-shaped stainless steel case spans a contemporary 43mm in diameter and 13.6mm thick as well as a 300-meter water resistance - an improvement on the vintage model’s 200-meter rating. Like its predecessor, and in th...

Laurent Ferrier Introduces the Square Micro-Rotor SHH Edition SJX Watches
Greubel Forsey Double Balancier Convexe Oct 31, 2022

Laurent Ferrier Introduces the Square Micro-Rotor SHH Edition

Having recently reopened Sincere Haute Horlogerie (SHH), a “concept” store dedicated to independent brands, Singapore retailer Sincere commissioned limited editions from several watchmakers to mark the event, including the Greubel Forsey Double Balancier Convexe in purple. Following that, SHH has unveiled another finely decorated time-only wristwatch, the Laurent Ferrier Square Micro-Rotor SHH Edition. With Breguet numerals on the front and a natural escapement on the back, the SHH Edition is classical but given a contemporary aesthetic with a gradient mint green. Initial thoughts A store with 19 brands on its premises, SHH certainly has a diversity of watchmaking on offer. But amongst its most technically accomplished time-only watches are the creation of Laurent Ferrier. Seemingly plain-vanilla on the front, the brand’s Micro-Rotor is tells a different story on the reverse. The movement revives Abraham-Louis Breguet’s escapement from two centuries ago, while the automatic winding mechanism is elaborately executed. It is a watch that is easily appreciated by collectors who appreciate history and chronometry. Like most collaborative editions, the SHH edition retains the flavour of the original, but with enough tweaks that it appeals to the target audience, namely watch enthusiasts who like classical design. While many of the dial details are familiar, they are combined in a coherent and restrained manner. The effect is subtle but significant. When I first encounte...
