Up Close: Harry Winston Opus 1 Tourbillon by F.P. Journe SJX Watches
F.P. Journe Jun 3, 2021

Up Close: Harry Winston Opus 1 Tourbillon by F.P. Journe

A variant of the fourth-generation F.P. Journe Tourbillon Remontoir d’Egalite, the Opus 1 Tourbillon was part of the inaugural project of the Opus series, the annual independent-watchmaker collaboration invented by Max Büsser of MB&F; fame. Named after the Opus One vineyard that’s also a joint venture between Americans and Europeans, Opus established Harry Winston as a bona fide watchmaker. Though Harry Winston has now put more emphasis on its primary jewellery business, its past Opus projects are mostly interesting and important examples of contemporary watchmaking. Ironically, despite being the opening act, the Opus 1 models were amongst the least novel, because they were essentially F.P. Journe movements dressed in Harry Winston attire. But that also makes the Opus 1 interesting simply because they were F.P. Journe. The Opus 1 was made up of three models – the Tourbillon, Resonance, and Reserve de Marche – each based on the equivalent F.P. Journe model, meaning an identical movement but a platinum case in the trademark Harry Winston style. Phillip’s Hong Kong watch auction this weekend includes an Opus 1 Tourbillon, which is worth a closer look, if for no other reason than the fact that it’s one of the rarest variants of the early F.P. Journe tourbillon. Initial thoughts The Opus 1 – any one of the three versions – is a peculiar watch. It is fundamentally an F.P. Journe, yet feels nothing like an F.P. Journe. If you closed your eyes and compared the two...

INTRODUCING: The new Oris Hölstein Edition is a cool grey vision of a Big Crown future

The Oristas out there eagerly anticipate the annual Oris Hölstein Edition, and the Big Crown is a beloved staple of the range.

Breitling Introduces the Super Chronomat SJX Watches
Breitling Introduces May 6, 2021

Breitling Introduces the Super Chronomat

Breitling revived the classic 1984 version of the Chronomat just last year, right down to the signature Rouleaux bracelet. Now the brand ups the ante with the introduction of the Super Chronomat, a larger, 44 mm watch that’s available in two guises: the B01 chronograph and more interestingly, a chronograph combined with the “1461” four-year calendar that was once a signature complication for Breitling. Initial thoughts At a time where brands are downsizing their best known designs, the Super Chronomat bucks the trend. Bigger and bolder than its smaller sibling, the Chronomat “is a watch you’ll get noticed in without having to worry about it” says Breitling chief executive Georges Kern in the launch announcement. I’m inclined to agree – the new Super Chronomat definitely makes a statement. With the distinctive Rouleaux bracelet and oversized pushers, the Super Chronomat possesses a temerity in design that is reminiscent of Breitling in the mid 2000s when the brand favoured excessive sizing, but packaged in a modern manner. That said, the new Super Chronomat collection has a cool 1980s vibe as well, particularly with the UTC module that’s an option on the Super Chronomat B01. The black dial Super Chronomat B01 44, with a UTC module in the bracelet Then there’s the Super Chronomat 44 Four-Year Calendar, which features a semi-perpetual calendar. Formerly the flagship complication for Breitling, the calendar is known as the 1461 after the number of days in...

Jaeger-LeCoultre Introduces the Reverso Hybris Mechanica Calibre 185 Quadriptyque SJX Watches
Jaeger-LeCoultre Introduces Apr 27, 2021

Jaeger-LeCoultre Introduces the Reverso Hybris Mechanica Calibre 185 Quadriptyque

Appropriately for the 90th anniversary of famed reversible wristwatch, Jaeger-LeCoultre (JLC) has debuted the ultimate Reverso. Boasting 11 complications, including a tourbillon, minute repeater, and instantaneous perpetual calendar, the Reverso Hybris Mechanica Calibre 185 Quadriptyque is a monumental wristwatch with four faces and a movement made up of 800 parts. Initial thoughts The Calibre 185 Quadriptyque is smaller than the Reverso Grande Complication à Triptyque – which was so big as to be almost unwearable for most – but still sizeable enough to be clunky. It measures 51.2 mm by 31 mm, while standing 15.15 mm high, making it larger than the biggish Nonantième that was launched at the same time. Granted, the size is necessary for the ultra-complex, four-faced movement. Majority of the complications within the new grand complication can be found in past JLC watches, making the Calibre 185 Quadriptyque something of a greatest-hits compilation for the brand. Impressive as it is, the Calibre 185 feels dated, in the sense that watches with numerous complications stacked up were a “thing” in the 2000s; the Triptyque was launched in 2007 and truly exotic in its day. Now that such watches are fairly common, with many leading brands having their own grand multi-complications, the concept is less impressive, regardless of the technical achievement. It’s also worth pointing out that the watch is elaborately decorated – mainly with Clous de Paris guilloche ...

TAG Heuer Introduces the Monaco Green Dial SJX Watches
TAG Heuer Introduces Apr 24, 2021

TAG Heuer Introduces the Monaco Green Dial

Organised by the Automobile Club de Monaco (ACM), the Grand Prix de Monaco Historique is an annual classic-car race that traditionally takes place before the city’s Formula 1 Grand Prix. As the official timekeeper of the event, TAG Heuer is marking this year’s race with the Monaco Green Dial. A facelifted variant of its iconic square chronograph, the new Monaco features a gradient-green dial that’s a first for the Monaco, but an exceptionally common colour this year. Initial thoughts Arguably the iconic Heuer chronograph by virtue of its unmistakeable 1970s style, the Monaco was introduced in 1969 in honour of the Monaco Grand Prix. An unusual combination of a water-resistant, automatic chronograph with a square case, the Monaco remains the brand’s most recognisable timepiece. While the choice of a green dial may feel modish – dials in this shade seem endless this year even though it’s only April – it is nevertheless well executed. The smoked, metallic finish lends the watch a more nuanced look that separates it from most watches with a green dial. It might not be novel, but I’ve seen the new Monaco in the metal and it is one of the more attractive green dials that I’ve seen to date. While the remake of the original Monaco ref. 1133 “Steve McQueen” would be my pick from the Monaco lineup – I appreciate its historically-faithful design – the new Monaco in green is a great option for someone seeking a more contemporary watch that still possesse...

Patek Philippe Introduces the Calatrava “Clous de Paris” Ref. 6119 SJX Watches
Patek Philippe Introduces Apr 13, 2021

Patek Philippe Introduces the Calatrava “Clous de Paris” Ref. 6119

Though now often overlooked in favour of a luxury-sports watch, the Calatrava is perhaps the quintessential Patek Philippe – it was introduced in 1932 and named after the brand’s emblem – possessing a diversity of designs that all share an elegant simplicity. Patek Philippe’s second instalment of new watches at Watches & Wonders 2021 focus on fine, sophisticated wristwatches – it also just announced a striking new perpetual calendar – and naturally encompasses the Calatrava, which sees the addition of the Calatrava “Clous de Paris” ref. 6119. A tribute to well-known Calatrava models such as the ref. 3919 and its successor, the ref. 5119, the ref. 6119 blends several signature elements of past designs in a larger case to create a more contemporary guise that’s available in rose or white gold. Importantly, the ref. 6119 is powered by the newly-developed, hand-wind cal. 30-255 PS, a large, thin movement with twin barrels – and an impressively high moment of inertia for the balance wheel. The cal. 30-255 PS Initial thoughts I’ve always been a fan of the Calatrava, especially variants with a hinged, “hunter” back like the ref. 5227. Best described as fine watches for gentlemen, they typify Patek Philippe’s traditional and refined approach to watchmaking. But the cases of previous generations of the Calatrava were relatively small – the ref. 3919 was 33 mm, while the ref. 5119 had a 36 mm case. And more recent models, like the 40 mm ref. 6007 int...

Breitling Introduces the Premier Heritage Chronograph and Datora SJX Watches
Breitling Introduces Apr 6, 2021

Breitling Introduces the Premier Heritage Chronograph and Datora

Breitling’s opening salvo for the year is a trio of chronographs at Watches & Wonders 2021. The first is the Premier Heritage Chronograph, a straightforward, two-register chronograph, and another is the Premier Heritage Datora, an old-school combination of a chronograph with triple calendar. (The flagship model is the Premier Heritage Duograph split-seconds chronograph, which we cover in another story.) The new Premier Heritage collection is modelled on its namesake line from the 1940s, continuing the brand’s recent efforts of revisiting its past catalogue and re-introducing notable references, but with a couple of modern twists, like the mint-green dial for the Premier chronograph. The Premier Heritage Chronograph in steel Initial thoughts I’m a big fan of the new releases. While the Premier Heritage Chronograph may not be the most innovative, it’s an improvement over the previous generation Premier chronograph. For one, the case size has been reduced to 40 mm from 42 mm, giving the new watch proportions more akin to its vintage inspiration. The dial, now sans date window, is cleaner too. And its manual-winding movement should please traditionalists, who can also admire the movement through a sapphire case back without a rotor to obscure the view. That being said, the mint-green dial will likely divide opinions. It’s a bold look, but I can’t help but wonder if keeping to a safer colour would have been the wiser choice given the retro design. The Datora in ...

Frederique Constant Unveils 40 Hz Silicon Oscillator SJX Watches
Frederique Constant Unveils 40 Hz Silicon Mar 27, 2021

Frederique Constant Unveils 40 Hz Silicon Oscillator

Best known for affordable complications, Frederique Constant’s recent watches include a flyback chronograph for US$4,000 and a perpetual calendar for a bit under US$10,000. But the brand has also applied modern technology to its watchmaking with its analog smartwatches. The brand’s latest offering is cutting-edge horology, but in a mechanical movement. The Slimline Monolithic Manufacture is equipped with an automatic movement that runs at 40 Hz, or 288,000 beats per hour (bph), thanks to a compliant-mechanism silicon oscillator instead of a balance wheel. Initial thoughts It’s a pleasant surprise to see Frederique Constant delving into advanced horological solutions with its silicon compliant mechanism and entering a space often associated with pricier brands like Ulysse Nardin and Zenith. Even more impressive is the fact that the movement is not just as a concept, but a commercially available watch that will be in stores in fall of this year and priced relatively affordably, starting at €4,495, or about US$5,300, in steel. The advanced movement leaves the design of the Monolithic Manufacture incongruous with its classical styling and a truly modern oscillator. However, as such watches go, the design is not the point – it is all about the novel escapement that will certainly pique the interest of technical-minded enthusiasts. Hi-tech collab The high-frequency silicon oscillator was born of a collaboration with Flexous, a startup focused on compliant mechanis...

Konstantin Chaykin Introduces the “Wristmon” Santa 2021 Special Edition SJX Watches
Konstantin Chaykin Dec 16, 2020

Konstantin Chaykin Introduces the “Wristmon” Santa 2021 Special Edition

Now an annual tradition for Russian watchmaker Konstantin Chaykin – and also his bestseller by a wide margin – the googly-eyed and whimsical Wristmon watch has been dressed up for this year’s holiday season. A limited edition of just three watches, the Santa 2021 Special Edition incorporates Yuletide motifs into the design, which retains the signature regulator-style, “moving eye” display, but with a surprisingly complex modification of the construction made necessary by Santa’s spectacles. Initial thoughts Though Konstantin Chaykin’s technical achievements are many – including a watch that can tell time on Mars – his most famous creation is the Joker of 2017, which spawned the Wristmon collection. Simple but amusing, the Wristmon watches are impossible not to like. Mr Chaykin has introduced many variants of the Wristmon, but mostly in extremely small runs, allowing them to remain fairly uncommon. The Santa edition, for instance, is a limited edition of just three. But despite the small run, Mr Chaykin has thoroughly revamped the watch to accommodate the new face, which reflects his attention to even the smallest of details – a quality exemplified by the one-off Joker Selfie. The Santa face on the dial is actually wearing a pair of glasses – made up of a frame with two individual sapphire lenses – which called for modification to both the dial as well as time display module. Though it’s priced substantially higher than earlier versions of the Wr...

Audemars Piguet Introduces the Code 11.59 Selfwinding Flying Tourbillon SJX Watches
Audemars Piguet Introduces Dec 9, 2020

Audemars Piguet Introduces the Code 11.59 Selfwinding Flying Tourbillon

Launched with a solid-colour, grand feu enamel dial, the Code 11.59 Selfwinding Flying Tourbillon has been given simple but significant facelift with a new dial that’s a mix of aventurine glass and vitreous enamel. Made up of ground, powdered aventurine glass mixed with enamel powder, the dial has a deep, glossy surface with the characteristic sparkly metallic inclusions of aventurine glass. Initial thoughts When Audemars Piguet first launched the Code 11.59, only the perpetual calendar model had an aventurine-glass dial, and it was one of the best looking watches in the line up. Though not exactly identical, the aventurine-glass dials on the new tourbillons are no doubt as appealing, especially since they fill up the expanse of the dial. Even though the Code 11.59 lacks the desirability of the fashionable Royal Oak, it is an appealing watch when done right, as this one is. The new dial is a good fit for the case, which was well done to begin with. Featuring a fairly complex construction for a round watch, the case is sharply finished. Arguably the only downside of the case is its size, which is not large at 41 mm wide, but feels chunky on the wrist. The cal. 2950 made its debut last year with the Code 11.59. Also found in the recently launched Royal Oak tourbillon, the cal. 2950 is an attractively designed movement with an unusual detail: a grande sonnerie-style winding click integrated onto the barrel ratchet wheel. With a retail price of about US$150,000, the Code 11...

Hermès Introduces the Slim d’Hermès Quantième Perpétuel in Titanium SJX Watches
Hermes font was created Nov 12, 2020

Hermès Introduces the Slim d’Hermès Quantième Perpétuel in Titanium

Originally introduced in pricier precious metals – in gold and also platinum – the Slim d’Hermès Quantième Perpétuel has been given a makeover that renders it more affordable, and arguably more striking. And like last year’s time-only Slim d’Hermès, the key feature is a titanium case. The new perpetual calendar features a twin-metal case made up of a titanium middle along with the bezel, crown, and pushers in either rose gold or platinum. That, combined with the two-tone grey dial, gives it a modern look that goes well with the Slim d’Hermès font that was designed specifically for the model. The Slim d’Hermes font was created by graphic designer Philippe Apeloig to go with the eponymous watch Initial thoughts Hermes’ house style is always elegant, often quirky, and usually distinctive. Already the Slim d’Hermes design is slim and wears well, and probably slightly better in this iteration since the use of titanium would reduce reduce its weight. A simple design characterised by clean lines, the Slim d’Hermes is recognisable in all its iterations thanks to its smart details, like the angled lugs and custom typography. Though the layout of the perpetual calendar is fairly conventional – everything is arranged into four sub-dials – it manages to be slightly unusual thanks to the seemingly random armament of numerals for the second time zone at six, a minor, offbeat detail that is in keeping with the brand’s style. The titanium-and-platinum versi...

MB&F; Introduces the LM Perpetual EVO SJX Watches
MB&F; Oct 13, 2020

MB&F; Introduces the LM Perpetual EVO

The most complicated MB&F; watch when it was launched in 2015, the LM Perpetual (or LM QP) was powered by an ingenious movement combining a “split” escapement and a novel perpetual calendar mechanism developed by Irish watchmaker Stephen McDonnell. Now MB&F; has reworked the watch to create its sportier and more robust successor, the LM Perpetual EVO. Featuring several tweaks to the case, dial, and movement that are cumulatively significant, the LM Perpetual EVO boasts increased water resistance along with an integrated rubber strap. The LM Perpetual EVO is a limited edition of 15 watches each in black, blue, and orange Initial thoughts Even though the Legacy Machine (LM) line was conceived as something inspired by the 19th century and Jules Verne, the LM Perpetual with its open-worked, intricate dial was always stylishly modern, though that was toned down by the white-lacquered sub-dials of the original model. The EVO, however, makes full use of the open-worked dial to become an uber-contemporary watch. Both the material and construction of the case are new: it’s now zirconium with a more complicated architecture, featuring recessed sides and angular lugs that integrate with the strap. And the sub-dials are black, creating a striking contrast against the base plate in black, blue, or orange. Most notably, the EVO brings to mind the Harry Winston Project Z1, which was the other major product developed by MB&F; founder Maximilian Büsser when he was chief executive of ...

Vacheron Constantin Introduces the Overseas Self-Winding in Pink Gold and Blue SJX Watches
Vacheron Constantin Introduces Sep 9, 2020

Vacheron Constantin Introduces the Overseas Self-Winding in Pink Gold and Blue

Relaunched in 2016 after a major revamp, Vacheron Constantin’s Overseas luxury-sports watch has since been expanded to include various complications, most notably the recent ultra-thin, skeleton perpetual calendar. The mix of a pink gold case and blue dial has been used extensive throughout the line, primarily on complicated models, but the fashionable combination has now been applied to the base model with the Overseas Self-winding in Pink Gold and Blue. Initial thoughts Blue dials have become the archetype for the luxury-sports watch, so the new watch is sticking to a well-established formula. The dial on the new Overseas is quite captivating, largely owing to the use of a brighter blue than usual. Also familiar is the combination of a blue dial and pink gold case, which creates a rich yet sporty look. The combination would be arguably be more appealing if it were applied to the ultra-thin model, which was once in the catalogue but is temporarily discontinued. Priced at a little over US$46,000, the Overseas in pink gold is a contestant in a highly competitive arena, with the primary rivals being the similarly-priced – but far more difficult to obtain – Nautilus and Royal Oak. The two rivals have a slightly longer history, but all of the watches offer similar value in terms of intrinsic quality; the Overseas is very good at what it does. Refined and modern The Overseas Self-Winding has all of the details that characterise the 2016 redesign that resulted in a cleane...

Highlights: Independents and the Esoteric at Phillips’ Hong Kong Auction SJX Watches
Girard-Perregaux Sea Hawk II Pro Jul 7, 2020

Highlights: Independents and the Esoteric at Phillips’ Hong Kong Auction

Taking place on July 10, The Hong Kong Watch Auction: X is the one of the first watch auctions in Hong Kong in 2020, a sign of the much-delayed auction calendar due to the pandemic. But the Phillips catalogue is still 269 lots strong, with a little bit of everything. We took a look at some of the notable complicated watches last week, including the magnificent A. Lange & Söhne Tourbograph that’s a strong value buy in uber-complications. Now, we’ll take a look at some of the timepieces by independent watchmakers as well as a handful of interesting, esoteric, and well-priced watches. You can find the rest of the catalogue here. Lot 806 – Girard-Perregaux Sea Hawk II Pro “Challenger of Record” This sits squarely in the category of weird-but-cool watches. Extremely large at 44 mm, with massive lugs and an even larger crown guard, the Girard-Perregaux Sea Hawk II Pro “Challenger of Record” is a dive watch rated to 3,000 m – three-thousand metres, or 9,800 feet – with a sharply finished, tourbillon-equipped movement. The combination is paradoxical, and slightly silly, but the watch has a peculiar charm, no doubt helped by its affordability (with a low estimate a little under US$20,000). Made in 2006, a time when diving tourbillons were fashionable and when Girard-Perregaux was still a family-run firm owned by the Macalusos – the certificate for the watch is signed by the late Luigi “Gino” Macaluso – the Sea Hawk tourbillon was a limited edition of 32 w...

Grand Seiko Introduces the Soko US Special Editions SJX Watches
Grand Seiko Introduces Jun 13, 2020

Grand Seiko Introduces the Soko US Special Editions

Made exclusively for the American market, the Grand Seiko Soko US Special Editions, like many Grand Seiko watches, are a nod to a Japanese theme or motif. Made up of a pair of Spring Drive watches – the SBGA427 and SBGA429 – with bamboo-green accents, the special edition is named after Soko (霜降), one of the 24 periods of the traditional seasonal calendar. In the Japanese seasonal calendar, the year is divided into 24 periods known as Sekki (節季), each lasting about two weeks. Like any calendars in use before the modern age, the seasonal calendar was based on the solar year, and used by farmers for agriculture. Soko translates as “frost descending”, and marks the end of autumn. Specifically, the two watches take inspiration from Kyoto’s tranquil Arashiyama Bamboo Forest at autumn’s end, translating the scenery into elements of the dial. The Soko SBGA429 Initial thoughts I always love how Grand Seiko encapsulates Japanese concepts or culture in their watches – reflecting a strong national pride – which gives its timepieces an intrinsically distinct style compared to watches from other parts of the world. This is being done more often now that Grand Seiko is being sold widely outside of Japan, especially in the United States. With Grand Seiko gaining traction in America, the brand has produced several special editions available only in the country, such as the Kirazuri and the Japan Seasons special editions – effectively distilling the essence of J...

In-Depth: Konstantin Chaykin and Telling the Time on Mars

When Russian independent watchmaker Konstantin Chaykin announced the Mars Conqueror last year, it was not the first Martian-time wristwatch, but it was by far the most advanced and comprehensive watch to indicate Martian time – and even the Martian calendar. TAG Heuer was appointed the official timekeeper for China’s Mars exploration mission in 2016, with its chief executive Jean-Claude Biver declaring that exploring the Red Planet is “the next giant leap for humanity”. With its launch planned for July 2020, the Chinese journey to Mars is just one of several missions to the planet – Russian space agency Roscosmos and NASA are working on similar projects. Despite the steady progress in reaching Mars, no big watch brand has debuted a watch that tells Martian time. Konstantin Chaykin’s experimental Mars Conqueror of 2019 But such watches have been built, as a matter of necessity for the scientists involved in past Mars missions. NASA’s Mars Exploration Rover (MER) of 2004, for instance, commissioned several watchmakers to construct simple but effective Martian-time watches. Since the Martian day, known as a sol, is 24 hours, 39 minutes and 35 seconds, the solution was to slow a conventional watch to match Martian time. Steve Maddox of North Little Rock converted a second world war, military-issue Hamilton 4992B pocket watch for MER team member Jeff Moersch, reducing its frequency from the standard 18,000 beats per hour (bph) to about 17,525 bph. And Los Ang...
