Ulysse Nardin Introduces the Freak X Ice and Freak X Magma SJX Watches
Ulysse Nardin Introduces Mar 6, 2020

Ulysse Nardin Introduces the Freak X Ice and Freak X Magma

Launched a year ago, the Ulysse Nardin Freak X is the entry point to brand’s landmark Freak collection. The Freak X dispenses with the idiosyncrasies and innovation of its predecessor – though it still boasts a large, high-performance balance wheel in silicon – but makes up for it with a streamlined case and notably affordable price tag. Already iterated into numerous variants, the entry-level watch now available in two additional versions, the Freak X Ice and Freak X Magma. Diametrically opposed in aesthetics, both nonetheless share the same specs: a 43 mm case with gently tapered lugs and most notably for a Freak, a conventional crown, which makes the Freak X more practical all of its larger, crown-less predecessors. Perhaps the more sedate of the two, the Freak X Ice is the first all-white Freak, apart from the experimental Freak nExt concept watch. The Freak X Ice is dressed entirely in matte, brushed metal and matte white. The case is brushed titanium, while the bezel is titanium coated in matte white. And the dial is also matte white, with the central bridge, fixed ring gear and hour wheels in brushed, rhodium-plated brass, creating a contrast against the dial that emphasises the carousel. On the other hand, the Freak X Magma is all about striking contrast of textures. The case is a carbon-fibre composite that is made up of carbon fibres with a red polymer, creating a strong and light material that is scratch-resistant – and one that makes a real statement ...

Obituary: Kiu Tai Yu, Chinese Independent Watchmaker SJX Watches

Obituary: Kiu Tai Yu, Chinese Independent Watchmaker

Born in China but having worked in Hong Kong for decades, Kiu Tai Yu was long reputed to have been the first watchmaker to produce a tourbillon wristwatch in Asia, having premiered his own in 1990. Before that, only watchmakers in the West had ever produced a tourbillon, a device that was then still regarded as the pinnacle of artisanal watchmaking. A year after unveiling his tourbillon, Kiu became the first Asian member of the Académie Horlogère des Créateurs Indépendants (AHCI), the association of independent watchmakers that had been established by Svend Andersen and Vincent Calabrese just a few years before. The news of Kiu’s death was first announced by Mr Calabrese on Facebook. Kiu Tai Yu in his shop. Photo – Vincent Calabrese But it was in 1993 that Kiu debuted his most memorable invention, the Mystery Tourbillon. Equipped with an oscillating balance wheel making one revolution a minute, but seemingly with neither a cage nor bridge. The secret lay in a clear sapphire plate that functioned as the upper bridge, while the cage of the tourbillon was reduced to a fish-shaped platform underneath the balance wheel, a construction that has since been adopted in various forms by brands like Montblanc and Zenith. Not content with a mere Mystery Tourbillon, Kiu subsequently installed the invention in a rectangular form movement, and later even added a jumping hour time display. It’s worth pointing out that every one of Kiu’s tourbillon wristwatches was unique, and ...

In-Depth: Why the Position of a Watch Influences Accuracy

A mechanical watch movement is a tiny-but-complex system made up of components in equilibrium, operating flawlessly. But because the those components are delicate – especially the parts that make up the escapement – its operation can be influenced by external factors,  including shock, moisture, and more commonly, the position of the watch, whether on the wrist or off. The position of a watch determines how gravity affects the moving parts of the movement. In other words, the timekeeping of a watch can vary according to whether it is laid on its back or on its side. That resulting variation is known as positional error, and it is largely because of gravity’s effect on the balance wheel – the oscillator in the regulating organ of the movement. Beyond the position of a watch, positional error is also shaped by factors like the amplitude of the balance wheel, the type of hairspring, and the poise of the balance. All are inextricably linked and must be adjusted just right – properly regulated in watchmaking parlance – in order for a watch to have minimal positional error and thus keep good time. [Editor’s note: In this article we’ll just deal with movements constructed traditionally with conventional materials, leaving out silicon-equipped movements, which are still relatively niche.] The Microstella adjustable-mass balance of the Rolex cal. 4030, which is based on the Zenith El Primero A matter of position The position of a watch significantly affects its ac...

Blancpain Introduces Miniature, Skeleton, Form Movement Cal. 510 SJX Watches
Jaeger-LeCoultre has been Jan 21, 2020

Blancpain Introduces Miniature, Skeleton, Form Movement Cal. 510

Every year Blancpain (as well as its sister company Breguet) debuts a limited edition for Valentine’s Day. The concept is a bit kitschy – the watch is usually decked out in diamonds and hearts – but this year’s edition is a notably interesting watch. The Saint-Valentin 2020 is powered by a newly-developed form movement, the cal. 510, that is both rectangular and skeletonised. While traditionally Jaeger-LeCoultre has been the leader in form movements for ladies’ watches, most notably with the tiny cal. 101 and with other movements found in the Reverso as well as various Cartier Tanks, Blancpain has notched up a win in the segment with the cal. 510. The cal. 510 is relatively large for what is supposed to be a small movement for a ladies’ watch, measuring 12 mm wide and 25.2 mm long. But it is impressively constructed. It’s fitted with a good-sized barrel that gives it a 50-hour power reserve, which is lengthy for such a tiny movement. That is especially so considering the relatively large balance wheel that is free-sprung and equipped with hour regulating weights on its recessed rim. Additionally, the bridges are all open-worked, revealing the going train and barrel ratchet wheel. The result is also an obvious two-tone look, with the gilded wheels contrasted against the rhodium-plated bridges. And the components are finished carefully and completely, although it appears some of it is done by machine. The rest of the watch is arguably less interesting than ...

The Most Notable Watches of 2019 SJX Watches
Citizen Caliber 0100 slightly plain but Dec 30, 2019

The Most Notable Watches of 2019

Oddly enough, one of the year’s highlights is a quartz watch that costs almost US$17,000 – but it is the most accurate wristwatch ever, rated to run within a second a year and probably less in practice. The Citizen Caliber 0100 slightly plain but the technology within is mighty impressive. Also impressive is the thought and effort put into developing the movement; that is extremely Japanese. It feels slightly anachronistic given the alternatives that can sync with GPS or radio waves and keep just as good time, but it is still mighty impressive. The top of the line model is in 18k white gold, explaining the price tag, but fortunately there’s a titanium model with the same movement for half the price. The Citizen Caliber 0100 The 0100S movement Sporty-ish and value For almost exactly the same price, the Bulgari Octo Finissimo Chronograph scores high in terms of value for money. It’s an ultra-thin – really, really thin – chronograph with a second time zone function that continues Bulgari’s streak of extra-flat Octo watches. Though the design is thoroughly modern, its slimness and proportions give it a graceful air. But at 42mm the case is verges on looking like a biscuit because it is flat and wide. And the thinness of the movement, combined with a rather small balance wheel, inevitably invite questions about its robustness. The Octo chronograph That is very flat More expensive but also strong value for money is the A. Lange & Söhne Odysseus. Looks-wise, it...

MB&F; Introduces the Legacy Machine 101 in Palladium SJX Watches
Breguet overcoil Visible through Nov 23, 2019

MB&F; Introduces the Legacy Machine 101 in Palladium

In 2014, MB&F; unveiled the Legacy Machine 101 (LM101), its most affordable classically-styled watch, but nonetheless equipped with a beautifully executed, hand-wound movement that had its styling and decoration conceived by Kari Voutilainen. Several editions later, including the pair of “Frost”watches and one in platinum, the brand unveils the Legacy Machine 101 Palladium. Limited to 18 pieces, the watch has the same dimensions as the earlier versions of the LM101, so the case 40mm wide, making it the smallest Legacy Machine. It is made of palladium, a bright white metal that resembles platinum – they are both in the same family of metals – but is considerably lighter, yet harder and more resistant to scratches. The case has a polished top surface on the lugs and bezel, with a contrasting brushed case band. It is combined with a pale blue, sunray-brushed dial, on which time is indicated on a sub-dial at two o’clock and a power reserve on a smaller sub-dial at six o’clock. Both sub-dials are in white lacquer with printed markers, giving them a vague resemblance to porcelain dials on antique pocket watches. Like all other Legacy Machines, the balance wheel is suspended high above the dial by an arched balance bridge. The balance is 14mm large with four adjustable weights for regulation and a hairspring with a Breguet overcoil. Visible through the sapphire case back, the movement demonstrates a significant degree of fine finishing and classical details, no doub...

Patek Philippe Introduces the Aquanaut Singapore 2019 Ref. 5167A-012 (With Pricing) SJX Watches

Patek Philippe Introduces the Aquanaut Singapore 2019 Ref. 5167A-012 (With Pricing)

Since its introduction in 2007, the popularity of the Aquanaut 5167A has followed on the coattails of the Nautilus Ref 5711/1A. And now for the occasion of the Watch Art Grand Exhibition in Singapore, Patek Philippe has unveiled a special-edition Aquanaut ref. 5167A-012 with red accents and a red strap. The dial features the Aquanaut’s traditional chequerboard motif, but with red minute markers and a red central hand. The addition of colour is a nod to Singapore’s flag, which is red and white. Though the cosmetic changes are minimal, the overall effect of which is nonetheless striking and appealing. Depth rated to 120m, the case remains 40mm in diameter and is paired with a red composite strap. It houses the cal. 324 S C, which is visible through a sapphire case back that has been printed with the inscription “Patek Philippe Singapore 2019”. The cal. 324 S C is the brand’s central-rotor automatic movement that is fairly ordinary but attractively finished. It offers a short 35- to 45-hour power reserve, and as with all of Patek Philippe’s current movements, it is fitted with a Gyromax balance wheel, which is essentially a free-sprung, adjustable mass balance, as well as a silicon Spiromax hairspring. Key facts Diameter: 40mm Height: 8.1mm Material: Stainless steel Water-resistance: 120m Movement: cal. 324 S C Functions: Hours, minutes, seconds; date Winding: Self-winding Frequency: 28,800bph, or 4Hz Power reserve: 35 to 45 hours Strap: Red composite Pr...

De Bethune & Urwerk Introduce the Moon Satellite for Only Watch 2019

When Urwerk cofounder Felix Baumgartner was in town recently to launch the UR-100 SpaceTime, I quizzed him on the De Bethune and Urwerk collaboration for Only Watch 2019. While the other brands taking part in the charity auction had already unveiled photos or renderings of their respective creations, Urwerk and De Bethune only offered a pen drawing. Felix replied that the movement had been completed and delivered to De Bethune some weeks ago, and Denis Flageollet, De Bethune’s resident technical genius, was working on building the one-off titanium case. And now Mr Flageollet has completed the watch, and this is it. The initial drawing The meeting of minds Named the Moon Satellite, the watch is essentially an Urwerk wandering hours time display module – with the time indicated on satellites – mounted on top of a hand-wound De Bethune movement, resulting in the cal. DBUR2105. Visually the movement is trademark De Bethune. The calibre has a delta-shaped barrel bridge that is entirely mirror polished, as is the base plate, one of the most distinctive movement treatments of De Bethune. And in striking contrast against the polished surfaces, the balance and shock absorber bridges are in blued steel. The base movement cal. DB2105 boasts several of De Bethune’s patented innovations, including a spider-like titanium balance wheel, the triple pare-chute shock absorber for the balance, as well as the De Bethune hairspring and silicon escape wheel. And it also incorporat...

Vacheron Constantin Introduces the Cornes de Vache Chronograph in Steel SJX Watches

Vacheron Constantin Introduces the Cornes de Vache Chronograph in Steel

Originally available in platinum and then rose gold, the Vacheron Constantin Historiques Cornes de Vache 1955 is a well regarded vintage remake, being well executed and faithful to the original. It’s modelled on the ref. 6087 of the 1950s, which was characterised by pointy, horn-shaped lugs, hence the model name; cornes de vache translates as cow horns. Now it is available in stainless steel, making the Cornes de Vache the second Historiques model to be offered in the metal, after the Historiques 1942 and 1948 triple calendars. The steel case naturally makes it far more accessible, with a retail price that’s a third less than the same in platinum. Material aside, the specs of the new model are identical to the earlier precious metal versions. The case is 38.5mm in diameter, and contains the cal. 1142 movement. Now made in-house by Vacheron Constantin, the cal. 1142 is derived from the Lemania 2310. Vacheron Constantin has upgraded the movement in several ways, most notably with a free-sprung balance wheel. The dial is a pale grey with a fine “velvet” finish and red accents on the elapsed seconds track. All of the applied hour markers are 18k white gold, as are the hands. Notably, this is not the first Cornes de Vache in steel. In 2017 Vacheron Constantin produced a small run of 36 watches – with a steel case and dark grey dial – for American watch blog Hodinkee.

Audemars Piguet De Bethune Aug 29, 2019

Hands-On: Ulysse Nardin Freak X Carbonium Gold “The Hour Glass”

Having unveiled commemorative editions from the likes of Audemars Piguet, De Bethune and Urwerk for its 40 years in business, Singapore watch retailer The Hour Glass continues the anniversary roll-out with the Ulysse Nardin Freak X Carbonium Gold. The watch is a variant of the entry-level but appealing Freak X, a remarkable exercise in simplicity and the most affordable version of the Freak to date. But importantly, it manages to be the base model without being a concession, and instead is more of an optimisation, offering a great deal of exotic watchmaking – it boasts the fanciest oscillator of any watch in this price segment – for little money as such things go. While the Freak X forgoes some characteristics of its avant-garde forebear, it is both technically clever and much more refined in design, offering an enhanced practicality by way of a smaller case, a traditional crown, an automatic movement, and most crucially, a high-performance silicon balance wheel – an innovation found only in one other Freak, the pricier Freak Vision. Streamlined mechanics Limited to 30 pieces, the Freak X for The Hour Glass combines a new case material – “Carbonium Gold” – with a striking champagne dial. In contrast to most Freak models that have dark dials, this Freak X has a face in a pale gold which gives it a greater presence on the wrist, but because of its matte, brushed finish, it isn’t loud and manages to be easily wearable. The only downside of t...

Longines Introduces the Master Collection Moonphase SJX Watches

Longines Introduces the Master Collection Moonphase

Longines’ Master Collection excels at entry-level complications that are affordably priced – last year’s annual calendar is a great buy – and the latest in the range is a moon phase and date. The Master Collection Moonphase is a watch that’s clear in what it wants to to. Aside from the time, it has a pointer date and moon indicators in a sub-dial at six, for a clean and symmetrical dial. The Master Collection Moonphase ref. L2.919.4.78.3 It’s powered by the L899 movement, an automatic based on the ETA A31.L91, which is an upgraded version of the common ETA 2892. The most obvious functional upgrade is the extended 64-hour power reserve, achieved in part by reducing the beat rate of the balance wheel from 4Hz to 3.5Hz. Like many other models in the Master Collection, the new moon phase is offered in two cases sizes – 40mm and 42mm – both in stainless steel. Dial options are silvered barleycorn guilloche, black barleycorn, or sun-ray brushed metallic blue. The smaller, 40mm case is also offered with brilliant-cut diamond hour markers on all dial styles.

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...

Up Close: Ulysse Nardin Executive Tourbillon Free Wheel

With the Freak being the undisputed flagship complication of Ulysse Nardin – as well as a historically important watch – many of the brand’s other technical accomplishments often go under the radar. One intriguing offering that hasn’t gotten much attention: the Executive Tourbillon Free Wheel. Despite the somewhat dull name, the Tourbillon Free Wheel is a compelling reinterpretation of a mystery clock – where the mechanics are artfully hidden and exposed for visual effect – that is both fascinating and exotic. The Executive Tourbillon Free Wheel with an aventurine dial While the base model of the Executive collection features a largely conventional, open-worked movement, the Tourbillon Free Wheel takes things a step further by elevating the crucial parts of the movement like the barrel, tourbillon regulator, and gear train for the power reserve. In fact, most of the components are “floating” – the movement boasts a flying tourbillon, a “flying” gear train and power reserve indicator, as well as a “floating” barrel. At the same time, the construction is inverted, with parts that are usually hidden sitting exposed, and vice versa. As a result, the tourbillon and power reserve display appear to operate in isolation, with no obvious connection to the rest of the movement. Floating and flying minimalism While much of the gearing is hidden underneath the dial – which doubles up as the base plate – most of the moving parts are “floating” –...
