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...

Up Close: Purnell Escape II Double Tourbillon
Given that the tourbillon was invented for the pocket watch, adapting Abraham-Louis Breguet’s invention for the wristwatch opened the floodgate for tourbillon innovations in the beginning of the 21st century – the golden age of the tourbillon, perhaps technically but surely commercially. In fact, many watchmakers have gone far beyond the traditional concept of a tourbillon since English watchmaker Anthony G. Randall invented the double-axis tourbillon in 1978. But as the years passed, tourbillons evolved into elaborate constructions seemingly just for the sake of visual complexity. And there have been so many of them. For this reason, exotic tourbillons now seem dated, with sophisticated or truly interesting technical solutions being hard to come by. Potter and Purnell But the latest development in tourbillons is one of the most intriguing of recent times: maximising the visual effect of a tourbillon regulator not just by multiplying the axes of rotation, but speeding them up with the use of a specialised escapement invented two centuries ago by Albert H. Potter, a highly regarded American watchmaker based Geneva. The full potential of the Potter escapement was recently realised when it was combined with a carrousel outer cage in the MB&F; LM Thunderdome, the world’s fastest rotating triple-axis tourbillon. But the concept was first applied, arguably in a more elaborate manner, in the Spherion tourbillon of Purnell – which was developed by the same watchmaker behin...

Hands-On: Brivet-Naudot Eccentricity
French watchmaker Cyril Brivet-Naudot made his debut two years ago with the Eccentricity, a time-only watch that’s fascinating and impressive on many fronts. Not only is it almost entirely made by hand, the Eccentricity is intriguing in design and mechanics – from the overall architecture to details like the key-winding mechanism and regulator-style time display with a twist, and above all, the proprietary escapement. Just 29 years old, Mr Brivet-Naudot began working on the Eccentricity after graduating from the École Polytechnique Fédérale de Lausanne (EPFL), one of Switzerland’s best technical universities. Prior to that, he earned a diploma in watchmaking from the Lycée Edgar Faure in Morteau, a small town in eastern France that borders Switzerland. The school has gained a reputation for producing imaginative watchmakers, many pursuing a similar style that’s inspired by 19th century pocket watch movements, including Theo Auffret, a peer of Mr Brivet-Naudot. The result of three years of development, the Eccentricity is very much in the same vein as the watches produced by Mr Brivet-Naudot’s fellow graduates. It artfully combines a 19th century aesthetic sensibility with exotic features, including a novel, free-eccentric escapement, for which the watch was named. And it is built by hand: with the exception of the mainspring, hairspring, jewels and crystals, every component of the watch was made from scratch by Mr Brivet-Naudot, without the aid of CNC machine...

Breguet Introduces the Marine Tourbillon Équation Marchante 5887
One of the most exotic Breguet watches in production today, the Marine Tourbillon Équation Marchante 5887 combines a tourbillon regulator, perpetual calendar, and running equation of time. Complexity aside, the watch is mechanically fascinating: the traditional complications within are executed in a modern and practical way. The equation of time, for instance, relies on an open-worked cam produced via the high-tech LIGA photolithography technique. And the tourbillon cage is lightweight titanium with a silicon escapement, while the automatic winding is equipped with a peripheral rotor. Breguet has now introduced a new version of the grand complication, in pink gold with a slate-grey dial. While it is mechanically identical to the two earlier versions – in platinum with a blue dial or pink gold with a silver dial – the new watch is striking and harmonious, shedding a bit of the sports-watch aesthetic of the Marine by way of the richer colours. Being a facelift, the dimensions of the watch remain unchanged. It is still a massive 43.9 mm in width, though a svelte 11.75 mm high, thanks to the ultra-thin movement inside. Like the movement, aesthetics across the case and dial are very much a blend of new and old. The case has the traditional fluted band, but is paired with modern integrated lugs. Similarly, the dial is solid gold and decorated with traditionally-executed guilloche engraved with a rose engine, but in a modern, stylised wave motif. In a nod to the age-o...

Hands-On: Ulysse Nardin Diver X Cape Horn and Nemo Point
Dive watches priced below US$10,000 are one of the saturated and competitive segments in watchmaking. The category is dominated by two dive watch icons, the Rolex Submariner and the Omega Seamaster, both of which set the bar high with high-spec, in-house escapements equipped with high-tech hairsprings and next-level chronometer certifications. Ulysse Nardin smartly steered away from the conventional dive-watch look with last year’s new Diver X. Created to mark the brand’s newly-forged partnership with Vendée Globe, a non-stop solo yacht race around the globe, the Diver X Cape Horn and Diver X Nemo Point are a contemporary take on the standard Diver Chronometer 44mm, dressed up in new materials and colours but retaining the same basic specs, namely a 300 m rating and an in-house movement with a proprietary escapement. The Diver X Cape Horn Dubbed the “Everest of the Seas” because of its reputation as the toughest sailing competition in the world, the Vendée Globe is such an arduous journey that the eight races since 1989 have claimed three lives. Competitors have to travel over 40,000 km, a round-the-world trip that takes between two to four months. Unsurprisingly, the twin Diver X editions are aggressively styled and technically robust. Form and function Each named after key points along the Vendée Globe route, the Cape Horn and Nemo Point have the longstanding, symmetrical layout of a Ulysse Nardin diver’s watch – originally inspired by the dial of the br...

In-Depth: The Unfinished George Daniels Watch
George Daniels’ contributions to horology, as a watchmaker, historian and educator, were multi-dimensional. Most are widely known, and his watches are now incredibly valuable. But one of his creations – the “Unfinished Daniels” – remains tantalisingly incomplete, residing in the Clockmakers’ Museum within London’s Science Museum (which is also now home to Daniels’ Space Traveller II pocket watch). Even though he completed only a small number of watches – 23 pocket watches and four wristwatches made by hand, along with the serially-produced Millennium watches – Daniels’ inventions, techniques and philosophy have been deeply influential. His successor Roger W. Smith now practices the Daniels method with his own hand-made watches, but other notable watchmakers, including Francois-Paul Journe, have cited Daniels as an inspiration. The unfinished Daniels movement in the George Daniels exhibit in the Clockmakers’ Museum. Photo – Science Museum Like many great watchmakers over the ages, Daniels’ pursued perfect chronometry throughout his career; inventing a novel, superior escapement was perhaps his greatest achievement. And he managed to do it twice. Having observed that the sliding friction in the conventional Swiss lever escapement affects the rate of a movement over time, he set about developing solutions. He invented two escapement types: one inspired by a 18th century Abraham-Louis Breguet idea, while the other was the entirely original and mo...

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.

Recommended Watching: Roger W. Smith Explains History of the Mechanical Watch
Just over two weeks ago the annual George Daniels lecture took place at the City University of London, an institution supported by the late watchmaker’s charitable trust. This year’s speaker at the sold-out event was none other than Roger W. Smith, protege and successor to Daniels. Just over an hour long, including questions, the lecture is erudite, accessible and packed with nerdy trivia, like the fact that a movement running at 28,800 beats per hour will make 252,288,000 vibrations per year. Roger explained the history and rationale behind the mechanical watch, and how watchmakers are working to improve it even today. That naturally led into the lubrication-free co-axial escapement invented by Daniels (pictured above), which Roger delves into in a satisfyingly detailed manner, like comparing the sliding friction of a lever escapement against the tangential impulse of the co-axial. Fortunately, the entire proceedings were recorded and are now available online:

Auction Watch: Breguet Skeleton 30-Day, Constant Force Clock by Philippe René Jaccard
One of the most intriguing timepieces being offered in the final run of watch auctions for 2019 is not a wristwatch, but an incredibly rare table clock made by Breguet in 1934 that’s going under the hammer at Christie’s. It hardly looks like a typical Breguet – having no engine-turning or gilding or blued steel hands – but is remarkably striking, with a skeletonised, architectural movement that is modern-looking despite being 85 years old. Abraham-Louis Breguet is rightly regarded as one of the most important watchmakers in history, whose inventions range from the natural escapement to the tourbillon, while being commercially savvy enough to become a leading watchmaker to the Ottoman Empire. But his descendants ventured into other businesses by the mid 19th century, most notably aviation, so the watchmaking operation was sold by Louis-Clément Breguet, grandson of Abraham-Louis, in 1870 to English watchmaker Edward Brown. The Browns kept the workshop in Paris, though it moved several times over the decades. During the century that the Brown family ran Breguet – Brown’s grandson George sold the company to French jeweller Chaumet in 1969 – the firm mostly retained the signature Breguet style and produced a large variety of timepieces, but in tiny quantities, often relying on external specialists for movements and components. Timepiece no. 3142 This clock is one such timepiece from the period. A unique piece according to the accompanying Breguet museum archive...

In-Depth: MB&F; LM Thunderdome Triple-Axis Tourbillon
The flying tourbillon wristwatch for women – the Legacy Machine FlyingT – that MB&F; launched last year foreshadowed its latest watch – the Legacy Machine Thunderdome, boasting the fastest ever triple-axis tourbillon developed by independent watchmaker Eric Coudray. No doubt multi-axis tourbillons are hardly new, especially after Jaeger-LeCoultre unveiled its first Gyrotourbillon in 2005 – which was also developed by Mr Coudray – but the LM Thunderdome takes the concept further by every metric, primarily by building on past ideas to achieve higher cage velocities than ever before. Most intriguingly, the Thunderdome movement incorporates a tourbillon lever escapement first devised by Albert H. Potter – a talented American watchmaker who worked in Geneva in the late 19th century – as well as an unusual multi-axis tourbillon that utilises a carrousel for its outermost cage, christened the TriAx. The ingenious construction of the tourbillon is thanks to Mr Coudray, who now runs complications workshop TEC Ebauches and is best known for the numerous exotic tourbillon movements he has developed. After his two-decades at Jaeger-LeCoultre where he became the resident technical genius, Mr Coudray worked for several brands of varying levels of credibility, including at Cabestan where he perfected its vertical tourbillon, and more recently at Cecil Purnell, where he created the Spherion tri-axial tourbillon, which has a similar construction to the Thunderdome.

Zenith Introduces the Defy El Primero 21 Southeast Asia Editions
Produced for the key markets in an important region, the Defy El Primero 21 South East Asia Edition is based on Zenith’s well-priced, 1/100th of a second chronograph, with one edition each for Singapore, Indonesia and Malaysia. All three watches share the same red and white livery – reflecting the colours found in each country’s national flag – but with a respective national landmark printed on the case back. The Defy El Primero 21 is one of two true 1/100th of a second chronographs on the market that are serially produced – the other being the Mikrograph produced by Zenith’s sister company TAG Heuer. Both share a similar movement architecture, but the Mikrograph came first and inspired the construction of the Zenith calibre. Landmarks The colour scheme of the trio is a nod to the flag of each country, all of which happen to include red and white. The power reserve, minute counter, chronograph hands and crown are accented in red. The watch is otherwise mechanically identical to the standard version. It is powered by the self-winding El Primero 9004 movement, which utilises two independent sets of mainsprings, gear trains and balance wheels. The timekeeping escapement runs at a frequency of 5Hz, while the chronograph escapement runs at 50Hz, allowing the watch to resolve to 1/100th of a second. And more so important in a high frequency movement, the escape wheels – the fastest rotating wheel in the transmission system – and pallet forks are made of silicon...

Introducing the Hasta la Vista Revolver 8-Day Table Clock
A recent startup dedicated to creating unusual objects, The Unnamed Society makes its debut with a table clock shaped like the Colt Bisley Model revolver of the early 20th century. The clock is produced by L’Epee 1839, the Swiss clockmaker that is responsible for practically all of the unconventional and avant-garde mechanical clocks of recent years, most famously those designed by MB&F; but also Chanel. But it’s undoubtedly the success of MB&F;’s sci-fi clocks that have compelled various brands, old and new, to develop their own L’Epee 1839 clocks. Named Hasta la Vista, “goodbye” in Spanish, the clock is the shape and size of an actual revolver, measuring 350mm or just under 14 inches long. It’s made of steel and palladium-plated brass, and can be mounted on its accompanying base either via the grip or the barrel. Pictured here with the grip made of horn from the bighorn sheep, as well as engraving on the frame Mechanically it is identical to the 8-day clocks L’Epee 1839 has produced in other shapes and sizes. The time is indicated by two revolving cylinders – one each for the hours and minutes – that take the shape of the rear section of the pistol frame. The escapement, wheel train and mainspring are where the cylinder (which contains the bullets) would be. Winding is accomplished by a key that’s inserted into the end of the barrel. Though it’s a limited edition of 50, each clock can be customised with a variety of options offered for the g...

Hands-On: Zenith Defy El Primero Double Tourbillon
When Zenith unveiled the El Primero Defy 21 two years ago, it was a breakthrough for the brand, offering a 1/100th of a second chronograph with twin regulators for an affordable US$10,000 or so. This year the brand has kicked things up a notch with the El Primero Defy Double tourbillon, which essentially replaces the regular escapements with two tourbillons – one conventional and the other ultra-fast. The high-frequency evolution The new double tourbillon chronograph is a logical evolution of the classic El Primero – albeit accomplished with some help from TAG Heuer – that remained unchanged for decades. Unveiled 50 years ago, the El Primero was the first integrated automatic chronograph, and crucially, the first serially-produced, high-frequency chronograph running at 36,000 beats per hour (bph), allowing it to measure time down to the nearest tenth of a second. It would take 48 years for it to evolve into its first major iteration, the El Primero Defy 21 of 2017, which took the high-precision chronograph to its extreme with a monstrously high frequency of 50Hz, capable of measuring time down to a hundredth of a second. The Defy El Primero 21 launched in 2017 – an exotic chronograph for a basic price While it is true that a higher frequency regulator results in a higher resolution chronograph, it comes at a cost. An ultra-high frequency escapement requires tremendous energy, and the friction generated by the rapid motion of its components in turn mean more f...

Up Close: Cartier Astromysterieux
In 2016, Cartier unveiled one of the most dramatic examples of an orbital regulator – the Astromysterieux – in which the entire movement was suspended in the oculus of the watch dial, mysteriously unencumbered by any visible support. The Astromysterieux sits in the same class of exotic regulators as the Ulysse Nardin Freak, Piaget Tourbillon Relatif, and Jean Dunand Tourbillon Orbital – and unsurprisingly, three of the four were conceived by the same watchmaker. Previously only available in palladium, the brand has now introduced a striking pink gold version with a black guilloche chapter ring. The dimensions of the watch remain unchanged – 43.5mm in diameter with a thickness of just 12mm, making it one of the thinnest, most elegant watches with such an unusual regulator. In the new pink gold version, the black guilloche chapter ring is paired with polished pink gold roman numerals and black Breguet-shaped hands, creating a remarkable contrast. But the true brilliance of the watch lies in the ingenious cal. 9462 MC, for which three patents were filed. The secret to the floating, mysterious movement is in the invisible gearing that is hidden behind the chapter ring. The movement is essentially baguette-shaped, with the minute hand fixed to the barrel bridge, and completes a full rotation on the dial in an hour.
