Ulysse Nardin Debuts the Marine Torpilleur 175 Years Collection SJX Watches
Ulysse Nardin Debuts Sep 1, 2021

Ulysse Nardin Debuts the Marine Torpilleur 175 Years Collection

Historically a major producer of marine chronometers, Ulysse Nardin has repurposed the concept in the modern day for its bestselling line of wristwatches that retain the face of a marine chronometer while having in-house movements and eminently reasonable prices. For its 175th anniversary, Ulysse Nardin has unveiled the Marine Torpilleur 175 Years collection, a suite of limited-edition watches starting with an affordable base model and ending with a range-topping tourbillon featuring a fired-enamel dial. Initial thoughts Originally introduced as an entry-level Marine model – it was named after a torpedo boat – the Marine Torpilleur has been successful enough that it’s now an entire anniversary line up. The expansion of the line is a good thing, because the Torpilleur is classically handsome and generally good value. All the Torpilleur models are largish at 42 mm in diameter, but most are slim, with heights of about 11 mm, though the chronograph is understandably wider and thicker. As a result, they appear relatively thin on the wrist, especially for a sporty watch. The tourbillon with a black enamel dial, and next to it a vintage Ulysse Nardin chronometer pocket watch with tourbillon regulator And the watches are all equipped with high-spec in-house movements, which is a big factor in their value propositions. Even the base model, which costs US$8,200 in its simplest version, is equipped with the UN-118, a movement that has a silicon hairspring and escapement, along...

Bernhard Lederer Introduces the Central Impulse Chronometer SJX Watches

Bernhard Lederer Introduces the Central Impulse Chronometer

After Bernhard Lederer unveiled his impressive double-wheel escapement wristwatch last year, it was radio silence until now. As it turns out, Mr Lederer was working on refining the Central Impulse Chronometer, which is now being launched in its final, serial-production form. The new watch is essentially the same watch, but with a new and improved dial. The movement remains the same: equipped with a double-wheel escapement featuring twin going trains, each equipped with a remontoir d’egalité constant force mechanism – making it one of the serious chronometers in modern horology. Entirely revised is the dial, which now has more elegant design, with slim hour markers framing a chequerboard guilloche centre. And the dial now incorporates gains a symmetrical, figure-of-eight aperture that showcases the twin escapements and remontoirs, with each having its own seconds hand – both turning in the opposite direction. Initial thoughts The CIC is one of the relatively rare wristwatches to incorporate a double-wheel escapement. But what makes the CIC uncommon is its execution – its escapement is powered by twin individual going trains – a construction famously conceived by George Daniels for his pocket watches, most notably the Space Traveller’s Watch. Bernhard Lederer at his bench The degree of miniaturisation to fit such a construction into a watch puts the CIC amongst an exclusive class of timepieces that can be counted on one hand – made by George Daniels, Derek ...

In-Depth: The Rolex Chronergy System SJX Watches

In-Depth: The Rolex Chronergy System

Rolex launched Chronergy – essentially a mechanical ecosystem for optimal mechanical performance – with the cal. 3255 in the top-of-the-line Day-Date 40 that made its debut in 2015. Six years on, Rolex has upgraded practically its entire line up with latest-generation, Chronergy-equipped cal. 32XX family, including its most affordable offerings. Chronergy movements are found in the Datejust (cal. 3235) and Oyster Perpetual (cal. 3230), and also the entry-level sports watches, like last year’s Submariner ref. 124060 (cal. 3230). Chronergy is made up of 14 patents covering every aspect of a movement from power source to regulator, but a fundamental element is its escapement. And the Chronergy escapement actually continues a long-forgotten journey that began some fifty years ago on the other side of the world. Still sound at 300 years old Invented in the mid 1750s by Thomas Mudge (1715-1794), the lever escapement was arguably the necessary iteration of the deadbeat escapement once it was miniaturised for a watch. Having been conceived by George Graham (1673-1751) as a refinement of the anchor escapement in pendulum clocks, the deadbeat escapement was unsuited to the delicacy of watch proportions. In the lever escapement, impulse is provided to the balance via a lever, which is in turn propelled by the force of the escape wheel teeth contacting the pallet jewels of the lever. And the lever escapement is a detached escapement, meaning the escape wheel locks free of ...

Grand Seiko 60th Anniversary Hi-Beat SLGH003 May 3, 2021

Up Close: Grand Seiko 60th Anniversary Hi-Beat SLGH003

Last year’s 60th anniversary was a major event for Grand Seiko, which unveiled several new movements and plenty of limited editions to mark the occasion. The most notable launch was probably the 9SA5 movement, a high-frequency and high-end automatic calibre. The movement made its debut in the luxe yellow-gold SLGH002, then in the steel Grand Seiko 60th Anniversary Hi-Beat SLGH003 a few months later. Since then the movement has been installed in a similar, but even more pricey platinum edition, and finally the regular production “White Birch” SLGH005. The cal. 9SA5 All the models are essentially the same, save for different dial finishes and case materials. Here we take a close look at the SLGH003 in steel as a representative for the “SLGH” family. Like its siblings in the family, the SLGH003 is a brand-new reference. The case and dial designs evolved from the existing and familiar Grand Seiko style, but inside is a radically new movement – the cal. 9SA5 with a Dual Impulse escapement. The aesthetic changes have created more refined exterior that better showcase the brand’s case finishing, but more crucially, the improvements signify the brand’s moves upmarket – exemplified by the more elaborate movement and higher price tag. The SLGH003 Initial thoughts Unique among the Grand Seiko line up in terms of its movement and styling, the “SLGH” family boasts new features that are mostly for the better, such as the more elaborate case and sophisticated mov...

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...

Insight: Patents in Watchmaking SJX Watches

Insight: Patents in Watchmaking

Patents in watchmaking are often brushed over by the brand themselves, except when tallying them in marketing material. But they are important, and can be foundational to a brand, as George Daniels’ famed co-axial escapement is synonymous with Omega. But there is a great deal more in watchmaking that can be protected with a patent than a lubrication-free escapement. A large proportion of the parts that make up a watch – from case materials to time-display mechanisms – can be patented, and often are. That begs the question: what exactly can be patented? The common obstacle encountered by a would-be inventor is that patents are notoriously difficult to secure, especially if applied for without specialist help. Going from application to approval of a patent often requires several years, and approval is not a certainty. Gaining a patent hinges on three criteria: the invention in question must be new, non-obvious, and useful. Beyond the necessary knowledge of prior inventions – in order to prove the patent-pending idea is new – the incredibly specific wording required for patents can be daunting to an independent applicant, so it usually falls to a patent attorney to lead the application process. But patents can be lucrative for an inventor, especially for an innovation targeted at the consumer, which is why new patents are registered every day. The United States Patent and Trademark Office, for instance, received just under 670,000 patent applications in 2019, and gr...

Year in Review: The Best Watches of 2020 SJX Watches
Chopard Dec 31, 2020

Year in Review: The Best Watches of 2020

As it was with independent watchmaking, 2020 was a surprisingly good year for the establishment brands. Even though there were practically no in-person launches of new products – with the notable exception being Watches & Wonders in Shanghai – mainstream watchmakers did still debut notable timepieces. Here’s my take on the standouts of the year, starting with the might FB 2RE from Ferdinand Berthoud, a niche name that is nonetheless a subsidiary of Chopard (and the pet project of its co-president Karl-Friedrich Scheufele). Magnificent both in mechanics and decoration, the Ferdinand Berthoud Chronomètre FB 2RE is the watch of the year. Clearly developed a no-expense spared wristwatch, the FB 2RE is at heart a time-only watch constructed for chronometric perfection. It’s equipped with both a a remontoir d’egalite as well as chain and fusee in order to ensure a constant output of energy from the barrel, as well as a constant delivery of energy into the escapement. Both of its key feature are put on show in the symmetrical and architecturally expansive movement, which has all of its key components sitting above the main plate. The FB-RE.FC movement Located just below the balance wheel, the remontoir is particularly fine, made up of slender steel components that are clearly artisanal in manufacture and finish. The quality of finishing extends to the rest of the movement, which is impeccably decorated in every single aspect. In fact, the quality of the movement is com...

Our Predictions In The Chronometry Category Of The 2020 Grand Prix d’Horlogerie de Genève (GPHG): Our Panel Is United, But Not Unanimous

In the GPHG Chronometry category, we find mechanical watches that contain at least one tourbillon, and/or a special escapement, and/or another development improving precision timekeeping. What we don't find, though, is much hard data regarding precision like timing test results or in most cases even a second hand. Precision watches without a second hand? Despite that, our panel predicts a clear winner.

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 ...

Ulysse Nardin Blast Tourbillon Ulysse Nardin Sep 5, 2020

Up Close: Ulysse Nardin Blast Tourbillon

Ulysse Nardin (UN) excels at excellent in-house movements, even for its most affordable, time-only watches. Its watches cases, on the other hand, are typically straightforward – they do the job, but are far from fancy. Just launched at Geneva Watch Days, the Blast Tourbillon is a step in the fancier-case direction. Fronted by a strikingly facetted – and contrast finished – upper plate, the case of the Blast is novel without being too much (though it is a bit much combined with the “X” skeleton movement). And the Blast also sits surprisingly well on the wrist despite its large size. But true to UN’s technically-oriented watchmaking, the Blast is not merely new livery for an old movement. Instead the UN-172 movement within is a new calibre featuring an extensively skeletonised construction – that retains the “X” motif the brand is overly fond of – as well as the signature full-kit silicon oscillator. Initial thoughts The Blast combines an interesting case with an elaborate movement – automatic, skeletonised, and a tourbillon featuring a silicon escapement and hairspring – for not very much money as such things go. With the base model retailing for US$44,000 for the base model, the Blast is priced well. The case is the highlight – finished well and wearable despite its size. The Blast is a big watch at 45 mm in diameter, though it feels notably slimmer than its 13 mm height, partly due to the case height-to-diameter ratio. The fit is good for a wat...

Bernhard Lederer Debuts the Central Impulse Chronometer Prototype

A member of the Académie Horlogère des Créateurs Indépendants (AHCI) since its founding in 1985, Bernhard Lederer is a veteran of independent watchmaking. Though known amongst collectors for having founded the brand BLU in 2002, Mr Lederer is more of a watchmaker’s watchmaker, supplying movements and complications via his company MHM (short for “Manufacture de Haute Horlogerie et Micromécanique”). Born in Germany but based in Switzerland for decades, Mr Lederer’s technical prowess is on full view with his latest creation – the Central Impulse Chronometer (CIC). Seemingly a mere three-hand wristwatch on the front, the CIC is a actually a significant accomplishment – and undoubtedly one of the most notable watches of 2020 from a technical perspective. The movement is equipped with a natural escapements as well as dual gear trains. The construction is familiar – Mr Lederer describes it as a tribute to the late George Daniels and his landmark Space Traveller pocket watch – but improved and refined with the addition a remontoir d’egalité constant force mechanism for each going train. Initial thoughts With seemingly everything already having been done in watchmaking, it is not often that we encounter a genuinely interesting – and improved – twist to an already uncommon escapement. Here Mr Lederer rejuvenates the centuries-old idea of the natural escapement, but elevated by the added complexity and performance gains of twin remontoir going tr...

Insight: Barraud’s Weight and the Marine Chronometer

Although precision watchmaking is today mostly synonymous with Switzerland, the oft forgotten truth is that much of the technological progress and development in horology during the 18th and early 19th centuries originated in England. The preeminence of English watchmaking during that period is perhaps personified by John Harrison, the carpenter-turned-clockmaker best known for his invention of the marine chronometer. Harrison and his contemporaries advanced horology in an era where the pursuit of accurate timekeeping was of national importance for the United Kingdom: the marine chronometer enabled ships to traverse the highs seas while maintaining positional accuracy over extremely long distances, an achievement that no doubt helped the rise of the globe-spanning British Empire. The curious chronometer On a recent visit to Charles Frodsham & Co Ltd. – the English chronometer manufacturer now run by Philip Whyte and Richard Stenning that’s making wristwatches equipped with a natural escapement – a rather curious timekeeper from England’s heyday as a watch and clockmaking nation emerged. Dating to 1845, it was marine chronometer no. 2388 manufactured by Barraud, later Barraud & Lund, a now defunct English watchmaker (though a descendant of the company, Lund & Blockley, remains in operation to this day as a retailer in Mumbai). While the well-preserved state of the clock was impressive in itself, closer inspection of the movement revealed a peculiar feature. Sitting...

Petermann Bédat Introduces the 1967 Deadbeat Seconds SJX Watches
Petermann Bédat Jun 18, 2020

Petermann Bédat Introduces the 1967 Deadbeat Seconds

First revealed a year ago as a prototype with a dial that was a work in progress, the Petermann Bédat 1967 wristwatch with an unusual deadbeat seconds mechanism has just been launched in its final form. Mechanically identical to the prototype – it’s equipped a secondary escapement for the jumping seconds – the refined 1967 now has a partially-open dial that shows off the finely-finished keyless works. Initial thoughts The prototype 1967 deadbeat seconds was let down by an uninspiring faux-classical dial, which was a shame, because the movement was executed to an impressively high level. Fortunately, Messrs Petermann and Bedat embarked on a total redesign of the dial. Independent watchmakers don’t often make drastic changes to designs in response to criticism, but the two did so, and the result is a success. The new 1967 is a handsome watch that manages to look modern while evoking classical dial design. In fact, the new dial is essentially a “sector” dial with a sapphire chapter ring, a novel combination that has not been done before. And it is matched with Petermann Bédat’s take on classical lance-shaped hands, which complete the contemporary feel. The new 1967 in rose gold. Photo – Petermann Bédat Dial aside, the rest of the watch is largely identical to the prototype. The movement was already excellent and will be almost unchanged in the production versions, although Mr Petermann says that the engraved lettering on the three-quarter plate will be im...

Ulysse Nardin Freak X Silicium Marquetry Jun 10, 2020

Up Close: Ulysse Nardin Freak X Silicium Marquetry

Revolutionary for its construction and use of silicon, the Ulysse Nardin Freak is still a unique watch almost two decades after its introduction. And the full-featured Freak is still a relatively costly watch, until the Freak X came along last year. The most affordable version of a watch that helped kickstart the age of high-tech mechanical watchmaking, the Freak X retains the essence of its bigger brother while simplifying the rest of the movement. Several iterations of the Freak X have been rolled out since then, including one that ironically takes silicon out of the movement – the Freak X Silicium Marquetry. The watch has a dial decorated with inlaid tiles of iridescent silicon, using the material for its aesthetic potential, rather than the usual functional purposes in the escapement. The Freak X Silicium Marquetry Initial thoughts The Freak X Silicium Marquetry is an aesthetic variant of the standard model, so it’s identical in all respects except the dial finish. A combination of metallic and glassy, the silicon dial is different from any other dial material and suits the look of the watch well. That means the case is compact, so it wears quite well. And more importantly, the watch has a cutting-edge balance wheel amounted on the minute hand, making one revolution an hour. It’s a surprisingly advanced regulator in a watch at this price point, and probably the most advanced of all watches in the price segment. But the Freak X Silicium Marquetry is substantiall...

F.P. Journe Introduces Apr 28, 2020

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 SJX Watches
Mar 30, 2020

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 SJX Watches
Breguet Introduces Mar 21, 2020

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...

Ulysse Nardin Diver X Cape Horn Feb 25, 2020

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...

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.
