F.P. Journe Chronomètre à Résonance 20th Anniversary Featuring One Mainspring, One Differential, Two Geartrains, And Two Remontoire d’Egalité Escapements

Launched in 2000, the Chronomètre à Résonance was the first wristwatch with a resonance mechanism and it catapulted F.P. Journe into the major leagues. This latest model in celebration of its 20th anniversary is an entirely new piece based on the resonance phenomenon that now incorporates a larger single mainspring (the original had two mainsprings) with a differential driving the two going trains and a pair of remontoire d’égalité escapements.

Insight: The Science of Gear Tooth Profiles

Having explored several concepts related to energy systems in watchmaking, from mainspring barrel capacity to automatic winding and the chain and fusee, our technical series continues with a detailed examination of how that energy reaches the escapement. A vital part of all watch movements, gears are usually taken for granted and generally not given much thought. But upon closer look, gear tooth profiles vary in shape and size. These seemingly minor variations have big implications and reveal various calculated trade-offs. We take a closer look at the different gear profiles used in watchmaking and review their particularities and evolutions over time.  History and curves Mechanical timekeeping is inextricably linked to the concept of gears and transmissions. Long before the invention of the hairspring, early craftsmen and horologists were already using toothed wheels in conjunction with weights, verge escapements, and pendulums to measure the passage of time.  Historically, gear-cutters were separate professionals who catered to clock makers. Horological lore has it that the tooth profiles used during the 1600s were traced after the thumb’s shape, although it’s difficult find evidence for this theory. The invention of the hairspring marked a step-change in the technical evolution of the watch, and the later development of detached escapements enhanced precision further. These advances revealed transmission problems that had previously been masked by larger timing er...

Happenings: Roger W. Smith OBE To Lecture At The Horological Society Of New York

At the June 2026 lecture of the Horological Society of New York (HSNY), independent watchmaker Roger W. Smith OBE will trace the remarkable story of the co-axial escapement from George Daniels' original invention in the early 1970s through to its continuing modern evolution. Beginning with Daniels' determination to address the fundamental limitations of the Swiss lever escapement, the talk explores the development of his early experimental pocket watches, together with the long and often difficult process of persuading a skeptical Swiss watch industry to adopt an entirely new escapement system. Drawing on firsthand experience working alongside Daniels during the Millennium Watch project and the launch of the first Omega co-axial wristwatch in 1999, Smith will provide a rare personal insight into a pivotal moment in modern horological history. The second half of the presentation will examine the subsequent technical evolution of the escapement from 2005 onwards, including the development of the single-wheel co-axial and the changing philosophy behind escapement design — moving beyond pure chronometric performance towards long-term stability, durability, and extended service intervals.

Hands-On: Cleguer Horology Inspiration One

Mathieu Cleguer makes his debut under his own name, with the intricate Inspiration One. The relatively young movement constructor is well known in the industry but has not produced watches under his own name until now. Having worked for various movement specialists — including a stint at Akrivia — Mr Cleguer launches Cleguer Horology with a thoroughly impressive debut featuring a proprietary escapement.  Initial thoughts Although the market for artisanal time-only watches has becoming increasingly crowded, sometimes a new creation comes along that genuinely stands apart. This is the case with Cleguer Horology’s Inspiration One — a watch that that is surprisingly refined and technically imaginative for a new maker’s debut. Mathieu Cleguer is representative of a new class of independent watchmakers who are not ‘watchmakers’ in the traditional sense. Instead, he is an engineer, with the training and experience to bring fundamentally new concepts to life, so long as he can find the manufacturing partners and bench watchmakers to help realise his vision. It’s a fundamentally different background than what we’re used to seeing — George Daniels, Kari Voutilainen, and François-Paul Journe started their careers doing hands-on restoration work long before they designed movements of their own. But times have changed, and the emergence of engineer-led brands is a new trend made possible by the depth of the supplier network in Switzerland. For the visual design of...

Laurent Ferrier’s Sport Traveller is Ready for Takeoff

Laurent Ferrier’s Sport Traveller is a meaningful addition to its collection of sport watches. While the brand’s convenient push-button dual-time complication is not new, it has never been available in the go-anywhere, do-anything format of the Sport line - where it arguably makes the most sense. It’s also the first time this travel complication has been paired with one of the brand’s lever escapement movements, a change that should provide the resilience against shocks that one expects from a sport watch. Initial thoughts The sport has proven to be one of Laurent Ferrier’s most popular watches, introducing the brand to a wider audience by combining sports watch ruggedness with the high-horology independent watchmaking that the brand has become famous for. In this sense, the Sport Traveller is similar in philosophy to other luxury sport watches. That said, few manage to elevate the concept quite as high as Laurent Ferrier. The A. Lange & Söhne Odysseus and F.P. Journe Octa Sport Titanium are natural peers, as is the Patek Philippe 5164, but only the latter offers a travel time complication. The Sport Traveller is made from grade 5 titanium for a featherweight wrist presence, and debuts in what is likely to be a popular grey-on-grey colourway. Even the Sport Traveller dial text is grey, blending in with the dial to help keep the clutter to a minimum. The cal. LF275.01 continues the monochromatic look with grey-coated bridges and a solid platinum oscillating wei...

The 9 Most Accurate Watches for the Precision-Obsessed

Fundamentally, mechanical and quartz movements do the same thing: they both tell thetime. But the ways in which they both do it couldn’t be more different. Not to get into acomparison guide here, but in a nutshell: a mechanical watch is powered by a mainspringthat’s either wound by hand or automatically through wrist movement. Energy is releasedthrough a complex system of gears, an escapement, and a balance wheel that beats steadily back and forth. There’s no battery, just centuries-old engineering refined to an art form. These watches aren’t the most accurate, but accuracy isn’t really the point. Craftsmanship, tradition, and the emotional connection are. Quartz watches, on the other hand, are powered by a battery and use an electrical current to make a quartz crystal vibrate at 32,768 times per second. That vibration is incredibly stable, which is why quartz watches are vastly more accurate and require far less maintenance. They’re practical, reliable, and often more durable for everyday use, as well as being notably more affordable. Neither system is inherently “better,” though. Mechanical watches speak to passion and heritage, while quartz prioritizes precision and convenience. Ultimately, it’s less about the movement inside and more about what you want your watch to represent on your wrist. [toc-section heading="Next-Level Accuracy"] Some watches measure accuracy in seconds per day, others by seconds per month. Butthere also exists a small group of t...

Best of 2025: Surprises and Unexpected Developments

From one-off artistic creations to new escapement technologies, 2025 delivered more than its share of surprises and unexpected developments. Brands with institutional research and development departments led the way with unexpected material breakthroughs, while Geneva’s oldest watchmaker surprised (and delighted) with a clock of astronomical proportions. Rolex Land-Dweller and Dynapulse Escapement - SJX Given its institutional nature, Rolex rarely surprises, but when it does, the brand does so in a big way. The Land-Dweller was unquestionably one of the biggest debuts from Rolex in a long time. The integrated bracelet design is certainly a departure from the prevailing house style, but the Land-Dweller is a landmark mainly for the movement inside, the cal. 7135 that boasts the Dynapulse escapement. While Rolex movements have enjoyed largely incremental improvements for years, the cal. 7135 in the Land-Dweller is a radical break because it’s an all-new movement with an all-new escapement. The Dynapulse escapement is one of the most forward-thinking inventions by Rolex, arguably ever. A double-wheel, detached and indirect-tangential impulse escapement, the Dynapulse is arguably among the most advanced escapements on the market today – and the cal. 7135 is probably the most precise self-winding movement on the market. More crucially, it is being produced at scale. A new escapement is an achievement, but a new escapement manufactured in large numbers is a bona fide fea...

Omega Co-Axial Movement Explained: A Radical Invention

What is a Co-Axial Movement? More specifically, what is the now-famous Co-Axial Escapement that has become a standard feature on most all Omega watches? In short, it's both a radical concept by one of the modern era's most revered watchmaking geniuses and the culmination of a Swiss watch brand's longtime dedication to improving watchmaking accuracy. Here is the story of Omega's co-axial movements.  [toc-section heading="Early Omega Movements"]  While it is best known these days for its signature watch models, like the Speedmaster “Moonwatch” and the James Bond-worn Seamaster, Omega has also been a pioneer in movement-making since nearly the beginning. The company was founded in 1848 by 23-year-old watchmaker Louis Brandt (with family, above) in the Swiss village of La Chaux-de-Fonds. Originally called La Genérale Watch Company, and eventually renamed Louis Brandt et Fils after Brandt’s sons joined the business, it originally produced key-wound pocket watches from parts supplied by local artisans, After the growing company moved from La Chaux-de-Fonds to the more bustling town of Bienne, in the Swiss Canton of Bern, it pioneered a series of industrial watchmaking techniques and also began making its own in-house movements. The first one, called the Labrador, launched in 1885 in a now-legendary series of pocket watches. Nearly a decade later, in 1894, came the company’s chef d’oeuvre, the 19-ligne Omega Caliber, which was notable at the time for its enviable acc...
