Introducing: Two New Versions Of The Blancpain Fifty Fathoms Bathyscaphe In Grail-worthy Gold

The Fifty Fathoms family from Blancpain has already crossed the line from tool watch into wrist grails for most of us. This was already a fact with rising prices years ago and symbolizes for many the change in how we perceive wristwear. By nature they are all instruments to tell the time, and any reference […] Visit Introducing: Two New Versions Of The Blancpain Fifty Fathoms Bathyscaphe In Grail-worthy Gold to read the full article.

Insight: The Geometric Efficiency of Escapements SJX Watches

Insight: The Geometric Efficiency of Escapements

Mechanical escapements remain the most fascinating and enticing field of horological study even in the 21st century. At its core, an escapement has a simple purpose: restore lost energy to the oscillating organ while regulating the discharge speed of the going train – thus allowing for time measurement. Straightforward as the concept is, executing an escapement well is a completely different affair. The escapement is perhaps the element of the mechanical movement that has undergone the most iterations since its invention. The reason is simple: escapements were, and remain, imperfect systems. In fact, the escapement is often the least efficient aspect of a mechanical movement in terms of energy transfer. That’s why watchmakers and engineers have devised innumerable variants in the search of the ideal escapement.  Explaining escapement efficiency In physics the efficiency of a system is the proportion of useful work done relative to the total work done by said system. The result, measured as a percentage, speaks to the energy conserved within the system. For example, an 80% efficiency means that 20% of the total available energy is lost, with the remaining 80% usefully conserved.  That said, an efficient escapement isn’t necessarily chronometrically-potent, since there are more criteria, apart from energy conservation, which reflect in a movement’s accuracy. The way in which escapement parts impulse to the balance, the proximity of the equilibrium point and the deg...

Time Through the Ages, Part 4: The Waltham Watch Company – A Seismic Disruption in Time

Editor’s Note: Time Through the Ages is a four part series written by Andrew Canter, member of the British Horological Institute, Alliance of British Watch & Clock Makers, and the British Watch & Clock Makers Guild. In this fourth and final installment of the series, Andrew examines the dramatic leap forward in watch manufacturing made by the Waltham Watch Company, and how the Swiss watch industry responded. For more from Andrew, check out his work at Mr. WatchMaster.  “Had the Philadelphia Exhibition taken place five years later, we should have been totally annihilated without knowing whence or how we received the terrible blow. We have believed ourselves masters of the situation, when we really have been on a volcano.”  Edouard Favre-Perret, Swiss Member of the International Jury Have you ever heard of Jacques David or Theophilus (Théodore) Gribi? How about Ambrose Webster? They were the key protagonists in the fascinating story of the rise of American watchmaking and subsequent potential demise of Swiss watchmaking. It’s a story of industrial espionage and spying that changed the course of the global watch industry forever. The Centennial Exhibition of 1876 took place in Philadelphia and was the first official World’s Fair to be held in the United States, celebrating the 100th anniversary of the signing of the Declaration of Independence in Philadelphia. Almost 10 million visitors attended the exposition, with 37 countries participating. Centennial Exhibiti...

Our Favorite Releases of the Year (So Far…) Worn & Wound

Our Favorite Releases of the Year (So Far…)

Well, we’re a little more than halfway through 2024, so we thought it would be a good time to ask our contributors about their favorite watches of the year to this point. It’s been, to put it mildly, a strange year. Coming off 2023, a watch release year that saw an almost never ending string of hits, 2024 seems a bit more sedate. But the highs, as they say, have been high, and there are specific sectors of the watch world that seem to be thriving with creativity and pushing serious boundaries.  The selections here from our staff and contributors run the gamut, as always, from large brands to small, affordable to luxury. We’d love to hear from you: let us know what your favorite releases of 2024 are in the comments below.  Zach Weiss – Sinn U50 HYDRO I had a bit of a hard time picking a watch for the topic, and to be honest, it’s because I haven’t been overly blown away by anything yet this year. Not that they’ve been bad; there just hasn’t been much that has really tempted me personally. That’s probably a good thing, but, as I pondered releases, one watch eventually stood out: the Sinn U50 Hydro. The Sinn U50 line was already a great success for the brand, bringing their distinctly modern, tool watch language to a manageably-sized dive watch. But, this year when they added their HYDRO technology to the package, it made it a watch that truly could only be a Sinn, and likely appreciated by only devoted Sinn enthusiasts. For those unaware, Sinn’s HYDRO w...

Insight: Governors of Minute Repeaters, Sonneries, and Other Striking Watches

Repeaters are one of the most complicated mechanisms in watches and over the years the complication has been refined by successive generations of watchmakers. Now, perhaps more than ever, watchmakers dedicate absolute attention to perfecting the quality, speed, accuracy, and durability of the striking works. Various components are required to chime the tunes of time with hammers and gongs. Paradoxically, amongst the most crucial parts of a chiming watch are those that work quietly, or silently, in the background – the governor. One of the most recent new repeater calibres, the A. Lange & Söhne Richard Lange Minute Repeater What is a governor? The governor regulates the speed of the striking pattern, in other words the pace of the individual chimes. A repeater movement contains a separate gear train for the repeating works, which are powered by their own smaller, auxiliary spring. The last component of this train consists of the governor. The governor’s task is to introduce resistance in the repeater train, allowing it to be regulated. Therefore, less resistance accelerates the striking speed, while more resistance slows down the repeater chimes. The Vacheron Constantin cal. 1731 with the secondary spring visible between the hammers The fine-tuning of the repeater’s speed is prized as an essential factor in ensuring a perfect series of chimes. If the pace is too fast, the vibrations of the gongs produce jarring overtones that cancel each other out. If too slow, not o...

Christopher Ward Launches a New 38mm Version of The Twelve with the “Ice Cream Collection”

In recent years, the Windup Watch Fair has played host to a number of notable debuts from some of our favorite watch brands. It’s a great time to launch a watch, after all. With hordes of watch enthusiasts descending on Chicago’s Venue West over the weekend, brands had a captive audience to launch splashy new releases. Christopher Ward, a Windup mainstay for years, keenly understands this, and jumped at the chance this weekend to debut colorful new versions of The Twelve in a new 38mm case size. The enthusiast favorite size rounds out a varied collection of integrated bracelet sports watches that have driven a lot of interest in the brand since they launched a little over a year ago, and Christopher Ward, as always, is having some fun with color in this new batch.  The brand has dubbed these the “Ice Cream Collection” for their bright colors, all of which are inspired by ice cream and thus feel perfectly timed as a summer watch release. The new, cleverly named colors are Biel-Berry, Mint 38, Peach Sellita, and Made in Mangohead. They all feature the now familiar Christopher Ward flag motif repeated across the dial, and come on integrated stainless steel bracelets as well as color matched rubber straps. We had a chance to see these in the metal in Chicago over the weekend, and, pardon the cliche watch writer terminology, the colors really do pop. My personal favorite is easily the Peach dial, but talking to fair attendees over the weekend it was clear that all of t...
