Longines Debuts the First Non-Limited Spirit Zulu Time in Titanium

Longines has been experiencing significant success in the enthusiast space since their pilot-style Spirit line of watches launched. Over the last few years, they have introduced 39mm variants and a GMT version called the Spirit Zulu Time. Zulu time is a military term that refers to Universal Time Coordinated (UTC). These timepieces, also known as GMT watches, can show a second time zone using a third hand and a 24-hour scale on the dial. In December 2023, Longines partnered with Hodinkee to produce a special version of the Zulu Time in grade 5 titanium, featuring a 39mm case and limited to only 500 pieces worldwide. This special edition bore a striking resemblance to another brand’s popular GMT watch but was significantly thinner and much less slab-sided, which appealed to many collectors. As successful as that model was, Longines did step away from the original charm of the Spirit collection, leaving enthusiasts wanting a grade 5 Titanium GMT watch that was not a limited edition. They have heard the call and have just announced a new 39mm Spirit Zulu Time in this material, which fits right in with all the others in the lineup. Why are we explicitly mentioning the titanium grade used in these watches? In wristwatches, there are generally two types of titanium used. Grade 2 and grade 5, and while they both have the key qualities that make the material special (they are both very light), there is a tangible difference. Grade 2 titanium is commercially pure titanium, which ...

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…)

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...
