Our Predictions In The Chronometry Category Of The 2019 Grand Prix d’Horlogerie de Genève (GPHG): Is This Really About Precision?

The Grand Prix d'Horlogerie de Genève's 2019 Chronometry category awards mechanical watches comprising at least one tourbillon and/or a special escapement and/or another development improving chronometry (precision timekeeping). Our panel clearly wishes that there were more empirical evidence for the claims of high precision and is split on the winner. What's your favorite?

Introducing the Akrivia Rexhep Rexhepi Chronomètre Contemporain “Only Watch” SJX Watches
Patek Philippe Star Calibre 2000 pocket Jul 1, 2019

Introducing the Akrivia Rexhep Rexhepi Chronomètre Contemporain “Only Watch”

Akrivia’s entry for Only Watch 2019 is a unique variant of its critically acclaimed Chronomètre Contemporain but with an added bonus – the platinum case is made by storied case specialist Jean-Pierre Hagmann. The first outing at Only Watch for Akrivia and its founder Rexhep Rexhepi, the unique Chronomètre Contemporain is equipped with a dial made of grey-blue fired enamel featuring white enamel markings. But the dial is unusual for having a hand-hammered finish, a decoration typically only applied to gold dials, giving it a granular surface. The view from the back of the 38mm platinum case is identical to that of the standard model, save for the “JHP” hallmark on the lower right lug. It’s short for Jean-Pierre Hagmann, a semiretired case maker who was responsible for some of the most exquisite watch cases of the 1980s and 1990s. Amongst his work is the incredibly complex case of the Patek Philippe Star Calibre 2000 pocket watch. The Chronomètre Contemporain “Only Watch” is the first watch to emerge from the recently inked collaboration between Akrivia and Mr Hagmann. Stay tuned for more on this. The Chronomètre Contemporain “Only Watch” has an estimate of 40,000-60,000 Swiss francs, and will go under the hammer on November 9, 2019 at Christie’s in Geneva.  The complete Only Watch 2019 collection can be seen on onlywatch.com.

VIDEO: The heart of Panerai - the new Luminor Marina Logo 3 Days in steel 

The heart of Panerai’s line-up has to be the entry-level Luminor. A 44mm watch with the classic crown guard-equipped Luminor case and not much in the way of frills. White or black dial, white logo or blue, small seconds or not, and a range of strap options. That’s pretty much it. But you know what? … ContinuedThe post VIDEO: The heart of Panerai – the new Luminor Marina Logo 3 Days in steel  appeared first on Time+Tide Watches.

IN-DEPTH: The Heritage Chronométrie Annual Calendar Chronograph proves that the secret to Montblanc’s success is complicated

The story in a second: Montblanc’s 2016 Heritage Chronométrie highlight is a complicated number, packed with value. Jerome Lambert descended, whirlwind-like, on Montblanc in 2013. His presence was felt immediately, as the global luxury giant began turning out increasingly impressive timepieces, many with a complicated, heritage bent. Then, as suddenly as he had arrived he was gone, … ContinuedThe post IN-DEPTH: The Heritage Chronométrie Annual Calendar Chronograph proves that the secret to Montblanc’s success is complicated appeared first on Time+Tide Watches.

Montblanc Heritage Chronométrie Ultra Slim Jun 26, 2015

Review: Montblanc Heritage Chronométrie Ultra Slim

Montblanc is definitely riding the high wind with its new line up. They are challenging prices within the industry and are indeed making the news. Like with this ultra slim, we thought it was executed exceedingly well and serves its intended purpose. The only qualm that we have with it, is its uncanny similarity to Jaeger LeCoultre's Master Compressor collection.

How marine chronometers shaped horology today

Navigation is definitely taken for granted these days. Not that I don’t personally rely on Google Maps to take me pretty much everywhere, but the art of traversing the globe was one of the most difficult, frightening, and often heroic skills for thousands of years in human history. As if finding your way through icy … ContinuedThe post How marine chronometers shaped horology today appeared first on Time+Tide Watches.

Introducing the Zenith G.F.J., a Chronometry Focused Tribute to the Brand’s Founder Worn & Wound

Introducing the Zenith G.F.J., a Chronometry Focused Tribute to the Brand’s Founder

Last year, I had the privilege of sitting down with Benoit de Clerck to talk about all things Zenith. At the time, Benoit was just a few short months into his tenure as CEO of Zenith, and Watches & Wonders was only barely in the rearview, but de Clerck made it very clear that he was already looking ahead, not just generally, but towards something very specific, and very exciting. “I’m working hard on something new next year, which - obviously - I like, because it’s very unique, and we’re producing very small quantities and all that. And, I can’t tell you much more, but next year we’re celebrating our 160th year and we will come up with something that the collectors will be very, very, very happy with.” Well, now, nearly a year later, we know what that “something new” is, and de Clerck was absolutely right - because it is something to be very, very happy with. I’m talking, of course, about the new Zenith G.F.J. G.F.J., in this case, stands for Georges Favre-Jacot, the name of the man who founded Zenith some 160 years ago, but it might as well stand for ‘Great F***ing Job’ because Zenith has knocked it out of the park with this one. At the heart of the G.F.J. is a revived version of the calibre 135, a historically significant and long-dormant movement, designed by Ephrem Jobin in the years after World War II and produced from 1949 to 1962. The Calibre 135 was widely used by Zenith at that time, but especially prized is the 135-O variant created...
