The Watch for Action Heroes: Panerai Luminor Submersible 1950 Amagnetic

We don’t think about magnetic fields often and though they are thoroughly pervasive in our high technology environments, we tend to think of magnets as these little buttons of fun used to “hover and drag” metal cars across table tops. It’s time we grow out of childish notions and understand that magnetic fields are generated […]

Only Watch 2021: Atelier de Chronométrie AdC21

Founded to give new life to vintage chronometer movements and resurrect old-school designs, Atelier de Chronométrie (AdC) has completed only a few watches to date, but has quickly become known for wristwatches that are elegantly refined inside and out. In its inaugural outing at Only Watch, the watchmaker put together the AdC21, a time-only watch that is simple but executed with lavish detail, and dressed in a nostalgic, “pink on pink” livery. Like AdC’s other creations, the AdC21 is powered by a movement that started life as a vintage ébauche before being upgraded with parts fabricated by hand in-house. And the movement has been finished to level far beyond what the vintage calibre ever was. Initial thoughts AdC watches are intrinsically appealing to enthusiasts who favour old-school dress watches, which often have discreet, refined details that are uncommon in contemporary watches. One of the brand’s cofounders is a vintage watch dealer whose eye and experience explain the house style. At the same time, AdC elevates the design with the artisanal quality of the case and movement, most of which are made in house. The AdC21 is arguably the best time-only watch the brand has created to date. Entirely classical yet novel, the dial has a two-tone finish matched with an unusual interpretation of the “scientific” dial. And the case is also more elaborately constructed than those found on AdC’s earlier works. Beyond the design and craft, the shades of pink that d...

Introducing: Two New Gérald Genta Geneva Time Only Grafite And Marrone Watches In White And Pink Gold

Since I moved to Geneva last May, I started trying to figure out what the city is all about. I had been visiting the lakeside town for probably 20 years, but a visitor doesn’t get to experience what a resident encounters daily. It’s hard to define Geneva. Yes, banks, watchmakers, and international organizations, such as […] Visit Introducing: Two New Gérald Genta Geneva Time Only Grafite And Marrone Watches In White And Pink Gold to read the full article.

Why I Bought It: Rexhep Rexhepi/Akrivia Chronomètre Contemporain

There are nice-looking watches, there are crisp-looking watches, and then there are watches that emanate an otherworldly glow. For GaryG the Rexhep Rexhepi/Akrivia Chronomètre Contemporain falls into the third category, so much so that it became a running joke for a friend to pantomime a “smelling salts” motion as a signal for Gary to pull up his sleeve and jolt him back to attention. Here he explains why he bought this new classic watch.

Up Close: Rexhep Rexhepi Chronomètre Antimagnétique “Only Watch”

The two most important examples of independent watchmaking in Only Watch 2024 are arguably the stealthy F.P. Journe Chronomètre Furtif Bleu and the Rexhep Rexhepi Chronomètre Antimagnétique, each a significant creation of a leading watchmaker of his generation (and interesting enough, both are sports watches). Inspired by mid-20th century explorer’s watches that were magnetism-resistant, the Chronomètre Antimagnétique (RRCA) is an elegant but robust watch with a stainless steel case and an entirely new calibre equipped with an indirectly-driven centre seconds with a hacking, zero-reset mechanism. In its Only Watch form, the RRCA is a unique watch but also a prototype for a new line of elegant sports watches. NB: The watch pictured is a work in progress that is not entirely finished so the dial is a prototype and the movement is not perfectly clean. It will be delivered in a perfect state to the eventual owner. Initial thoughts Many of the RRCA’s details bring to mind mid-20th century “sports” watches. Not the sports watches we know of today, but rather the water-resistant Patek Philippe watches made in the 1940s and 1950s for gentlemen sportsmen and adventurers. This reflects with Rexhep Rexhepi’s respect for traditional Geneva watchmaking, which is also expressed in the RRCC but in a different manner. The RRCA subtly marks a new direction for Rexhep Rexhepi’s aesthetics. It’s clearly a thoughtful evolution of the RRCC. While the RRCC is a dress watch, ...

Hands On: Rexhep Rexhepi Chronomètre Contemporain II Diamant

Much lauded at its launch last year, the Rexhep Rexhepi Chronomètre Contemporain II (RRCC II) was originally available only in two guises of rose gold or platinum, each with a matching enamel now. Now Rexhep Rexhepi has quietly debuted a small run of the RRCC II in the same metals with gemstone hour markers to match. The platinum version features a black enamel dial with baguette-cut diamond indices that give it a stark, formal beauty. And the rose gold model has a cream enamel dial with ruby markers. Initial thoughts Discreetly glamorous gentlemen’s watches with diamond hour markers are a well established tradition in watchmaking, particularly so during the mid-20th century at high-end brands like Patek Philippe and Audemars Piguet. The new RRCC II is clearly a reference to such historical watches. Despite being a modern watch, and clearly recognisable as such, the diamond-set RRCC II manages to capture the subtle, elegant nature of its historical inspiration thanks to its compact case with graceful lugs inspired by vintage Patek Philippe models, including this ref. 2551. A possibly unique Patek Philippe ref. 2551 dating from 1957 with a white gold case and diamond indices that sold for almost CHF360,000 at Phillips in 2022 Interestingly, even though the RRCC II was not originally conceived as a gem-set watch, the dial accommodates the diamond hour markers perfectly. The glossy surface of the enamel dial complements the diamonds’ sparkle, while the alternating track ...
