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 SJX Watches

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...

Hands On: Ferdinand Berthoud Chronometre FB 2TV SJX Watches

Hands On: Ferdinand Berthoud Chronometre FB 2TV

Now beginning its second decade under the leadership of Chopard Co-President Karl-Friedrich Scheufele, Ferdinand Berthoud (FB) has introduced the Chronomètre FB 2TV.1, the first model in the new Mesure du Temps 1787 collection. The FB 2TV represents an evolution of the brand’s long-running chain-and-fusee architecture, adding zero-reset seconds and a flying tourbillon, and inverting the calibre to exhibit its key functional elements on the dial side. Initial thoughts It’s hard to believe that it has been ten years since the debut of Ferdinand Berthoud as a contemporary brand. It was clear from the outset that FB had big ambitions, launching its first model with a chain and fusee mechanism. Since then, FB has maintained admirably high standards for itself, and while not all of the designs appeal to me, the obvious effort that goes into every watch — each FB 2TV receives more than 300 hours of decoration — has won the brand a durable position near the top of the industry. Now beginning its second decade, FB has released the first watch in a new collection that portends a more mechanically expressive style, with features like the chain and fusee inverted to the dial side. This approach isn’t original, but the success of other ‘inverted’ movements from independents like Kari Voutilainen demonstrate demand for the format. Quirky designs Ferdinand Berthoud, an 18th-century pioneer of the spring detent escapement among other breakthroughs, approached watchmaking fr...

Breaking News: F.P. Journe Souscription Chronomètre à Résonance Achieves $13.9 Million - Becomes Fifth Most Expensive Wristwatch Ever Sold Hodinkee

Breaking News: F.P. Journe Souscription Chronomètre à Résonance Achieves $13.9 Million - Becomes Fifth Most Expensive Wristwatch Ever Sold

It felt inevitable. Just over six months after an F.P. Journe narrowly missed joining a certain historic list of wristwatches dominated by Patek Philippe and Rolex with the $10.75 million sale of Francis Ford Coppola's personal FFC at Phillips New York (a record for the brand), one finally reached that rarified air. François-Paul Journe invented it. He made it. The market made it historic. The F.P. Journe Souscription Chronomètre à Résonance no. 007 is now the fifth-most expensive wristwatch ever sold and the third-most expensive watch sold not for charity. Arguably Journe's most important and emblematic model, a confluence of details made this example—which crossed the auction block on Saturday, June 13—the one to own, at least according to bidders. To the tune of almost $14 million, no less. In some ways, it seems the perfect cap to a wild shift in the market where, in less than a year, F.P. Journe has become more closely watched than other previously preferred blue-chip brands and references. And yet, the market is so hot that there were a number of remarkable results from the New York, Geneva, and Hong Kong auctions.  Not for nothing, but a Patek Philippe 5004 is now a $5 million watch, not only blowing out the previous non-charity record ($1.5 million for Michael Ovitz's platinum example, which was sold last fall), but eclipsing the 5004T for OnlyWatch (which sold for $4 million, give or take, back in 2013). And the fresh-to-market pink gold, satin-cased Pate...

Hands On: Jaeger-LeCoultre Master Control Chronometre SJX Watches

Hands On: Jaeger-LeCoultre Master Control Chronometre

The most talked-about release from Jaeger-LeCoultre (JLC) at Watches & Wonders was the refreshed Master Control collection, which debuted on a surprising integrated bracelet. Available with or without perpetual calendar or power reserve complications, the Master Control Chronometre is powered by the latest version of the brand’s long-running cal. 899, which is now certified by both COSC and a new internal standard called the High Performance Guarantee (HPG). Initial thoughts Since the Master Control Chronometre debuted at Watches & Wonders, I have been asked multiple times whether it is a dress watch or a sport watch. Setting aside the issue of the false dichotomy that exists between these categories, the Master Control Chronometre presents itself primarily as a dress watch on a bracelet. While the bracelet’s angular facets evoke those of the Vacheron Constantin Overseas, the staid Master Control dial is what defines the look. The simple sunray finish and slim hands — not to mention the lack of any lume — firmly root the Master Control Chronometre in the dress watch category. The soft blue and brown dials are each attractive in their own right, with colour-matched date wheels to avoid any harsh transitions. While the text is arguably superfluous, the ‘Chronometre’ label is more interesting than the typical ‘Automatique’ text that mars most Master Control dials. In terms of the value proposition, it’s a tale of two metals. The stainless steel model isn’t...

Hands On: Nouvelle Chronometrie Montre Ordinaire SJX Watches

Hands On: Nouvelle Chronometrie Montre Ordinaire

One of the most intriguing debuts in independent watchmaking this year is Nouvelle Chronometrie with its Montre Ordinaire. Despite the name, Nouvelle Chronometrie is actually Japanese, and the “ordinary” watch is a tourbillon chronometer inspired by 20th century observatory chronometer watches and dressed in formal Breguet attire. With its rigorously classical design, evident on both the front and back, the Nouvelle Chronometrie is distinctly Japanese at heart in how it careful reproduces and enhances traditional watchmaking – executed with a great deal of attention to detail. Moreover, the manufacturing of the watch is a combination of both old school manual methods and modern technology, reflecting a typically Japanese embrace of technology, not for cost efficiency, but for the sake of quality. Initial thoughts I first came across Nouvelle Chronometrie on Instagram. It was just images of the watch, with no information on the brand’s origins. Then I learnt Nouvelle Chronometrie was founded and led by Noritaka Sakurai, a longtime collector who pivoted to join the industry – which ironically left me a little sceptical. Though I have known Mr Sakurai for a long time and regard him highly as a collector, he was chief executive at Hajime Asaoka’s watchmaking outfit until 2020 – that employer was a red flag for me. Fortunately, Mr Sakurai has left that behind, and has now gone all in with Nouvelle Chronometrie, a project that deserves recognition and praise. Accor...

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.
