New: Panerai Submersible Marina Militare PAM01697 & PAM01698 Carbotech™

Panerai’s Submersible Marina Militare PAM01697 and PAM01698 are tactical evolutions of the brand’s dive watch lineage, paying tribute to the Italian Navy’s aviation division (Aviazione Navale). Both models feature green-grained dials, radar-style subdials, and engraved casebacks, but diverge in material execution-one in brushed steel, the other in Panerai’s proprietary Carbotech™.

Hands On: F.P. Journe Chronomètre Souverain 20th Anniversary

Although Francois-Paul Journe is best known for his inventions like the Tourbillon Remontoir d’Egalite and Resonance, not to mention the whole suite of Octa models, the Chronomètre Souverain was also arguably one of his brand’s foundational models. This year F.P. Journe is marking two decades of the watch with the Chronomètre Souverain 20th Anniversary, which is essentially the original in new dress – the dial is now dark blue with applied gold numerals. Initial thoughts When the Chronomètre Souverain debuted in 2005 – the same year as the Breguet Tradition that was recently revived – it was novel and exciting; I remember the buzz amongst enthusiasts then. The F.P. Journe brand was barely six years old. The Chronomètre Souverain was then one of the rare few time-only watches from an independent watchmaker, and it had an all-new movement to boot. Today it is less exciting for sure, but the movement remains surprising novel for a basic calibre. As an entry-level watch, the Chronomètre Souverain remains excellent (even if availability is an obstacle). Although the Chronomètre Souverain is the simplest mechanical F.P. Journe watch, the cal. 1304 inside still retains the technical hallmarks of the brand, namely elegant, concise engineering and symmetry. Clever touches include the “invisible” gear train; only the regulator and barrels are visible on the main plate. From its conception, the cal. 1304 was conceived for chronometry. The utility and strength of t...

Hands On: F.P. Journe Chronomètre Furtif

After teasing collectors with the compact Chronomètre Furtif Bleu in 2023, F.P. Journe has unveiled its successor, the Chronomètre Furtif (CF). The CF offers the same dimensions as its predecessor as well as a similar laser-engraved grand feu enamel dial, but takes the idea of furtif, or “stealthy”, even further with black-on-black livery. While the CF Bleu was a one-off piece in tantalum made for the Only Watch charity auction where it sold for CHF2 million, the new CF is a regular production model crafted almost entirely from scratch-resistant tungsten carbide. Initial thoughts The CF is a watch that hits you over the head with its intense darkness and exceptional weight. It’s not dark in the same way as an H. Moser & Cie. Venturer Vantablack, which effectively absorbs light; rather, the dial is a deep glossy black like the glass of an iPhone screen. This reflectivity makes it difficult to photograph but easy to enjoy. These characteristics are thanks to the flawless black grand feu enamel dial and laser-engraved markings. Because of the way the light plays across the dial, it looks slightly different from almost every angle. It’s a dramatic and interactive dial that contributes significantly to the overall wearing experience. The CF is a true heavyweight, tipping the scales at 250 g. But it feels even heavier on account of its wearable 42 mm footprint and slim 9.55 mm thickness. This size-to-weight ratio gives it an almost overwhelming sense of density. The wa...

First Look – The New Platinum Editions of the Ferdinand Berthoud Chronomètre FB3 SPC

In 2015, one of the great names in 18th-century watchmaking was resurrected by Chopard’s co-president Karl-Friedrich Scheufele. Ferdinand Berthoud (1727-1807), the Swiss horologist who emigrated to Paris in 1745 and gained fame for his marine chronometers, was granted a second lease of life. Determined to perpetuate the legacy and chronometric credentials of F. Berthoud’s past […]

F.P. Journe Chronomètre Optimum Black Label Reviewed by Tim Mosso

Technically, this F.P. Journe watch is called the “Chronomètre Optimum Black Label,” but it should be called the “Ultimate.” That’s how much Tim Mosso reveres and admires a timepiece Journe himself describes as the most accurate mechanical watch he knows how to construct.

Up Close: F.P. Journe Chronomètre Furtif Bleu “Only Watch 2024”

Possibly the successor to the Chronomètre Bleu, the Chronomètre Furtif Bleu is a unique creation made for Only Watch 2024 taking place on May 10, but also the template for a next generation of lineSport watches. The Furtif Bleu retains the familiar silhouette of the lineSport, but is executed entirely in tantalum – notably the bracelet is tantalum – with a fired enamel dial. Additionally, it is equipped with a new calibre that displays the power reserve and moon phase on the back. Initial thoughts Despite its name and low-key colours, the Furtif Bleu is a very striking watch, largely because of the contrast between the dark grey tantalum and the blue dial with an orange seconds hand. In the hand, it is heavy, as expected for the metal, and also silky in feel due to the finely blasted surfaces of the case and bracelet. Close your eyes and it feels like the current lineSport in platinum, though the blasted finish is finer than that on the existing gold and platinum models. And on the wrist, it is unexpectedly elegant for a sports watch because of its height, which is just 9.5 mm. That’s slightly thicker than the Chronomètre Bleu and noticeably thinner than the lineSport Automatique Reserve. One of the most notable aspects of the watch is the bracelet, which is entirely tantalum. The nature of the alloy makes it particularly difficult to work, explaining the cost and rarity of tantalum watch cases. Tantalum bracelets are even less common. The only other brand I can t...

Launched in 2000, the Chronomètre à Résonance was the first wristwatch with a resonance mechanism and it catapulted F.P. Journe into the major leagues. This latest model in celebration of its 20th anniversary is an entirely new piece based on the resonance phenomenon that now incorporates a larger single mainspring (the original had two mainsprings) with a differential driving the two going trains and a pair of remontoire d’égalité escapements.

Review: Montblanc Heritage Chronométrie Collection Twincounter Date

Montblanc released the Heritage Chronométrie Collection Twincounter Date at SIHH 2016. This watch spiked our attention because of its utilitarian design and understated beauty. It stands out from the usual time and date wristwatch primarily because of its reinterpreted dial. While not excruciatingly obvious, the unusual subdial positioning of the seconds counter juxtaposed with a larger date subdial is what makes this watch so exciting to us.
