F.P.Journe CHRONOMÈTRE FURTIF
F.P.Journe expands the lineSport Collection by introducing the new Chronomètre Furtif model.
While the unique “Chronomètre Furtif Bleu” Only Watch 2024 piece was the first in the world to feature a Tantalum case and bracelet, the small production run of the Chronomètre Furtif has been designed by François-Paul Journe to have a 42 mm case and bracelet made from Tungsten Carbide (interspersed with Tantalum elements).
For the design of each of the elements which make up the exterior of this 42 mm timepiece, which is just 9.5 mm thick, the Manufacture was able to rely on the expertise of Les Boîtiers de Genève, a specialist entity owned by F.P.Journe.
Creating the entire exterior from Tungsten Carbide required access to the latest generation of tooling. Les Boîtiers de Genève boasts a cutting-edge machine park, used to the best of its capacities through complex and innovative processes, allowing them to push the limits of engineering in terms of machining and finishes.
The engineers and machinists working for Les Boîtiers de Genève were responsible for reworking the entire case middle. They were in charge of the sand-blasted and polished finishes. The same process obviously applied to the bracelet that these specialists developed from the model designed by the F.P.Journe Manufacture’s founder. Thanks to their mastery in working demanding metals, these ultra-specialist craftsmen have successfully overcome the challenge of designing a flat three-row link, also made entirely from Tungsten Carbide.
In order to do justice to this exceptional casing, F.P.Journe opted to bestow this new watch with a mirror-polished anthracite grey Grand Feu enamel on white Gold dial, designed in the same spirit as the one adorning the unique piece sold at the Only Watch 2024 auction.
This fired disc reflects the expertise and creativity possessed by the artists working within Les Cadraniers de Genève, a hub of expert craftsmen owned by F.P.Journe, which shares its building and cutting-edge technology with Les Boîtiers de Genève.
The new F.P.Journe CHRONOMÈTRE FURTIF watch houses the Calibre 1522, a new hand-wound mechanical movement in 18K rose Gold measuring 33.50 mm in diameter and 5.90 mm thick. Developed in-house by F.P.Journe, it displays the hours and minutes but also the central seconds thanks to a central second hand driven directly into the axis of the dedicated wheel.
This movement has an in-line gear train: a real first for F.P.Journe. With its 197 components, the Calibre 1522 has a regulating organ equipped with a 15-tooth escapement wheel, a straight-line anchor and a balance with four inertia blocks and a micro-flamed flat Anachron balance spring oscillating at 3 Hertz, or 21’600 vibrations per hour.
Placed horizontally on the 3-9 o’clock axis, in the centre of the round 18K rose Gold main plate finished in line with the highest standards of Haute Horology, it is framed by two useful indicators which complete the free space here.
At 12 o’clock sits the power reserve indicator with two barrels mounted in parallel and which, once wound, guarantee 56 hours of operation with chronometric tolerances. The crown used to wind them also allows the time to be set, and, when pulled out to the second position, it is also used to set our natural satellite which is realistically depicted in the moon phase window at 6 o’clock.
