F.P.Journe unveils Chronomètre Furtif

Chronomètre Furtif
Ref. CF
Calibre 1522
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 - now part of the lineSport collection - has been designed by François-Paul Journe to have a 42 mm case and bracelet made from Tungsten Carbide (interspersed with Tantalum elements). Usually used for highly technical applications, it is the perfect material as, in addition to its biocompatibility and low chemical reactivity, it is highly shock-resistant and practically indestructible.

A year and a half of research and testing was needed to perfect the anthracite grey mirror-polished Grand Feu enamel on white Gold dial, with matte-finished numerals and minutes track. These are elements that only the owners of this watch will be able to see by altering the angle of the dial against the light.

Housed in a 42 mm diameter case, the 18K rose Gold Calibre 1522 with manual winding displays the hours and minutes, and the centre seconds. The white seconds hand is fitted directly onto the axis of the dedicated wheel, whose nearly linear gear train is a first for F.P.Journe. Symmetrically positioned on the back are the power reserve (56 h) indicator and the moon phases.

Reflecting the skill of our watchmakers and the talent of the artisans of Les Boîtiers de Genève and Les Cadraniers de Genève - both owned by F.P.Journe - the Chronomètre Furtif takes you back to the fundamentals: having the time for yourself alone.

After the Tourbillon Souverain, the Chronomètre à Résonance and the Octa, it is now the turn of the Chronomètre Souverain.

Introduced in 2005 and now the most sought-after model in our collections, the Chronomètre Souverain is a watch with three hands and a power reserve indicator. Apparently simple in design, but embodying great mechanical know-how, this timepiece draws its inspiration from traditional marine chronometers. In the 18th century, the governments of Great Britain and France sought to dominate the seas. The two nations offered substantial rewards in order to incite the greatest horological minds to invent a method that would allow the determination of longitude at sea. Since the safety of ships and their crews were of the utmost importance, these mechanical instruments had to be extremely precise.

The Chronomètre Souverain perpetuates this quest for chronometric excellence. Constructed in the purest horological tradition, it is animated by the 18K rose Gold Calibre 1304, which is extra-flat – only 4 mm thick – and manually wound. The two parallel-mounted barrels deliver a highly linear force to the escapement for over 56 hours.

One telling detail reveals that history: the placement of the power reserve hand on the dial at 3 o’clock is a rare occurrence in horology, for that position interferes with the time-setting mechanism operated by the crown. The choice was inspired by marine chronometers, which measured the time elapsed since the last winding. Conventional displays, however, indicate the remaining power reserve. Here that scale is reversed: it stands at “0” when the springs are fully wound and progresses as they unwind.

In order to create a slim and elegant watch, François-Paul Journe rethought the power reserve mechanism, reducing its thickness by more than half to achieve a mere 0.5 mm through the use of ceramic ball bearings, a patented innovation.

In celebration of this 20th anniversary, F.P.Journe announces the Chronomètre Souverain Collection Boutique, with two blue guilloché Silver dials, exclusively available in F.P.Journe Boutiques and Espaces.
