F.P.Journe Chronomètre à Resonance

F.P.Journe offers a new face to the renowned Chronomètre a Résonance, acclaimed by collectors and professionals of the brand worldwide.

In an ultimate quest for precision, the dial at 9h now offers a time indication of 24 hours, defining precisely the hours of day and those of night. The dial at 3h in silver guilloche indicates the local time but can also be used for the same time zone.

Hardly a small modification for the subtle 18K rose gold mechanism with its two perfectly synchronised beating mechanical hearts that are revealed through a sapphire crystal case-back: there is now a different gear transmission making the hands turn in 24 hours instead of 12 hours.

The new Chronomètre a Résonance will be, as its predecessor was, available in two versions: one with a platinum case and white gold dial and the other all in red gold. The two dials in silver guilloche indicating the hours, minutes and seconds are secured on the 18K gold dial by polished steel rings, a patent by F.P.Journe.

The New Chronomètre a Résonance is imbued with a profoundly poetic depth, and remains, 10 years later, the most precise mechanical watch of contemporary watch making.
