Chronomètre à Resonance
Utilizing the natural resonance phenomenon, this exceptional movement revolutionized the classic standards of watch-making. Each of the two balances alternately serves as exciter and resonator. When the two balances are in motion, they enter into sympathy due to the effect of resonance and begin naturally beating in opposition. The two balances thus rest against each other, giving more inertia to their movement. Nonetheless, this harmony is possible only if the difference in frequency between them does not exceed five seconds per day of cumulated difference in six situations. Adjusting them is an extremely delicate task.
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.
