The aesthetics of the F.P.Journe Chronomètre à Résonance’s movement is a natural consequence and reflection of the movement’s mechanical achievements. . An appearance of near total symmetry mirrors the movement’s natural harmonization of two geartrains; their balance wheels synchronizing oscillations by the natural acoustic phenomenon of resonance, without a mechanical link between them. . Caliber 1520 runs off one single barrel which delivers power to both geartrains, split equally by a differential. Each geartrain features its own unique Remontoir d’Égalité, controlling the flow of energy to the escapement, ensuring it remains constant and linear throughout the first 28 hours of the watch’s total 42 hours of power. . When in a state of resonance, the balance wheels beat naturally in opposition. If one accelerates in one direction, the other will pull it back to sync. . When worn, this horological masterpiece achieves unrivalled chronometric precision, negating the effects of a wrist’s motions. . #fpjourne #fpjourneofficial #chronometrearesonance #resonance #watches #watchmaking #horology
