The F.P.Journe Chronomètre à Résonance features two subdials that can be independently set via the crown at 2 o’clock. The subdial on the left displays a 24-hour display, allowing the timepiece to be set to two different time zones, if the wearer chooses. . The crown at 4 o’clock will reset the seconds hands simultaneously once pulled, after which the hands will run in sync portraying the adaptation of the natural phenomenon of resonance. . Peeking through a center cutout on the dial, the differential equally splits energy from the single barrel to the two geartrains. . 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. . Seen is the F.P.Journe Chronomètre à Résonance in Platinum with an 18K white Gold dial. . #fpjourne #fpjourneofficial #chronometrearesonance #resonance #watches #watchmaking #horology
