JLC Geophysic True Second is both functional and a nod to its historical origins when a dead beat seconds hand signified high-precision mechanical watchmaking.
JLC's new Caliber 770 automatic movement has an additional gear train with a star wheel on the escapement wheel axis that powers a small dead seconds spring near the center of the rotor. Every second, the spring releases on a whip-like lever that advances the seconds hand and, instead of a smooth sweeping effect, the dead beat seconds jumps from one second to the next.
