In 1780, Antide Janvier, a gifted watchmaker and watchmaker to the King of France, found that by putting two pendulums on the same structure they began to beat together in resonance. This force enveloped the pendulums, protecting them from outside vibrations and enhancing the movement's precision. Two centuries after A.L. Breguet succeeded in building a regulator with two pendulums, Francois-Paul Journe, another gifted watchmaker, was the first to find the way to put this phenomenon into a wristwatch: the remarkable Chronomètre à Résonance.
DIAL: in good condition with no signs of ageing.
CASE: scuffs and scratches throughout, consistent with age and wear of the timepiece, thin scratches on the 4 o'clock crown, small dent on top left crown, slight scratches on the exterior part of the clasp
