F.P. Journe 1499.3

The F.P. Journe Caliber 1499.3 powers the Chronomètre à Résonance, the only wristwatch in the world featuring acoustic resonance between two balances. This emblematic timepiece represents François-Paul Journe's groundbreaking chronometric research, adapting a principle explored by Antide Janvier and Abraham-Louis Breguet in the 18th century to a wristwatch for the first time. The twin balances beat in perfect synchronization through the natural phenomenon of resonance, recovering energy dissipated by each other and achieving unparalleled precision. The resonance system is particularly suited to wrist movements that would normally disturb watch mechanisms. The dial features dual displays: a 24-hour digital indicator at 9 o'clock defining day and night hours, and a 12-hour analog display at 3 o'clock for local time. Movement manufactured in 18K rose gold. This version was produced between 2010 and 2019, representing the second generation with improved resonance coupling.
