F.P. Journe Chronomètre À Résonance Réf. RN

The F.P. Journe Chronomètre à Résonance is one of the most technically significant watches in modern independent watchmaking, showcasing François Paul Journe's pioneering interpretation of the natural phenomenon of resonance. This example is presented in a 40 mm platinum case measuring 9.1 mm thick and features the highly sought after grey dial with twin independent time displays, dual subsidiary seconds, and a power reserve indicator. Fitted to a premium leather strap with a matching platinum pin buckle, the Chronomètre à Résonance combines timeless design with exceptional functionality, allowing two independent time zones to be displayed while maintaining the elegant proportions that have made this reference a favourite among collectors.

Powering the watch is the manually wound Calibre 1499.3, manufactured entirely from 18 karat rose gold and visible through the sapphire crystal case back. The movement features twin gear trains, twin balances, and F.P. Journe's celebrated resonance system, enabling both regulating organs to synchronise naturally for outstanding chronometric stability. Operating at 21,600 vibrations per hour with a power reserve of approximately 40 hours, the movement is finished to the highest standards with polished screw heads, chamfered bridges, circular graining, and beautifully hand finished steel components. Combining groundbreaking mechanical innovation, exceptional craftsmanship, and enduring collectability, the 40 mm platinum Chronomètre à Résonance remains one of the most desirable independent timepieces ever created.
