New Chronomètre à Résonance

New Chronomètre à Résonance from the F.P Journe Souveraine collection

10 YEARS FOR THE CHRONOMETRE A RESONANCE

Celebration of the emblematic F.P.Journe Timekeeper 2010 commemorates the 10 year Anniversary of the renowned Chronomètre à Resonance with a new edition now featuring a 24 hour indicator.

An emblematic timepiece that will significantly mark the research on precision made by master watchmaker François-Paul Journe. This unique watch represents one of the wildest challenges ever in the field of the mechanical watch! Utilising the natural resonance phenomenon, this exceptional mechanism revolutionized the classic standards of watch-making by offering an unequalled precision for a wristwatch. The first applications of the resonance phenomenon in horological science date back to the 18th century, by French master watchmaker Antide Janvier (†1840).

He observed the negative effects of these waves on clocks and then conducted his own research on ways of using this phenomenon in the operating of regulators.
