It is no. 54 of the limited edition of the Chronomètre à Résonance “Ruthenium” model, produced between 2001 and 2003, numbered 1 to 99. The Chronomètre à Résonance is one of the exceedingly rare and fascinating timepieces based on resonance, a natural physical phenomenon. The two closely positioned balance wheels synchronize each other by means of the resonance effect and naturally beat alternately. The negative effects of wrist and body movements are hence considerably reduced. The effects of resonance upon a timekeeper was first noticed by Antide Janvier around 1780 who made clocks with two pendulums beating in resonance. The idea was taken further by Abraham Louis Breguet who successfully completed pocket watches with twin resonant balances. Ruthenium is the sovereign among precious metals. Derived from platinum, its sheer rarity means it can only be used for certain limited series and exceptional creations, such as the Chronomètre à Résonance.
