Calibre 1142 - Vacheron Constantin

Beating at a frequency of 3 Hz, the hand-winding Caliber 1142, powers one of the most coveted Haute Horlogerie complications: the chronograph. Caliber 1142 is an enhanced version of an existing caliber now meeting the demands of the Hallmark of Geneva and endowed with a higher frequency (3 Hz rather than 2.5 Hz) in order to improve the shock-resistance of the balance-wheel. Endowed with a 48-hour power reserve, this exceptional movement composed of 164 entirely hand-decorated parts displays the hours, minutes, small seconds and chronograph functions. In tribute to the 260 years of excellence perpetuated by the Manufacture, its balance-cock is embellished with an original scrolling pattern.
