Caliber 1731

A tribute to Jean-Marc Vacheron, founder of the Manufacture in 1731, minute repeater Calibre 1731 with its impressive 65-hour power reserve is a record 3.90 mm thin. The challenges involved in such extreme slenderness are compounded by the ingenuity of a silent flying strike governor that ensures the regular rhythm of the hammers in striking the gongs. It combines purity, regularity of sound with the excellence of hand-crafted decoration and finishing right the way through to hidden elements.
