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.

Vacheron Constantin and the Hallmark of Geneva

The Hallmark of Geneva is a standard of excellence stemming from the tradition of Haute Horlogerie. It addresses the high-end Geneva watch brands.

It is the guarantee of origin (mechanical movement, assembly and regulation in the Canton of Geneva), quality of workmanship, durability and exceptional savoir-faire.

For over a century, the Hallmark of Geneva has been a reference for quality that is synonymous with the excellence of a traditional savoir-faire.
