Swiss luxury watchmaker Vacheron Constantin has announced the launch of its official Certified Pre-Owned watch program, in collaboration with leading second-hand watch retailer Watchfinder. The program allows any timepiece produced by the brand since 1755 to be sent back to the official brand service for restoration and maintenance. All certified pre-owned watches will come with a minimum two-year global warranty, a digital passport, and a CPO certificate, along with exclusive packaging and an official seal.
