In 2019, Vacheron Constantin introduced digital certification of authenticity using Blockchain technology. Vacheron Constantin was among the first watchmakers to integrate Blockchain technology as part of an innovative service to clients and an increasingly environmentally friendly approach to certification involving less paper. The watches in Les Collectionneurs collection are thus accompanied by a digital certificate of authenticity that is perfectly forgery-proof. Initially reserved for that collection, now all Vacheron Constantin timepieces will be delivered by the end of 2021 with a blockchain-based digital passport, secured by the Arianee technology.
