Watch Certificate™ is a French technology platform developed by Tradee SAS in Paris, dedicated exclusively to the watch industry as the most comprehensive digital passport solution on the market. The platform serves manufacturers, retailers, authorized workshops, auction houses, second-hand dealers, and marketplaces with a turnkey white-label system that unifies warranty management, ownership transfer, service history, and customer data into a single blockchain-secured digital certificate — deployable in days without modifying existing internal tools or infrastructure. Accessible in over 150 countries, it enables automatic sell-out detection and delivers customer insights that drive loyalty and post-purchase value across the entire watch ecosystem.

Each Watch Certificate™ is generated through a rigorous 53-checkpoint inspection carried out by a certified watchmaker, accompanied by a minimum of eight high-definition photographs, and validated by an independent expert to produce an unfalsifiable, dynamic record of a watch's authenticity, condition, and market value. The certificate acts as a living passport throughout a watch's entire lifecycle: it proves provenance to insurers, facilitates transparent transactions in the pre-owned market, enables secure ownership transfer, blacklists stolen timepieces across a global network, and activates automated maintenance reminders and personalized brand campaigns. Data is secured with institutional-level protection fully compliant with GDPR and international data privacy standards, with the entire record anchored immutably on the public blockchain — ensuring continuity and authenticity regardless of any future change in platform ownership.
