The register of ownership
The papers prove the watch. Custoce proves it is yours.
An exceptional piece changes hands four or five times in a century. Its papers, never. Custoce keeps the register the market lacks: established by the certifying maison, kept for the duration, handed on with the watch.
What you receive

The vault
Your pieces, their seals and their service logbook gathered in a place of custody that you alone command, open to a buyer, an insurer or an heir, without an account.
Enter the vault
The logbook
Services, interventions, strap changes: every gesture recorded by a workshop joins the memory of the piece and follows it when it changes hands.

The method
An accredited maison examines the piece and draws up the deed. The seal is affixed, dated, signed, and its content can no longer be altered, by anyone. The vault keeps, then custody is handed on, from owner to owner.

PermanenceDiscretion
No owner's identity is visible: neither to the public, nor to the maison that certified the piece. It is a property of the service.
Our commitmentsRecourse
A responsible interlocutor in case of lost access, theft, succession or dispute. Nothing to remember, nothing to keep safe.
