A watch from an accredited maison on a wooden counter

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

Steel vault door

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.

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.

Our commitments

Permanence

The imprint of every deed is placed in an unalterable public register, independent of us. The proof would outlive us.

Permanence

Discretion

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 commitments

Recourse

A responsible interlocutor in case of lost access, theft, succession or dispute. Nothing to remember, nothing to keep safe.
