The method
Four movements, one proof.
I
The workshop certifies
A verified maison examines the watch (movement, case, provenance) and draws up the deed of authenticity. Custoce verifies only professionals whose name stakes their expertise.
II
The passport is issued
The deed receives a dated, signed passport. From that instant its content can no longer be altered by anyone, not even by us. This is what we call permanence.
III
The owner space keeps
The owner gathers passport, photographs and service logbook. A discreet code lets a buyer, an insurer or an heir verify the watch in seconds, without an account.
IV
Custody is handed on
Sale, gift, inheritance: custody passes from owner space to owner space at the owner's invitation, and nothing is recorded until the next owner has confirmed. They receive the deed itself, and its whole lineage.
Permanence
And if Custoce disappeared?
Custoce is centralised for the service: a responsible third party, a recourse, an interlocutor. But the imprint of every deed is anchored in a public, unalterable register, independent of us, and no secret is left in your charge.
The suppleness of a trusted third party, the permanence of a public register.
