The lexicon.

The words of the house. Custoce speaks the language of the register, not that of technology: here are its words, in the order a watch meets them, from recording to handing on.

Custoce\kys.tɔs\

MASCULINE NOUN

From the Latin custos, custodis: the guardian.

The register of reference where the ownership of fine timepieces is established, kept and handed on.

By extension: the house that keeps this register and watches over the owner spaces entrusted to it.

The register: The great book where every watch is recorded, with its history from hand to hand. A register of reference, in the spirit of a land registry: it states who owns what, and never speculates on value.
The watch: The watch as it is recorded at the register: its brand, its model, its serial number, its photographs. A watch exists only once, and its record follows it for life, whoever its successive owners may be.
The house: The watchmaker or the jeweller who records their watches at the register. Their name remains attached to the watch on the certificate, forever: certified at the origin by its house.
The boutique: The point of sale where the watch meets its owner. It is at the counter, at the moment of the sale, that the boutique hands over the owner space.
The digital passport: The document the house issues for a watch as it is recorded at the register. To issue a watch's passport is to attest that it exists, that it is the one described, and that a house answers for it. The passport outlives everything: it is never withdrawn.
Permanence: What is recorded at the register is never rewritten. The imprint of every event is placed in a public, lasting book, independent of Custoce: the service is rendered by a house, the proof is made to last longer than it.
The owner space: The owner's personal place. Their watches live there with their documents: certificates, attestations, service logbook. The owner space opens once, is kept for life, and is handed on.
The titleholder: The person in whose name a watch is recorded at the register. The current owner, the one the register recognises.
The certificate: The public page of a watch, which anyone can consult by scanning its code. It shows the passport, the house of origin, the status of the watch. It never reveals the titleholder's identity.
The attestation: The document the titleholder can produce to assert their ownership: to an insurer, a buyer, an expert. The certificate is consulted; the attestation is presented.
The claim: The gesture by which the owner brings their watch into their owner space, with the code handed over at the sale. The watch was waiting for its owner; it is claimed.
The transfer: The gesture by which a watch changes titleholder: a sale, a gift, a bequest. Ownership passes from one owner space to another, cleanly, and the register keeps the trace.
The recovery sleeve: The document the titleholder sets aside, the old way, on paper. The day access to the owner space is lost, or the day of a succession, the sleeve lets you recover what is yours.
Custody: The way Custoce watches over the passports on behalf of the titleholders. Nothing to install, nothing to keep yourself, nothing to lose. A house that answers for your possessions, not an algorithm.
