The card standard
Every registered watch is issued with a physical certificate. The card opens the record and stays with the piece.
Each card carries an NFC inlay and a printed Certificate ID. Both open the same record.
The card is bound to the watch at sale, not in production. The number on the caseback is entered once, and the server records the date.
One card. One watch. One entry.

Reading the card
Hold a phone to the card. The record opens.
It shows the model, the number on the caseback, the registration date, the standing of the guarantee, and any service recorded since.
If the card cannot be read, the printed Certificate ID opens the same record through Verify.
Common questions
When is a card bound to a watch?
At sale. Before that it belongs to the maison and to no particular piece.
What is the number printed on the card?
The Certificate ID. It is not the watch's serial number.
Does this work for watches without individual serial numbers?
Yes. Each activation creates its own record, with its own Certificate ID, registration date and guarantee.
Can a card be copied?
A card can be copied. A registry entry cannot. Cryptographic card authentication is available where a maison requires it.
Does the card prove the watch?
The card proves the record. The maison binds the record to the watch at sale.
What if I lose the card?
The record remains. A replacement can be issued where the watch carries its own serial number; where identity rests on a shared model reference, the certificate is the credential and cannot be reissued.
Do I need an app?
No. The record opens in the phone's browser.
