Blockchain Authenticity
Blockchain Provenance
We're building a blockchain-anchored Certificate of Authenticity for every watch we sell — an on-chain record that ties a specific reference and serial to its inspection history, photos, and ownership transfer. The system is in development; this page describes the model so you know what's coming.
What it will do
- Each watch gets a unique on-chain record at the moment of authentication, before listing.
- The record stores the reference, serial, inspection date, condition notes, and a hash of the inspection photos. The full photo set lives off-chain at a stable URL anchored by that hash.
- Ownership transfers are signed by the buyer's wallet at delivery. The chain of custody is public and verifiable.
- You can verify any Open Wrist watch by entering its serial here, with no account required.
Status
Smart contract is in private testing on Polygon Amoy. Mainnet deployment is targeted for later this year. Watches sold before launch will be back-issued an on-chain record once the system goes live, at no cost to the buyer.
Until then
Every order ships with a written, signed Certificate of Authenticity that lists the reference, serial, inspection date, and condition. Keep it with your papers — it's the receipt the on-chain record will reference when issued.
