Ulysse Nardin’s every watch will have its own digital fingerprint as the brand deploys blockchain certification to all its collections.
Blockchain is a technology that can be used to store and transmit information or transactions. It is a global digital database shared among multiple users that can, at any time, using a cryptographic system, verify the validity of information, add data and record a transaction. Ulysse Nardin’s approach used here is to store the “digital signature” of all PDF warranty certificates in the form of a “hash” – i.e. an encrypted string of characters – on the Bitcoin blockchain.
Therefore, a digital document like a warranty certificate in this case, when protected on the blockchain, becomes tamper-proof. The registers of “hashes” are publicly accessible, anywhere in the world, at anytime, thereby removing the risk of losing, forgetting or falsification of physical warranty cards traditionally provided with the watch at the time of purchase. Another advantage is that this certificate becomes extremely useful for the after-sales service (a reliable transaction history) or when it is offered as a gift or resold (used market). The physical guarantee card will continue to exist, since thanks to its “bubble tag”, customers will be able to extend the watch warranty to 5 years and thus directly generate online blockchain warranty certificate.
So, essentially, when a customer buys a Ulysse Nardin watch, they must enter it on the Ulysse Nardin website using the physical “prooftag” warranty card. They will then receive a personalized digital certificate on their name in a PDF format containing all the data and information about the purchased product (model, watch serial number, warranty card number and warranty end date). The signature of this warranty document is anchored in the blockchain via its “hash”, i.e. the document’s digital fingerprint.
“We decided to use the most secure and most recognized solution. Also, according to a satisfaction survey that we send to our customers with the certificate, 90% see the value of using the blockchain to protect their certificate and 100% are satisfied with receiving a protected digital certificate,” stated Stéphane Carlier, Chief Digital Officer of Ulysse Nardin.
