In a patent released last month by Rolex, the brand said it wants to improve on how Omega and other watch brands use NFC chips in warranty cards to access information about the watch.
Rolex said it doesn't want owners to download third party apps or create user accounts which could be susceptible to security breaches.
Rolex wants to use blockchain technology to store information that can be displayed on a website once a watch certificate card is scanned. It’s unclear if the final product will reveal personal information about ownership. But it could be a way for current owners to communicate with Rolex Service Center for warranty work, according to the patent.
More importantly, future Rolex watches could have unique identifiers for the case, movement and bracelet each. The “string of alphanumeric characters comprising of eight random digits” for each part of the watch could be stored via blockchain technology and engraved in a way that can be scanned, the patent said.
