Swiss luxury watchmaker Franck Muller has launched limited-edition timepiece dubbed “Encrypto” that it’s calling “the world’s first functional bitcoin watch.”

Aesthetically, the dial of the watch – launched in partnership with cryptocurrency trading platform Regal Assets – sports bitcoin’s logo and a QR code of bitcoin’s genesis block address.

The face also includes a laser-etched QR code for a public wallet address that can be used to deposit bitcoin and check its balance. An included sealed USB stick stores the private key, Regal Assets announced Wednesday.

The “deep cold storage” wallet uses “offline generated, non-deterministic TRNGs (True Random Numbers Generated) that cannot be hacked,” according to the announcement.
