Swiss luxury watchmaker Hublot is making 210 of the watches as a reference to 21 million, the fixed global limit for bitcoins.

Each watch will bear the identification number of the bitcoin transaction engraved on its bezel. And the blue leather watch strap sports a futuristic design that Hublot says is inspired by blockchain, the technology underlying bitcoin and other cryptocurrencies.
