601.CI.0173.RX

The Hublot Spirit of Big Bang was originally introduced in 2014. As an alternative to the original Big Bang, it brings many of the features found on its source of inspiration to a barrel-shaped case. The version shown here has a case with a diameter of 45mm, which houses the self-winding caliber HUB4700. Reference 601.CI.0173.RX is done in Hublot's signature 'Black Magic' style.
