Big Bang 20th Anniversary All Black Ref. 431.CI.1340.RX

Developing his own automatic chronograph movement, Hublot wanted it to be – like all his creations – the first, different and unique. The heart of the watch, this "open-hearted" movement reveals its completely revised design, with a dual-clutch system and dial-side column wheel, as well as a 72-hour power reserve. Its construction of 354 components has been simplified as much as possible to improve its reliability and robustness.
