Hublot Square Bang Unico King Gold Pavé 42 mm Transparent Dial with Diamonds Polished 18K King Gold Rubber Strap 821.OX.0180.RX.1604

By developing its own automatic chronograph movement, Hublot wanted it to be – like all of its creations – the first, different and unique. As the soul of the watch, this movement with an “open heart” reveals its completely re-imagined design, with double coupling system and column-wheel from the dial side as well as a 72-hour power reserve. Its construction of 354 components has been simplified as much as possible to improve reliability and robustness.
