UNPARALLELED PERFORMANCE
Hublot’s flagship model, the Big Bang collection has undoubtably revolutionised the watchmaking universe – bringing together extraordinary design elements that never fail to make an impact.

Thanks to technical optimisations, the movement has been reduced by 1.3mm in thickness, while still retaining key features such as a double coupling system, which can be viewed from the side of the dial, as well as a 72-hour power reserve.
DESIGNED TO STAND THE TEST OF TIME
Ultra tough, this distinctive model presents a matte black skeleton dial with Arabic numerals and baton hour markers.
The 44mm satin-finished and polished titanium case is paired with a black ceramic bezel with 6 H-shaped titanium screws, and a robust black rubber strap with a titanium deployant buckle clasp.
Powered by the performance-driven HUB1280 UNICO manufacture self-winding chronograph flyback movement, this incredible model is equipped with a 72-hour power reserve and water resistance to 10 bar (100 metres).
