This is a new and unworn watch Hublots flagship model, the Big Bang collection has undoubtably revolutionised the watchmaking universe bringing together extraordinary design elements that never fail to make an impact. The Big Bang Unico model features the Unico 2 calibre, designed to equip smaller chronographs with the power of the original movement. 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. Ultra-tough, this model boasts a striking matte black skeleton dial, presented in an ultra-lightweight, 42mm titanium case. The integrated satin-finished and polished titanium bracelet provides flawless strength and mirrors the sharp edges of the case. Powered by the reliable in HUB1280 UNICO manufacture self-winding chronograph flyback movement, this timepiece offers a 72-hour power reserve and is water resistant to 10 bar (100 metres).
