Hublot Big Bang Gold

The blueprint for Big Bang’s evolution lies in a chic and incisive style. Its case, featuring a vertical satin finish like the bezel, stands out elegantly around the highly sober matt black dial which has no numerals; instead it is graduated by uniform indexes the same colour as the case. Increasingly classic, the Big Bang is now asserting itself as an icon of 21st Century watchmaking.
