About the Hublot Spirit of Big Bang

The Spirit of Big Bang, introduced in 2014, puts the Big Bang's layered construction, with its six H-shaped screws on the bezel, into a barrel-shaped (tonneau) case. Most models are skeleton chronographs with the movement visible through the dial.

Cases come in 32, 39, 42 and 45 mm and in titanium, ceramic, King Gold and colored sapphire: size and material decide the price. Check which strap is fitted; the quick-change system makes it easy to swap.

We stock 109 Hublot Spirit of Big Bang watches, from $11,350 to $95,920.
