About the Spirit of Big Bang family
The Spirit of Big Bang was introduced in 2014 with a tonneau-shaped case, a departure from Hublot's round watches, while keeping the layered construction and visible screws of the Big Bang.
The catalog includes chronographs with the HUB4700 caliber, based on the high-frequency El Primero, in titanium, King Gold, ceramic and sapphire. Dealers identify the material and dial from the reference and check the strap and papers.
