About the Big Bang family
The Big Bang was introduced in 2005 as a 44 mm chronograph built from layers of different materials, with the six H-shaped screws on the bezel inherited from the original Hublot. It launched the brand's Art of Fusion idea and quickly became its main line.
The catalog lists more than a hundred references, including chronographs with the in-house Unico movements such as the HUB1242 and HUB1280, in King Gold, ceramic, titanium, carbon and sapphire. Dealers identify the generation, size and material from the reference and check the strap system and papers.
