The Big Bang watch marked Hublot's revival under Jean-Claude Biver's leadership, who introduced the 'Art of Fusion' concept. Launched in 2005, just a year after Biver took the reins, it pays homage to the brand's past while incorporating modern elements. This particular model, the reference 341.PX.7180.LR.1204, boasts a smaller 41mm case and is powered by the HUB4300 movement, a variation of the ETA 2894-2. The case is crafted from red gold and features a dazzling diamond-set bezel. A stunning addition to the Big Bang family.
