Hublot Big Bang · Ref. 421.OX.1180.RX

About This Watch

The Hublot Big Bang Unico King Gold represents the pinnacle of the Big Bang line, combining the brand's proprietary King Gold alloy with the cutting-edge HUB1280 manufacture movement. King Gold is Hublot's exclusive 18-karat red gold alloy, enriched with platinum to resist oxidation and maintain its warm, rosy hue far longer than conventional rose gold. The 42mm case diameter — refined down from the original Big Bang's 44mm — offers a more contemporary and versatile wearing experience while retaining the model's bold visual DNA. The skeletonized dial provides a mesmerizing view of the HUB1280 caliber at work, with its flyback chronograph mechanism visible through the sapphire crystal. This movement represents a significant achievement for Hublot, delivering 72 hours of power reserve and a column-wheel flyback chronograph entirely designed and manufactured in-house. The flyback function allows instant chronograph reset and restart without the traditional stop-reset-start sequence — a complication prized by those who need rapid successive timing. The six H-shaped screws on the bezel, rendered here in matching King Gold, maintain the Big Bang's signature aesthetic. The rubber strap with deployant buckle keeps the watch comfortable despite its precious metal weight. This is a watch for collectors who want uncompromising manufacture watchmaking wrapped in a distinctly modern and luxurious package.
