Unworn, Hublot Big Bang Original Unico King Gold Ceramic, Ref# 431.OM.1380.RX, box and papers.

Hublot Big Bang Original Unico King Gold Ceramic, ref. 431.OM.1380.RX, combines the bold Big Bang architecture with Hublot’s proprietary 18K King Gold and high-tech black ceramic. The polished and satin-finished 43 mm case frames a stamped satin-finished “Carbon Effect” dial, revealing the technical character of the in-house UNICO chronograph. King Gold is Hublot’s exclusive alloy, developed with platinum and high-tech additives for enhanced hardness and a warmer, more intense tone than traditional 18K gold. Powered by the HUB1280 automatic flyback chronograph with column wheel, the watch delivers approximately 72 hours of power reserve. Its open-heart architecture exposes the dial-side column wheel and double-clutch system, uniting contemporary design with Manufacture engineering. Condition: unworn in like-new condition, comes with original box and papers, including dated warranty documents.
