The Hublot Big Bang Integral Time Only King Gold 457.OX.1280.OX is the compact 38mm execution of Hublot’s integrated-bracelet Big Bang, crafted in satin-finished and polished 18K King Gold with a fully integrated King Gold bracelet for a seamless, modern profile. This reference is not a chronograph; it is a time-and-date automatic watch designed around a clean, legible dial. Verified specifications describe a polished black dial with a mixed marker layout (Arabic numerals and index hour markers), paired with a sapphire crystal and a sapphire display back, and engineered to 100 meters (10 ATM) of water resistance for practical everyday wear.
Power comes from the Hublot Caliber HUB1115 self-winding movement, delivering approximately 48 hours of power reserve and supporting the core functions of hours, minutes, central seconds, and date. The integrated King Gold bracelet is secured by an 18K King Gold deployant clasp, maintaining the watch’s continuous case-to-bracelet silhouette and premium sport-luxury execution.
