Anchored by Hublot's Calibre HUB1280 automatic movement, this Big Bang Unico beats at 28,800 vph, houses 43 jewels across 354 components, and delivers a power reserve of approximately 72 hours. A column-wheel chronograph mechanism drives two sub-dials tracking 60-minute and 60-second elapsed time, while a date window sits at the 3 o'clock position.
The open-worked skeleton dial features Arabic numeral and index hour markers alongside luminescent silver-tone hands, all protected by scratch-resistant sapphire crystal. A screw-down crown and transparent case back complete the 42mm round case, which carries a water resistance rating of 100 meters / 330 feet.
Offered in Swiss Made designation with both the original box and original papers included, this men's luxury chronograph represents the Big Bang series in a bold blue-and-titanium configuration suited for the collector seeking an avant-garde mechanical timepiece.
