In 2018, Hublot launched the Big Bang Unico 42 mm, a new diameter that opened up the world of unisex watches to the brand. This diameter was made possible thanks to the second version of the brand's UNICO proprietary manufacture movement, the calibre HUB1280, which is protected by four patents. The movement is just 6.75 mm thick, allowing for a thinner case measuring 14.5 mm.
Six versions of the Big Bang Unico 42mm are available, in polished/satin-finished King Gold or titanium, with a “naked” case, a bezel set with 126 diamonds (approx. 1.1 ct.), or fully paved with 296 diamonds (approx. 1.9 ct) on a white lined structured rubber strap. The skeleton dial is matt white and the inner bezel is made of white composite resin.
The self-winding Unico HUB1280 flyback chronograph movement with column wheel beats at a frequency of 4 Hz (28,800 vph) and has a power reserve of 72 hours.
