Hublot celebrated 15 years of its flagship Big Bang model with the introduction of the first-ever Big Bang with an integrated metal bracelet, the perfect replica Big Bang Unico Integral. The watch represents an extension to the existing Big Bang Unico 42 series, but also notably features an updated case design whose first link is fused with the new bracelet and whose chronograph pushers recall those of the very first Big Bang released in 2005.
Fully visible behind the sapphire dial is the in-house, skeletonized Unico HUB1280 caliber, equipped with a chronograph function driven by a column wheel and a horizontal double-clutch mechanism. The self-winding movement, which comprises 354 components, boasts a flat automatic winding system and stores a power reserve of 72 hours, or three days, in its mainspring barrel. Its column wheel is visible from the front, behind the applied indices and subdials at 3 o’clock for elapsed minutes and 9 o’clock for running seconds.
