Why Collectors Love This
This Hublot Big Bang Unico 42 reference 451.EX.5120.EX is a limited run of 250 pieces that brings the line's more compact case format to its in-house chronograph platform. Its automatic HUB1280 movement is a flyback chronograph caliber with a column wheel architecture, giving this watch the mechanical substance that matters most in the Unico line. The date is present but secondary to the openworked layout, where the skeleton dial keeps the movement's structure in constant view. In ceramic, the case measures 42mm across and 14mm thick, a size that keeps the Big Bang's assertive profile without pushing it into the largest end of the range. For a collector drawn to Hublot at its most architectural, that smaller format is much of the appeal. This reference shows the Big Bang after the Unico had become the collection's defining engine, with the material and dial treatment pushing the model's industrial language to the front.
