The BIG BANG Unico collection represents the perfect fusion of Hublot's award-winning iconic design and its Manufacture movement, the UNICO chrono !The Unico movement has been entirely designed, developed, machined and assembled by micro-mechanics, engineers and watchmakers at Hublot. The movement is a flyback chronograph which can be reset atany time, and which is unique in the watchmaking industry, two push-buttons, with date indicator, and featuring a uniquely positioned mechanism with dual coupling and the famous "column wheel" visible on the dial side.
