The Unico 2 caliber was designed to equip smaller chronographs and also open the world of Hublot to new enthusiasts. It retains the unique design of its former version with a double coupling system visible from the dial side as well as a 72-hour power reserve. But thanks to various technical optimizations, including the introduction of a new, flatter automatic winding system, it has been reduced by 1.3 mm in thickness.
Popular in motor racing, carbon possess unrivalled mechanical qualities. It is ultra-lightweight, resists torsion and stands out with its optimal relationship between weight and resistance. This high-tech material is in the form of a fiber mesh embedded in an epoxy resin. Hublot also uses a 3D carbon where the fibers are woven on three planes. Other models use a “frosted” carbon with colored inclusions.
