The Hublot Big Bang Unico Sapphire automatic flyback chronograph is the first new release in anticipation of Baselworld 2016. The case middle, bezel, and case back were all cut out of blocks of sapphire crystal, which is scratch resistant and is almost as hard as diamonds. Titanium was used for smaller elements, including the screws, crown (additionally molded with silicon), and the deployant buckle. Overall the watch measures 45 mm in diameter. The skeletonized dial is made of transparent resin and features the automatic Unico HUB1242 flyback chronograph movement.
