The extra thin Hublot Classic Fusion replica watch is avialable in two size, 44mm and 42mm. It is comfortable and easy to adjust. Gold hour markers and lugs, a tiny date window at 3 o'clock position. Brushed ceramic bezel, black dial with unique pattern. If you are wondering about the "Fusion" part of the name, well, Mr. Biver considers the original Big Bang watches to be a "fusion" of materials.
