HUB1770 Featuring a “barrel” shape in close fusion with the Spirit of Big Bang collection’s case, this entirely skeletonized automatic winding caliber displays two very popular functions: a large off-center date at 2 o'clock indicated by two discs and moon phases in a window at 6 o'clock. The small second hand displayed at 9 o’clock. Despite the presence of two complications, the movement retains a reasonable thickness. Ceramic For Hublot, materials are an integral part of their watches’ design. They must complement their design, while protecting their mechanism and withstand the test of time. As such, the Manufacture has chosen to use high-tech ceramic for certain bezels and cases; it is an ultra-tough and almost entirely scratch-proof material (apart from the diamond) with a base of zirconium sintered at very high temperatures.
