Description
Hublot Big Bang 451.CZ.4620.CZ 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.
