Cerachrom bezel
Rolex developed and patented the Cerachrom bezel for specific Professional models to ensure lasting beauty and functionality even after exposure to the most extreme conditions. Fashioned from extremely hard ceramic material, it is virtually impervious to scratches, and its colour is unaffected by ultraviolet rays. Its diamond polished surface presents an exceptional lustre. The engraved 24-hour graduations are coated with a thin layer of platinum.
