====== Cerachrom ====== **Cerachrom** is a special type of [[ceramic]] used by [[Rolex]]. Rolex was among the pioneers of ceramic watch cases and components. Their proprietary Cerachrom ceramic is designed to be highly resistant to fading in sunlight and corrosion by water. Most Cerachrom bezels include numerals and marks that are coated in gold or platinum through [[PVD]]. Cerachrom is used in the modern [[Rolex GMT-Master II]], [[Rolex Submariner]], and [[Rolex Sea-Dweller]] watch [[bezel]]s. {{tag>Rolex Terms}}
