Cerachrom bezel insert
A concentration of high technology
The Yacht-Master II, available in Oystersteel or 18 kt yellow gold, features a bidirectional rotatable bezel fitted with a 60-minute graduated Cerachrom insert in blue ceramic. Extremely hard and virtually scratchproof, the high-technology ceramic used by Rolex requires special tools for its machining. Its stable color is unaffected by ultraviolet rays, and thanks to its chemical composition, this ceramic is inert and cannot corrode.
On this blue Cerachrom insert, the molded, recessed graduations and numerals are coated with platinum or yellow gold via PVD (Physical Vapor Deposition). The first half hour of the graduation is set out minute by minute. With the bezel in the neutral position, the final 30 seconds of the countdown can be read in more detail via the chronograph center seconds hand. The graduated bezel, whose knurled edge offers excellent grip, also allows the wearer to easily measure time intervals – for example, the sailing time between two buoys.
