The Cerachrom bezel insert is manufactured in a single piece by Rolex from extremely hard ceramic.
This high-tech material is virtually scratchproof and keeps its vibrant colours over time.
Rolex broke new ground in 2013 when it introduced its first two-colour, single-piece ceramic bezel insert – blue on one half and black on the other.
One year later, the brand released the two-colour Cerachrom insert in red and blue – the GMT-Master’s original colours.
It carried out pioneering research to develop a red ceramic corresponding to its aesthetic and quality criteria.
