The name “Cerachrom” comes from the abbreviation “ceramic” and the ancient Greek suffix “chrom,” which means color. The shades available in ceramics are limited by how they are made. Generally, color comes from mineral pigments that are heated to high temperatures, making the ceramic dense and giving it its unique hardness.

However, the color red itself lacks a stable mineral pigment, making it hard to create a Cerachrom component in red. Despite this, Rolex started making red ceramics using a secret process. But this innovation is only part of the story for the brand; it’s more accurate to say that it’s still being completed with the distinctive red and blue Cerachrom bezel.

In this way, half of the red ceramic bezel can be changed to blue. To achieve this, the part of the bezel representing the night (6 p.m. to 6 a.m.) needs to be soaked in a specific solution.
