The manufacturing of the GMT-Master II’s red and blue Cerachrom bezel insert involved years of research and development. Its composition integrates rare earth material to obtain the red colour and a complex chemical compound to turn its other half into blue. The final result comes after the component is heat-treated for many days at temperatures as high as 1,600 C°.
