Richard Mille RM 74-01 In-House Automatic Tourbillon

The RM 74-01 features grey Cermet, whose remarkable resistance to corrosion and scratches is particularly well-suited for a case application. Combining the lightness of titanium with the hardness of ceramic, grey Cermet consists of a metallic zirconium matrix associated with high-performance ceramic inserts. The hardness of the material, which is comparable to that of a diamond, was particularly appropriate for the case of this model. Many years of development on the part of Richard Mille and the IMI Group (a microtechnology specialist), went into designing this material and its singular grey colour. Meanwhile, the grade 5 titanium caseband, bridges and baseplate smoothly and harmoniously complement the case construction.
