Quartz TPT® was chosen for the RM 67-02 bezel and caseback. Its remarkable surface displays extremely regular striations, as they are composed of many layers of parallel filaments obtained by dividing silica threads.
Quartz fibres are generally used for very high-performance applications due to their resistance to high temperatures, their strength, and their transparency to electromagnetic waves.

These layers, with a maximum thickness of 45 microns, are impregnated with two new resins developed specially for Richard Mille, yellow and green for Wayde's native South Africa.

They are then compiled on a special machine that modifies the orientation of the fibres between each layer by 45°. Once it has been heated to 120°C and subjected to a pressure of 6 bars, the material is then ready to be processed on a CNC machine in Richard Mille's ProArt case factory.

Spline screws in grade 5 titanium for bridges and the case

This permits better control of the torque applied to the screws during assembly. 
These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

The brand developed this new elastic strap, known as a ‘comfort' band, especially for watches worn by the athletes of the Richard Mille family.

"It offers an alternative to Velcro® for even more

lightness. 

The reinforced elasticity of this entirely seamless and

non-slip strap allows it to perfectly fit the contours of

each wrist, adapting to individual morphology,

improving comfort even further."
