CASE IN CARBON TPT
Carbon TPT
is an exclusive material with a unique appearance. Its remarkable surface displays extremely regular striations, as Carbon TPT
is composed of multiple layers of parallel filaments obtained by separating carbon threads. With a maximum thickness of 30 microns, the Carbon TPT
layers are saturated with resin then piled onto a special machine that modifies the orientation of the fibres by 45° between layers. Once it has been heated to 120°C and subjected to a pressure of 6 bars, the Carbon TPT
is machined at Richard Mille's case factory.
The case of the RM 25-01 is water resistant to 100 metres, ensured by two Nitrile O-ring seals. The case is assembled with spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.
