‘it was unimaginable for us to create such a beautiful and high-performance movement only to cover it up.
We owed it to ourselves to set it off while protecting it from externalities in a suitable housing, with “indestructible” our watchword.’

Carbon TPT® consists of over 600 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 compiled on a special machine that modifies the orientation of the bres between each layer by 45°.
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 factory.
Carbon TPT® is renowned for its excellent resistance to microcracks and splits.
The complete case construction is water resistant to 50 metres thanks to two Nitrile O rings, and is assembled using 20 spline screws in grade 5 titanium and 316L stainless steel washers.

This added security system prevents accidental overwinding of the watch, which could result in damage such as snapping the winding stem or putting too much pressure on the barrel spring.
