Gold NTPT Carbon®

This new interpretation of NTPT technology is still based on the principle of inserting layers of quartz-TPT® or NTPT carbon at a 45° angle, in this case alternating with dozens of gold leaf layers, none of which are more than 10 microns thick.

Gold Quartz-TPT®

As gold is a noble material in chemical terms, it was very difficult for the NTPT and Richard Mille engineers to ensure it “fused” correctly with carbon and quartz.

NTPT®

NTPT® carbon is an exclusive material with a unique appearance. Its remarkable surface displays extremely regular undulations, as NTPT® carbon is composed of multiple layers of parallel filaments obtained by dividing carbon fibers. These layers, with a maximum thickness of 30 microns, are impregnated with resin then woven on a special machine that modifies the direction of the weft by 45° between layers. Heated to 120°C at a pressure of 6 bars, the NTPT® is then ready to be processed on a CNC machine in Richard Mille’s ProArt case factory. When compared to composite materials, whose exceptional physical properties are already well known, NTPT® carbon improves the rate of occurrence of breaking stresses by 25% and of micro-cracks by 200%.

TITANIUM

Because titanium is as strong as steel but much less dense, it is generally used in aeronautics and medical fields for its lightness and biocompatible properties. Grade 5 titanium has excellent properties that combine strength with resistance to extreme temperatures and corrosion.

CARBON NANOTUBES

An extremely robust composite based on injected carbon nanotubes, a material that perfectly protects the movement and the tourbillon at its center from shocks. Carbon nanotubes are extremely durable (two hundred times stronger than steel) and very light. They are capable of absorbing far stronger impacts than traditional carbon fiber due to their structure with its excellent surface-volume ratio. The case is created by injection molding carbon nanotubes under high pressure into a black polymer.

Translucent composite, injected carbon nanotubes

The carbon nanotubes are extremely resistant (200 times more resistant than steel) and very light.
They are more resistant to impacts than carbon fibre thanks to their structure, which features an exceptional surface/volume ratio. The nanotubes are injected into a mould containing a green-yellow polymer.
This gives the case its final shape and translucency.

CERAMIC TZP-N

This ultra-tough black ceramic material has a low density (6g per cm3) combining extreme resistance to scratches with a very low coefficient of thermal conductivity. Composed of 95% Zirconium compound stabilized with Yttrium, TZP-N allows for a perfect finish with brushing or microblasting and hand polished anglage.

GOLD

Gold is a very rare substance which has held a fascination for humankind over the course of many centuries. On a mythological level It was also used as a symbol of the sun's warmth and importance for life. 18K red gold is specifically used at Richard Mille as it is the 'warmest' expression of this metal. The magnificent color of red gold also provides a beautiful contrast when combined with Richard Mille's movement design or case parts in ceramics or titanium.
