After months of research, Richard Mille unveils the first RM 011 case in NTPT® carbon, a brand new watchmaking material.
Originally developed for the sails of racing yachts, NTPT® carbon has quickly become a reference in composite materials. NTPT® carbon has been used for Formula 1 car chassis in the last two seasons, and in aeronautics for the fuselage of the future Solar Impulse 2 aircraft.
The NTPT® carbon's appearance is unique. 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, creating this distinctive visual effect that is reminiscent of precious wood. 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.
NTPT® carbon improves the rate of occurrence of breaking stresses by 25% and of micro-cracks by 200%.
The RMAC1 automatic caliber, which is recognizable by its large date at 12 o’clock, its month display at 4 o’clock and its flyback chronograph, is fully protected by the NTPT® carbon. The movement, made entirely of titanium, has a 55-hour power reserve provided by its double-barrel system wound by a variable geometry rotor.
