The technical-aesthetic credo of Richard Mille is to open up fine watchmaking to the worlds of art, sport and lifestyle, the purpose here was to tackle the archetype of very high watchmaking art, with performance as an added bonus. This model guarantees extreme performance over the long term : while current standards allow a variation in accuracy of 5 to 8 seconds per day, our specifications for this model demanded 20 to 30 seconds per month. These figures are quite simply exceptional, and indicate a truly extraordinary timepiece.

FUNCTION INDICATOR In a manner similar to a car’s gearbox, the function indicator allows one to see the winding, neutral and hand setting positions as the crown is pulled out. Each position is indicated via a hand at 5 o’clock displaying the following functions: W (Winding) – N (Neutral) – H (Hands).
CASE The design and manufacture of the watch embody a complete conceptual approach to the case, dial and every part of the movement. The timepiece is created as a harmonious whole according to extremely rigorous specifications. The casing ring is eliminated, and the movement is fixed to the chassis with three titanium screws and silent blocks (ISO SW). A first at Richard Mille, the case is composed of four parts, and is assembled using 12 Spline screws in grade 5 titanium and wear-resistant washers in 316L stainless steel. The system is completed by the incorporation of the lugs as separate elements of the case design. The case is water-resistant to 50 meters.
BARREL AND BALANCE BRIDGE IN GRADE 5 TITANIUM These components are made from grade 5 titanium treated with a black PVD coating, which gives the whole structure great rigidity and excellent surface flatness, both essential to the perfect functioning of the gear train.
