TECHNICAL SPECIFICATIONS OF THE RICHARD MILLE CALIBER EXTRA FLAT AUTOMATIC RM 033
Round case - available in titanium, 18k white gold or red gold. CALIBER RMXP1: skeletonized automatic winding movement with hours, minutes and off-center monoblock platinum rotor. Diameter: 45.70 mm x 6.30 mm.
MAIN FEATURES (MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)
POWER RESERVE Circa 42 hours. MONOBLOCK MICRO ROTOR Following on from the rotor with variable geometry that contributed to the success of Richard Mille’s automatic calibers, a new winding device is introduced in the RM 033. By using a platinum, decentrally positioned micro rotor, the barrel can be efficiently wound and an extra flat skeletonized movement can be achieved. FREE SPRUNG BALANCE WITH VARIABLE INERTIA This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shock and also during movement assembly and disassembly. Hence better chronometric results over time. The regulator index is eliminated and a more accurate and repeatable adjustment is possible thanks to 4 adjustable small weights located directly on the balance. CROWN In ceramic, with double seal O-ring and detailing in titanium, 18k red or white gold. BOTTOM PLATE, BRIDGES AND BALANCE COCK MADE OF TITANIUM The manufacturing of these components in grade 5 titanium - bottom plate with Titalyt® coating and bridges with PVD coating, allows the whole assembly to be given great rigidity, as well as precise surface flatness that is essential for the perfect functioning of the gear train. The skeletonized baseplate and the bridges were subjected to separate and extensive validation tests to insure optimal strength requirements. SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

OTHER FEATURES - Diameter of the movement: 33.00 mm - Thickness: 2.60 mm - Number of jewels: 29 - Barrel arbor – in 20AP steel - Balance: Glucydur, 4 arms, inertia moment 5.75 mg.cm2, angle of lift 53º - Frequency: 21,600 vph (3Hz) - Balance spring: Nivaflex - Shock protection: Incabloc 908.22.211.100 (transparent) CASE It retains the same characteristics and attention to detail in case design with a vast number of stamping and machining operations required for this round case with a total height just a mere 6.30 mm. The design and execution of this watchcase typifies the complete conceptual approach to all parts of the movement, case and dial. As a result, everything has been constructed according to an extremely rigorous specification. For example, a casing ring is no longer used and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by 4 titanium screws. The tripartite case is assembled with 16 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel and complemented by the additional integration of the lugs into the case’s torque screw system. The tripartite case is water resistant to 30 meters, ensured by two Nitril O-ring seals. SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE CASE This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well. INTERIOR FLANGES In carbon fiber, with hour index points filled with approved luminous material. Minute flange in black carbon fiber. DIAL In sapphire (thickness: 0.30 mm) with anti-glare treatment (2 sides). CRYSTAL - Bezel side: in sapphire (1800 Vickers) with anti-glare treatment (2 sides). - Thickness: 1.00 mm - Case back: in sapphire with anti-glare treatment (2 sides) - Thickness: at the center 1.00 mm and at outer edges 1.53 mm
