Richard Mille Automatic Winding – RM 023 INTRODUCTION Automatic winding movement with hours, minutes, seconds, date and variable-geometry rotor. POWER RESERVE Around 55 hours ( ±  10%). Baseplate And Bridges Made Of Grade 5 Titanium Production of these components in grade 5 titanium with black PVD or Titalyt® coating confers great rigidity on the entire assembly, as well as the precise surface flatness essential for perfect functioning of the gear train. The skeletonised baseplate and bridges were subjected to separate and extensive validation tests to optimise its resistance capacities. DATE DISPLAY Semi-instantaneous, the calendar disc of sapphire crystal is treated with nonreflective coating on both sides. Variable-geometry Rotor The RM 023 uses variable geometry to optimise the rotor’s winding motion. Rotor specifications: • Arm in grade 5 titanium • High palladium content 18K white gold weight segments • Weight segment with 6 possible positions adjusted by screws in grade 5 titanium • Ceramic ball bearings • Unidirectional; anti-clockwise winding direction This exclusive Richard Mille design makes it possible to effectively adapt rewinding of the mainspring to the user’s activity level, in sporting or non-sporting environments. By adjusting the six-position rib, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or to slow it down during sporting activities.
