CALIBRE RMAL1
Skeletonised automatic-winding movement with hours, minutes, seconds and variable-geometry rotor.
POWER RESERVE
BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM
The baseplate and bridges are in wet-sandblasted grade 5 titanium, which has been PVD/Titalyt® treated and stretched to ensure supreme rigidity and impeccably smooth surfaces.
The skeletonised baseplate and bridges were subjected to separate and extensive validation tests to ensure they met rigorous strength requirements. Consequently, the RM 35-02 can withstand accelerations of up to 5,000 g’s.
VARIABLE-GEOMETRY ROTOR
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.

RM 11-03 McLAREN, RICHARD MILLE'S TAKE ON THE GRAN TURISMO
CASE
These layers, with a maximum thickness of 45 microns, are impregnated with resin, then woven on a special machine that modifies the orientation of the fibres by 45° between layers. Heated to 120°C at a pressure of 6 bars, these materials are then ready to be processed on a CNC machine at Richard Mille’s case factory.
The case of the RM 35-02 is water resistant to 50 metres, ensured by two Nitrile O-ring seals. The case is assembled with 20 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.
FINISHING
• Bridges in hand-ground grade 5 titanium, wet-sandblasted and Titalyt® treated
• Hand-polished locking sections
• Burnished pivots
• Pinions with undercuts
• Straight line grain finish on the upper surface
• Microblasted lower surfaces
• Hand-polished sinks
• Minimal corrections applied to the wheels in order to preserve geometry and performance
OTHER FEATURES
DOUBLE-BARREL SYSTEM
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE
This permits better control of the torque applied to screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
