RM 11-05 AUTOMATIC
AUTOMATIC WINDING FLYBACK CHRONOGRAPH GMT
THE LIGHTNESS OF TITANIUM MEETS THE HARDNESS OF DIAMOND
Skeletonised automatic winding movement with hours, minutes, seconds at 3 o’clock, oversize date, month, flyback chronograph with minutes and countdown counters at 9 o’clock, hour counter at 6 o’clock, UTC function and variable-geometry rotor.
Actual power reserve results will depend on how much the chronograph features are utilised.
BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM
The baseplate of the RMAC3 calibre has been optimised for an extremely low weight/resistance ratio.
The skeletonised baseplate and the bridges were subjected to intensive and complete validation tests to optimise their resistance capacities.
While the chronograph function is activated, the hours and minutes show up the elapsed time thanks to the counter at 6 and 9 o’clock, the seconds are indicated by the central hands.
ANNUAL CALENDAR WITH OVERSIZE DATE DISPLAY
The month display is semi-instantaneous and indicated by Arabic numerals, placed between 4 and 5 o’clock.
ROTOR WITH VARIABLE-GEOMETRY
• 18K white gold weight segment
• Weight segment with 6 possible positions adjusted by screws in grade 5 titanium
• 18K white gold wings
• Ceramic ball bearings
• Unidirectional anti-clockwise winding
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.

CASE IN CARBON TPT ® AND ORANGE QUARTZ TPT ®
The production process is no less extreme than the material itself. Heating and forming such different materials together at high temperatures without adulterating their respective qualities and achieving a homogenous material is no mean feat, and one rendered all the more difficult as the composition eschews the nickel and cobalt generally used in this family of hard materials. The material is fully REACH compliant.
After years of development in specialised laboratories, Richard Mille and the Groupe IMI have succeeded in eliminating these unwanted binders, conserving only the desirable materials thanks to an innovative process that combines conventional hot-stamping associated with a series of bursts of high-voltage electrical current that make it possible to augment the kinetics of the sintering. The technique is known as flash sintering.
• Hand-polished locking sections
• Burnished pivots
• Diamond-polished sinks
• Pinions with undercuts
• Chamfered and polished by hand
• Screw slot and screws bevelled and polished for a rounded, polished tip
• Diamond-polished angles
• Circular-finished faces
• Rhodium plating (before cutting the teeth)
• Minimal corrections applied to the wheels in order to preserve geometry and performance
FREE-SPRUNG BALANCE WITH VARIABLE INERTIA
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE
This permits better control of the torque applied to the screws during assembly. These screws are unaffected by physical manipulation during assembly or disassembly and age well.
