Performance, safety, efficiency, beauty, ergonomics: they all come together in this model. The sense of security is felt as soon as you look at this instrument thanks to the visibility of its functions, its easy-to-use controls and the accuracy of the information it displays. At 300 metres under water, there is no room for error.
A second crown is added which, when rotated once, locks the push-pieces and crown so that no function can be actuated by accidental pressure or a manipulation error. This same principle applies to the bezel, a technical miracle, which can only be manipulated by using two push- pieces to ensure total safety.
Its operating accuracy and water-tightness are the subject of countless checks throughout the fitting and assembly process of the mechanical components. The case, in three parts, requires 830 machining operations, and its absolute ergonomic perfection is achieved through manual brushing and polishing.
Round case - available in titanium, 18K white gold or red gold.
OVERSIZE DATE DISPLAY Semi-instantaneous, placed in a red outlined horizontal aperture under 12 o’clock.
MONTH DISPLAY Semi-instantaneous indicated by arabic numerals, placed between 4 and 5 o’clock.
RUNNING INDICATOR Located at 3 o’clock. Thanks to both its geometry and 2-rpm rotational frequency, it is possible to check at a glance the correct functioning of the running movement. The running indicator disc is composed of successive Superluminova and black sectors; as a result it can be easily seen during day or night.
CALIBER RMAC2 Automatic winding movement with hours, minutes, seconds, oversize date, month, flyback chronograph with minutes and seconds counter, hour counter, running indicator and adjustable rotor geometry.
ROTOR WITH VARIABLE GEOMETRY
- Arm in grade 2 titanium
- Flange in grade 2 titanium
- 6-positional adjustment via grade 5 titanium screws
- Ribs in 18k white gold, high palladium content
- Weight segment in white gold
- Ceramic ball bearings
- Unidirectional anti-clockwise winding direction
This exclusive Richard Mille design allows the rewinding of the mainspring to be adapted most effectively to the user’s activity level.
By adjusting the setting of the rib’s placement, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or slow it down when sporting activities are pursued. As a result, this invention allows the movement’s winding mechanism to be optimized.
DOUBLE BARREL SYSTEM
The double barrel system contributes to the torque stability over a longer period. This is achieved by using more rotations of the barrel, thereby reducing pressure and wear on the teeth, bearings and pivots, hence an improved long-term performance.
BOTTOM PLATE, BRIDGES AND BALANCE COCK MADE OF TITANIUM
These components are in grade 5 titanium with black PVD coating. This provides the whole assembly great rigidity, as well as precise surface flatness that is essential for the perfect functioning of the gear train.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE
Due their design, these screws offer better control of the torque applied during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
