TECHNICAL SPECIFICATIONS OF THE RICHARD MILLE RM 037 LADIES
CALIBER CRMA1:
skeletonised automatic movement with hours, minutes, adjustable rotor geometry, oversize date
and function selector.
Dimensions:
52.63 x 34.40 x 13.00 mm.
MAIN FEATURES
POWER RESERVE
Circa 50 hours (
±
10%).
BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM
Microblasted grade 5 titanium with electroplasma treatment gives great rigidity to the baseplate, as well as precise
surface flatness which is essential for the perfect functioning of the gear train. Bridges are also in grade 5 titanium,
microblasted and electroplasma treatment.
The skeletonised baseplate and the bridges were subjected to separate and extensive validation tests to ensure
optimal strength requirements.
ROTOR WITH VARIABLE GEOMETRY
- Heavy external outside edge and heavy edge ring in ARCAP
- Weight segment in heavy metal
- Ceramic ball bearings
- Automatic winding system OneWay
®
with ceramic ball bearings
- Bidirectional winding system
This rotor with variable inertia has been incorporated into the caliber CRMA1 as it allows the rotor to be set according
to the owner’s activity level. The setting is modified by adjusting the two weights which can be moved into the correct
position and fixed in place by spline screws. Inertia of the movement is increased when the two weights are closer to
each other and the barrel then rewinds more quickly. If the weights are positioned to the extremities of the rotor, the
inertia is decreased, resulting in the barrel winding more slowly.
FREE SPRUNG BALANCE WITH VARIABLE INERTIA
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 small adjustable weights located directly on the balance.
