TECHNICA SPECIFICATIONS OF THE RICHARD MI E RM 037 ADIES
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.

FAST ROTATING BARREL (5 hours per revolution inste d of 7.5 hours)
This type of barrel has the following advantages:
- The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance,
- Provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.
NEWLY DEVELOPED GEAR TEETH PROFILE
The entire going train of the watch, the primary transmitter of power throughout the movement, utilizes a special
profile for the teeth of the wheels. Developed specifically for the caliber CRMA1, the wheels use a 20° pressure angle.
This system equalizes any discrepancies that might arise between the centers of each wheel, for instance during thermal
changes and normal use, and promotes an excellent transmission of torque to the balance wheel, thus supporting
excellent chronometric characteristics.
OVERSIZE DATE DISPLAY
Semi-instantaneous, horizontally placed under 12 o’clock, functioning via two skeletonised calendar discs over a white
field. The date can be easily corrected via the pusher located at 10 o’clock.
FUNCTION SELECTOR
A push-button located at 4 o’clock allows one to select the winding, neutral and handsetting functions with a simple push
in a manner similar to a car’s gearbox. An aperture located at 4 o’clock shows the function selected: W (Winding) -
N (Neutral) - H (Handsetting).
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE MOVEMENT
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected
by physical manipulation during assembly or disassembly and age well.

CASE
The design and execution of the watch demonstrates a complete conceptual approach to the movement, case and dial.
As a result, everything has been constructed according to an extremely rigorous specifications, in the manner of the
analytical engineering methods used in the design of Formula 1 racing cars where the chassis and the engine are
developed in complete harmony.
The in-house CRMA1 is highlighted by the combination of unique materials such as red gold for the caseband and TZP
black ceramic for the bezel and the caseback. It is particularly resistant to knocks and scratches and undergoes a long
production process which results in a final matt surface finish. The caseband is in satin 5N red gold with polished pillars.
The RM 037 is available in TPZ black ceramic, in ATZ white ceramic and in white or red gold.
The three-part case is rendered water resistant to 50 meters ensured by two Nitril O-ring seals. It is assembled using
20 grade 5 titanium spline screws and abrasion-resistant washers in 316 stainless steel.
NEW PATENTED STEM-CROWN CONSTRUCTION
This designed crown allows the integrity of the movement to be fully guaranteed and protected from external influences,
since it does not use a classical crown attachment going into the depth of the movement’s heart. The result is that the
crown is virtually impossible to
dislodge and yet it is easily inserted and removed under the skillful hands of the watchmaker when needed; a typical view
towards longevity that typifies the brand’s philosophy. An ideal solution for the long-term protection of the movement.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE CASE
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected
by physical manipulation during assembly or disassembly and age well.
