RM 037
SOPHISTICATED, REFINED, DARING
Our objective for this model was to construct a synthesis, to bring together all the experience we have gained since the creation of the brand in one watch. And it had to be spectacular, both technically and aesthetically, with finishing also of an exceptional level.
Extreme technicity, sophistication and hand finishing in the grand tradition of Swiss watchmaking make the RM 037 an exceptional piece which exemplifies the innovative style that is Richard Mille’s hallmark.
CALIBRE CRMA1
Skeletonised automatic-winding in-house movement
Hours, minutes, variable-geometry rotor, oversize date and function selector
Power reserve: around 50 hours (± 10%)
Dimensions: 52.20 x 34.40 x 12.50 mm
BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM
Microblasted grade 5 titanium with an 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. The bridges are also in grade 5 titanium, microblasted and electroplasma treated.
The skeletonised baseplate and the bridges were subjected to separate and extensive validation tests to ensure optimal strength requirements.
OVERSIZE DATE DISPLAY
Semi-instantaneous, horizontally placed under 12 o’clock, functioning via two skeletonised calendar discs over a white field.
FUNCTION SELECTOR
The function selector shows Richard Mille’s passion for mechanical innovation. A push-button makes it possible to select the winding, neutral and hand-setting functions with a simple push. A hand displays the selected function: W (Winding) – N (Neutral) – H (Hand Setting).
With this special gear system, stressful forces placed upon the crown are minimised, and any possible interference of the crown’s functions with the movement is made impossible.
MOVEMENT CHARACTERISTICS
Movement dimensions: 28.00 x 22.90 mm
Thickness: 5.79 mm
Number of jewels: 25
Balance: CuBe, 4 arms and 4 setting screws, moment of inertia 7.5 mg•cm2, angle of lift 50°
Frequency: 28,800 vph (4 Hz)
Balance spring: AK3
Shock protection: INCABLOC 908.22.211.100 (transparent)
Escapement wheel jewels: Rubifix (transparent)
PATENTED STEM-CROWN CONSTRUCTION
Created from grade 5 titanium, red gold or white gold, with O-ring seal and collar in Alcryn®, this crown fully guarantees the integrity of the movement protecting the mechanism from external influences, since it does not use a classical crown attachment that penetrates to the movement’s heart.
The result is a crown that is virtually impossible to dislodge, yet is easily inserted and removed in the skillful hands of the watchmaker when needed; a longsighted view that is typical of the brand’s philosophy.

Other features
FAST-ROTATING BARREL (5 hours per revolution instead of 7.5 hours)
This type of barrel provides 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.
FREE-SPRUNG BALANCE WITH VARIABLE INERTIA
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shocks or during movement assembly or disassembly, hence better chronometric results over time.
The regulator index is eliminated and a more accurate and repeatable calibration is possible thanks to 4 small, adjustable weights located directly on the balance.
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.
