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.
This piece can be accompanied by a rich variety of straps and more specifically by two gold straps: either full metal link or open link.
RM 037 Automatic Winding
CALIBRE CRMA1
Skeletonised automatic-winding in-house movement
Hours, minutes, variable-geometry rotor, oversize date and function selector
Bridges and baseplate in grade 5 titanium
Power reserve: Circa 50 hours (± 10%)
Dimensions: 52.63 x 34.40 x 13.00 mm
GEM-SET CARBON TPT®
At the slightest wrist movement, all eyes are riveted by a striking contrast between the sparkle of clear diamonds and the matt carbon contour that adorn both of these automatic timepieces.
Setting gemstones in Carbon TPT® is a new adventure for the brand. Unlike gold, which can be worked directly with tools to create the prongs that will hold the diamonds, the hardness and resistance of Carbon TPT® mean special CNC machines for milling equipped with diamond tools are required to perform the mitraillage involved in a pavé setting.
Hand-polished prongs in red or white gold are produced separately and then inserted around the many 0.25mm bearings destined to firmly contain as many as 250 diamonds in the case of an RM 037 Full Set model. The perfectly flush surface of each creation bears witness to an absolute mastery of this art.
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)
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.
PATENDED 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.
