The objective for the RM 037 is to construct a synthesis, to bring together all the experience Richard Mille 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. Beneath its highly contemporary appearance, the watch respects all the canons of high-end watchmaking.
This new caliber, starting from a blank page in order to insure a fresh approach, was designed entirely in house at the Richard Mille Watches facility in Switzerland.
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.
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).
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.
CALIBER CRMA1 Skeletonised automatic movement with hours, minutes, adjustable rotor geometry, oversize date and function selector.
FAST ROTATING BARREL (5 hours per revolution instead 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.
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.
In carbon fiber; index points filled with approved luminous material.
