IN-HOUSE DESIGNED CALIBER

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.

Main characteristics

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.

01
CALIBER CRMA1
Skeletonised automatic movement with hours, minutes, adjustable rotor geometry, oversize date and function selector.

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.

02
CALIBER CRMA1
Skeletonised automatic movement with hours, minutes, adjustable rotor geometry, oversize date and function selector.

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).

03
CALIBER CRMA1
Skeletonised automatic movement with hours, minutes, adjustable rotor geometry, oversize date and function selector.

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.

Main characteristics

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.

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 316L stainless steel.

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.

NEWLY DESIGNED FLAT HEAD MOVEMENT SCREWS IN GRADE 5 TITANIUM RM037

Richard Mille as utilized the best of modern micro mechanical engineering in the use of special flathead screws in the caliber CRMA1. These unusual screws with their 6 holed heads are based upon the snake-eye screw concept principally used in the assembly of parts that require extremely exact torque to be applied. For specific movement parts, these screws provide secure fixation that still allows for rotational movement of the date and function selectors.

Characteristics

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.
