ENHANCING MICROMECHANICAL ACHIEVEMENTS

This model represents real progress in terms of performance. To develop a declutching rotor system – a dynamic continuation of the torque sensor already used in our tourbillon watches – had long been a dream of Richard Mille. The technical concept which in this case is applied to an automatic watch is closely linked to automotive mechanics.
The innovation we hoped to achieve was to combine the automatic clutching and declutching control of the winding system with the torque sensor, thus ensuring an ideal degree of spring tension for a perfect torque effort. This system is similar to the optimum rotation speed required by the engine of a racing car and guarantees the superlative functioning of the watch.

Main characteristics

DECLUTCHABLE ROTOR. The torque sensor activates the winding function as soon as the tension in the mainspring no longer provides optimum torque.
Available in titanium, 18K red and white gold.

BOTTOM PLATE, BRIDGES AND BALANCE COCK MADE OF TITANIUM RM030

These components are in grade 5 titanium with Titalyt® treatment. This provides the whole assembly great rigidity, as well as precise surface flatness, which is essential for the perfect functioning of the gear train. The skeletonized baseplate was subjected to separate and extensive validation tests to insure optimal strength requirements.

CASE RM030

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 specification, 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. For example, a casing ring is no longer used and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by 4 titanium screws. Features such as these are evidence of uncompromising workmanship. The case of the RM 030 requires 86 swaging operations including 49 striking, before cutting and milling phases for the three main components (bezel, middle case, back). Machining requires 20 hours for the settings and it takes 30 hours for a kit programming. The empty case requires more than 255 tooling operations and more than 5 hours of glazing and polishing for the final phase. The complex shape of the case is obtained thanks to a 5 axis machine. For each case, the name “Richard Mille” engraved on the back of the case situated on the inside curve requires 45 hours. The tripartite case is water resistant to 50 meters, ensured by two Nitril O-ring seals. The case is assembled with 20 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel.

DECLUTCHABLE ROTOR RM030

The winding of an automatic wristwatch is accomplished by a small turning rotor, silently driven as a result of the physical movements of the wearer. These rotations of the rotor provide energy to the winding barrel, which reaches its optimal point once it is fully wound. After this point, overwinding can easily occur and needs to be avoided. This is traditionally achieved through the use of a sliding flange that allows the spring to slip, thus avoiding the movement becoming overwound. However, this traditional system allows the build-up of harmful debris inside the winding barrel as the flange releases the excess energy of overwinding during longer periods, especially when a person is particularly active. This in turn can severely affect chronometric results. To avoid such adverse conditions, Richard Mille took 4 years to develop the concept and design of a rotor that declutches automatically. With this system, the winding barrel is automatically disconnected from the rotor’s winding mechanism at the moment when the spring is fully wound. Additionally, this new mechanism is linked to the power reserve indicator to provide an optimal winding control. This allows both the movement and the oscillator to work with the best ratio of constant torque/power to provide the best chronometric performance. Functioning: When the power reserve reaches 50 hours, the rotor is declutched automatically thanks to a specially developed gear system. As a result, the rotor is disengaged from winding the barrel. Conversely, when the power reserve decreases to 40 hours, the rotor is automatically clutched and the watch starts the winding phase until the indicator reaches 50 hours. It is possible to check theses phases thanks to the rewinding indicator located at 12 o’clock. It keeps the user informed whether the rotor is operating in winding phase (on) or is disengaged (off).

Characteristics

FREE SPRUNG BALANCE WITH VARIABLE INERTIA
This type of balance wheel represents the ultimate in innovation. 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.

DOUBLE BARREL SYSTEM
The double barrel system helps improve torque stability over a longer period.
This is achieved by utilizing more turns of the barrel, thereby reducing pressure and wear on the teeth, bearings and pivots, resulting in improved long-term performance.
