Richard Mille – RM 030
WatchesThe RM 030 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 the brand.
The technical concept, here applied to an automatic watch, is closely linked to automotive mechanics. The innovation we hoped to achieve was to combine automatic clutching and declutching control of the winding system with a torque sensor, thus ensuring an ideal degree of spring tension for the perfect supply of torque to the movement.

Description
The caliber RMAR1, with 40 jewels and beating at 4Hz, has a 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.
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 complex 5 axis machine. For each case, the name “Richard Mille” engraved on the back of the case situated on the inside curve requires 45 minutes.
