The Richard Mille RM 75-01 has the following unique features:



Floating Tourbillon: Located at 6 o'clock, its unique feature is that the tourbillon frame adopts a design without an upper bridge, presenting a floating lightness effect, which not only provides excellent visibility, but also further improves the shock resistance and the reliability of the movement assembly and disassembly, ensuring more accurate timing over a long period of time. In addition, the regulator fine-tuning system is eliminated, and the inertia of the rotor can be adjusted more accurately and stably through 4 adjustable weights placed directly on the balance wheel.

Fast-rotating floating barrel: It takes 5.2 hours to rotate one circle, which greatly reduces the mainspring adhesion phenomenon and enhances performance. At the same time, it provides an ideal power reserve, performance and stability ratio, forming an excellent mainspring delta curve.

Gradual rebound function barrel pawl: when winding, a considerable energy gain (about 20%) can be obtained, especially at the beginning of winding, and it can also make the tension distribution inside the mainspring barrel more uniform.

Involute tooth profile design: The central involute tooth profile design of the winding barrel teeth and pinion can provide an ideal 20° pressure angle, which can optimize gear transmission efficiency, offset gear meshing deviation, ensure excellent torque transmission, and greatly improve movement performance.
