This exclusive Richard Mille design makes it possible to effectively adapt rewinding of the mainspring to the user’s activity level, in sporting or non-sporting environments. By adjusting the six-position rib, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or to slow it down during sporting activities.

Details recalling automobile racing abound in the RM 11-03. The grade 5 titanium crown borrows the design of competition wheel rims and tyre treads. The grooved pushers, machined of the same material, recall the surface of pedals, and have covers made of another material as ubiquitous as titanium in Formula 1: Carbon TPT®.
The tripartite case of the RM 11-03 is water resistant to 50 metres, ensured by two Nitrile O-ring seals. The case is assembled using 20 spline screws in grade 5 titanium and abrasion-resistant washers made of 316L stainless steel.
