Skeletonized automatic-winding tourbillon movement having hours, minutes, and a rotor with changing shape. The 18K 5N red gold baseplate and 18K 3N yellow gold bridges of the RM 74-02 Automatic Winding Tourbillon are painstakingly micro blasted and bevelled. To enhance their resistance capacities, the skeletonized baseplate and bridges underwent extensive and thorough validation tests.
