The Richard Mille RM 052 Tourbillon Skull is a limited-edition timepiece that seamlessly integrates a skull motif into its design, symbolizing liberty and nonconformity. The watch features a manual-winding tourbillon movement with hours and minutes, housed in a tripartite case crafted from grade 5 titanium. The baseplate and bridges are skeletonized to form a skull, with the upper and lower jaws holding the ruby of the tourbillon cage. The back of the skull serves as the movement's center bridge, and four bridges inspired by crossed bones connect the movement to the case. This model is a true expression of haute horlogerie, combining extreme technique, high performance, and meticulous hand-finishing.
