The case uses a unique four-part structure, which is extremely difficult to make. The system is completed by adding titanium horns to the watch case assembly. After 1 hour and 40 minutes of turning processing, no less than 800 milling operations are required, which takes several hours. Processing requires nearly 11 hours of individual operations. Followed by meticulous quality control procedures, each case requires a full day. The 3 buttons, their components and the crown of the RM 60-01 require 10 days of processing time. During this period, they have undergone multiple waterproof and quality control tests, and then the entire case is manually brushed and polished. All these stages are essential for the manufacture of ergonomic Richard Mille watches. The strap is made of titanium with carbon TPT inserts.
