RM 031 High Performance Chronometer

The Richard Mille brand only focuses on the pursuit of performance. This approach led the RM engineers to use materials with extraordinary physical characteristics from fields far removed from watchmaking, such as aviation, the automobile industry, and cutting-edge electronics. The RM 031 High Performance Chronometer is a timepiece that fuses traditional watchmaking techniques with cutting-edge ideas. It is the outcome of a dedicated effort to make the most consistent mechanical calibre in the world, despite its conventional design.
