The RM 17-01 Tourbillon is a new understanding of the RM 017, highlighting its very elegant and technic calibre through sleek, elegant lines achieved by the characteristic tonneau-shaped case. Symbolizing the Haute Horlogerie values of both tradition and excellence, the calibre RM017 integrates all our passion for mechanical innovation, illustrated there by the function and power reserve indicators or even the abundance of titanium in its heart.
Iconic signature of Richard Mille watches, the Carbon TPT® tonneau-shaped case brings the calibre RM017 to new spheres.
Sportier, it is suitable for all situations while preserving the elegance of his high-end finished movement.
Its tonneau-shape case represents an uncompromising approach, with extensive attention to all details of the case design with numerous machining operations required for the three main components (front bezel, back bezel and caseband).

Indicated by a scale located on a scale at 2 o’clock, the power-reserve indicator shows the number of hours of energy left in the mainspring before the watch must be wound again.
In a manner similar to a car’s gearbox, the function indicator identifies the winding, neutral and hand-setting positions as the crown is pulled out. A hand located at 4 o’clock indicates the current position.

The design and execution of the watch demonstrate a holistic approach to conception of the movement, case and dial. As a result, everything has been constructed according to extremely rigorous specifications, in the manner of the analytical engineering methods used in the design of Formula 1 racing cars, where the chassis and the engine are developed in complete harmony. For example, a casing ring is no longer used, and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by grade 5 titanium screws. Features such as these are evidence of uncompromising workmanship.
The tripartite case is water resistant to 50 metres, ensured by 2 Nitrile O-ring seals. The case is assembled with 12 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.
