ABSOLUTE BEAUTY AND PURITY
The RM 017 Tourbillon is the first and only rectangular case shape in the tourbillon range, continuing the development of the rectangular case first launched with the RM 016.
Its profile is among the thinnest of the collection, representing a new visual incarnation suitable for all occasions with the same wrist-fitting curvature and taper typical of all Richard Mille creations.

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.
