One of the purest executions of Richard Mille's design philosophy, the RM005 was the legendary brand's fifth collection. Introducing a series of firsts, the RM005 features RM's first automatic movement with the brand's first variable-geometry winding rotor. Customisable to the owner's lifestyle, the RM005 can convert various inertial inputs to the power reserve depending on the wearer's level of activity. For strenuous exercise, where the watch may be swung a lot, it can be reduced to protect the movement or increased, should the activity be relatively gentle. With a semi-instantaneous date-change, skeletonised PVD-treated movement and titanium construction, this timepiece is still a perfectly modern watch, even if it is neo-vintage considering Richard Mille's surprising youth as a brand.
