Richard Mille RM 70-01 : CALIBRE RM70-01– Manual winding tourbillon movement with hours, minutes, power-reserve indicator and mechanical odometer.
The pusher at 2 o’clock can select any of the five rollers linked to the odometer, whose readout is visible in a titanium window. Once a roller has been selected, pressing the pusher at 10 o’clock advances the roller by one. The only effort required of the user is to add the day’s distance to the previous total.
The mechanism itself, however, is much more complicated. The first pusher enables one of the five rollers to be selected. Execution is confirmed by the perfect alignment of two yellow arrows. The second pusher incrementally rotates the roller, which automatically blocks thanks to its carry mechanism. To avoid accidental manipulations, the complication has been fitted with a neutral position (N). A spring-lock ensures that the selection fork is lined up straight, with an arrow at 2 o’clock pointing to N providing visual confirmation that the mechanism is locked.
