Richard Mille develops its first flyback chronograph inhouse for the new RM 72-01


Richard Mille has installed its first flyback chronograph, entirely developed and designed by the brand, in a new RM 72-01 that launches this week.

The watch follows the rule of three, which influences everything from design to dance, with three subdials, only three numbers on the dial — three, eight and eleven — and three timescales: blue for seconds, orange for minutes, green for hours.

The Calibre CRMC1 flyback chronograph movement, which Richard Mille says took 30 months to develop, has a double oscillating pinion mechanism and double-clutch chronograph.


“This pinion, which can enmesh or withdraw from the gear teeth, has been twinned. There’s now one for the minutes and another for seconds. This system is thinner than a vertical clutch, which would be hard to fit into the heart of the movement,” explains Salvador Arbona, Technical Director for Movements.

As a result, the chronograph function has little impact on the 50 hour power reserve.

“We completely suspended torque transfer, separating the chronograph from the minute and hour display — a new achievement in watchmaking,” Mr Arbona adds.
