Richard Mille RM11-04 Roberto Mancini
Skeletonised automatic winding movement with hours, minutes, seconds, oversize date, month, flyback chronograph with central minutes counter and variable-geometry rotor.
Circa 55 hours (± 10%), 45 hours with chronograph running.
Actual power reserve results will depend on how much the chronograph features are utilised.
The baseplate and the bridges are crafted of grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% grade 5 titanium, 6% aluminium and 4% vanadium. This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautical and automobile industries. The baseplate of the calibre RMAC3 has been optimised to for an extremely low weight / resistance ratio.
The skeletonised baseplate and the bridges were subjected to intensive and complete validation tests to optimise their resistance capacities.
The flyback chronograph dial displays match time on the basis of two 45-minute halves, and up to 15 minutes of stoppage time. Pressing the pusher at 4 o’clock once actuates the flyback function and repositions the hand at 12 o’clock, ready to start the second half. If extra time is awarded, the flyback function can be reactivated so that the watch shows the 15 minutes of extra match time and up to 5 minutes of stoppage time.
