True to the Richard Mille spirit, grey Cermet is the fruit of painstaking research conducted by the brand, which is unrelenting in its commitment to the creation of new materials. This exclusive Richard Mille material combines the lightness of titanium and the hardness of a high-performance ceramic. Its density of 4.1 g/cm3 – less than that of titanium – and its hardness of 2,360 Vickers – almost the same as diamond’s 2,400 Vickers – make Cermet a judicious choice for use in bezels that are very exposed to scratches, while maintaining overall lightness.
Skeletonised automatic winding movement with hours, minutes, seconds at 3 o’clock, oversize date, month, flyback chronograph with minutes and countdown counters at 9 o’clock, hour counter at 6 o’clock, UTC function and variable-geometry rotor.
POWER RESERVE
Circa 55 hours (± 10%), 45 hours with chronograph running. Actual power reserve results will depend on how much the chronograph features are utilised.
BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM
The baseplate and 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, aeronautics and automotive industries.
The baseplate of the RMAC3 calibre has been optimised 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.
FLYBACK CHRONOGRAPH
By using the pusher between 4 and 5 o’clock, the running chronograph can be reset without first having to stop the mechanism. This was originally developed for pilots in order to not waste time (and therefore accuracy) from stopping, resetting and starting the chronograph whilst crossing a navigational point. While the chronograph function is activated, the hours and minutes show up the elapsed time thanks to the counter at 6 and 9 o’clock, the seconds are indicated by the central hands.
GMT FUNCTION
The RM 11-05 features a GMT hand filled with Super-LumiNova. It can be easily adjusted using the pusher at 9 o’clock.
ANNUAL CALENDAR WITH OVERSIZE DATE DISPLAY
Semi-instantaneous, placed in a blue outlined aperture under 12 o’clock with automatic adjustment for months of 30 or 31 days.
The month display is semi-instantaneous and indicated by Arabic numerals, placed between 4 and 5 o’clock.
