Overview
5N red gold case
Richard Mille produced the RM 65-01 in Carbon TPT® and in combinations using 5N red gold. The photograph shows the red gold execution: a gold tonneau case with black bezel screws, a red inner flange, green and red pusher caps and a black rubber strap, with the model’s colour-coded displays visible through the skeletonised dial.
The calibre is unchanged. The RMAC4 is a skeletonised automatic split-seconds chronograph developed with Vaucher Manufacture Fleurier over five years, running at 36,000 vph with a rapid-winding pusher, a function selector integrated into the crown and a variable-geometry rotor.

Design and engineering
- Calibre RMAC4Skeletonised automatic winding movement with hours, minutes, seconds at 6 o’clock, date, split-seconds chronograph with a 30-minute counter at 3 o’clock and a 12-hour counter at 9 o’clock, function selector, rapid winding and variable-geometry rotor. It measures 31.78 × 29.98 mm by 8.69 mm thick, on 51 jewels at 36,000 vph (5 Hz), with around 60 hours (± 10%) of power reserve without the chronograph running.
- Split-seconds architectureTwo six-column wheels with a vertical clutch. The 5 Hz frequency allows elapsed times to be read to a tenth of a second. Richard Mille records shock and drop simulations, accelerated ten-year ageing of the functions, water-resistance testing and magnetic field trials for the chronograph.
- Rapid windingThe pusher at 8 o’clock rearms the barrel directly, without the crown; 125 presses take it to a full charge. Richard Mille specifies it for restarting a watch that has stopped.
- Function selector in the crownSelects the winding, date and hand-setting positions as the crown is pulled out — which Richard Mille records as a first on one of its automatic watches.
- Baseplate and bridgesGrade 5 titanium — 90% titanium, 6% aluminium, 4% vanadium — wet sandblasted with PVD and electroplasma treatment.
- Variable-geometry rotorThe oscillating weight segment can be reconfigured to change the rotor’s inertia, and so the winding yield, according to how active the wearer is.
- Colour codingThe dial is coded by function rather than decorated: yellow for the time, green for the date, orange for the chronograph displays, red for winding and blue for the split-seconds hand.
