Overview
Red gold and Carbon TPT® case
Richard Mille produced the RM 65-01 in Carbon TPT® and in gold and Carbon TPT®. This is the red gold execution: a red gold bezel with a Carbon TPT® caseband, black bezel screws and a red inner flange.
The RMAC4, the culmination of some five years of development, is a skeletonised automatic split-seconds chronograph running at 36,000 vph, with a rapid-winding pusher at 8 o’clock, a function selector operated by the pusher at the centre of 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 architectureThe latest-generation split-seconds mechanism uses a 6-column wheel for optimised simultaneous movement, maximal function locking and greater adjustment durability. The 5 Hz balance can measure accurately to 1/10th of a second. The chronograph was tested through shock and drop simulations, accelerated 10-year ageing of all its functions, waterproof tests and magnetic field resistance trials.
- Rapid windingIn addition to automatic winding and winding with the crown, pressing the pusher at 8 o’clock fully rearms the barrel — intended for quickly restarting the watch if it has not been worn for a long time.
- Function selector in the crownThe pusher at the centre of the crown moves through the Winding, Date and Hand Setting functions; the hand at 4 o’clock indicates W, D or H accordingly.
- 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.
