Overview
Full red gold case
The red gold execution of the RM 72-01: a tonneau case in 5N red gold with black pushers and a black crown, over the skeletonised CRMC1, on a black rubber strap.
At launch Richard Mille offered the reference in grade 5 titanium and 5N red gold, with the two ceramic executions following.

Design and engineering
- Calibre CRMC1Skeletonised movement with automatic bidirectional winding, hours, minutes, small seconds, date, flyback chronograph, function indicator and stop seconds. It is 6.05 mm thick, comprises 425 components, runs on 39 jewels at 28,800 vph (4 Hz), and provides around 50 hours of power reserve regardless of how much the chronograph is used.
- Flyback chronograph with two oscillating pinionsPatented by Richard Mille and the first chronograph to use two oscillating pinions. The pinions are mounted on rockers actuated by a six-column wheel, and draw power directly from the barrel rather than through the timekeeping gear train, so that the chronograph’s three counters are supplied at the point where torque is greatest and the display is disengaged from the chronograph’s seconds wheel. Richard Mille specifies the arrangement as thinner than a vertical clutch and less sensitive to disturbance.
- Baseplate and bridgesGrade 5 titanium — 90% titanium, 6% aluminium, 4% vanadium — microblasted with a grey electroplasma treatment.
- Platinum rotorBidirectional and compact, allowing efficient winding within the movement’s height.
- Fast-rotating barrelOne revolution every five hours, which Richard Mille specifies for reduced periodic internal mainspring adhesion and smoother power delivery.
- Free-sprung balanceSpecified for reliability through shock and through movement assembly and disassembly.
- Tripartite case38.40 × 47.34 × 11.68 mm, water-resistant to 30 m via three nitrile O-ring seals, assembled with 20 grade 5 titanium spline screws and abrasion-resistant 316L stainless steel washers.
