Swiss-Grade RMAC3 Clone Automatic Flyback Chronograph Movement
The Richard Mille RM 11-03 Le Mans Classic super clone runs on a Swiss-grade automatic flyback chronograph movement engineered to match the genuine Richard Mille RMAC3 caliber in feel, frequency, and architecture. The movement operates at 28,800 vibrations per hour, winds automatically through a variable geometry rotor calibrated for everyday wrist activity, and holds a power reserve of approximately 55 hours for over two days off the wrist. The caliber drives the central hours and minutes, the small seconds at 9 o'clock, the 30-minute flyback chronograph at 4 to 5 o'clock, the oversized date at 12 o'clock, and the function selector across a grade 5 titanium baseplate and bridges, the same architectural choice the genuine RMAC3 uses for shock resistance and weight reduction.
Flyback Function, Accuracy and Shock Resistance
The flyback function lets the wearer reset and restart the chronograph in a single pusher action without first stopping the running counter, the timing tool a racing driver and a track-side observer use to clock back-to-back laps. Daily deviation holds within -4 to +6 seconds per day after factory regulation, close to the chronometer band that buyers expect from a Swiss-grade automatic chronograph build. The grade 5 titanium baseplate and bridges give the movement a strong, light core that handles shock during active wear, which is the architectural reasoning behind the genuine RMAC3. The 50-meter water resistance and the screw-down crown let the RM 11-03 hold its seal through daily wear, hand washing, and light water contact, in line with the sports-chronograph positioning of the Le Mans Classic edition.
