Swiss-Grade RMUL2 Clone Hand-Wound Skeleton Movement
The Richard Mille RM 055 Bubba Watson super clone runs on a Swiss-grade hand-wound mechanical skeleton movement engineered to match the genuine Richard Mille RMUL2 caliber in feel, frequency, and architecture. The movement operates at 21,600 vibrations per hour, winds by hand through the crown at 2 o'clock, and holds a power reserve of approximately 55 hours for over two days of autonomy off the wrist. The caliber drives the central hours, minutes, and seconds across a grade 5 titanium baseplate and bridges, the same architectural choice the genuine RMUL2 uses for shock resistance and weight reduction inside a sports tonneau case.
Accuracy, Shock Resistance and Daily Performance
Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer band that buyers expect from a Swiss-grade hand-wound build. The grade 5 titanium baseplate and bridges give the movement a strong, light core that handles shock during sport use, which is the architectural reasoning behind the genuine RMUL2 in the Bubba Watson reference. The 50-meter water resistance and the screw-down crown let the RM 055 super clone hold its seal through daily wear, hand washing, and light water contact, in line with the active-wear positioning of a golf-course sports watch.
