The RM 35-03 Automatic Rafael Nadal, the fourth watch in the RM 035 Collection, inaugurates a new winding mechanism christened the ‘butterfly rotor’. This patented invention hands direct control over the automatic movement’s winding to the wearer. It’s a brand new way to stay in touch with your watch under all circumstances.

Manufacturing these components in grade 5 titanium with black PVD and electroplasma treatments confers great rigidity on the entire assembly, as well as precise surface flatness, essential for perfect functioning of the gear train.

The butterfly rotor is made up of two weights in grade 5 titanium and metal. In their initial position, the weights cause a radial displacement of the center of gravity, generating the necessary torque to wind the barrel. With a simple pressure on the pusher at 7 o’clock (SPORT MODE), a gear train dedicated to the rotor deploys the two weights at 180°. The center of gravity is then brought back to the center, bringing the rotor into balance, canceling its winding power and thus any excessive winding of the calibre.
