The RM 35-03 Automatic Rafael Nadal inaugurates a new winding mechanism christened the butterfly rotor.The RM 35-03 is the first Watch watch to contain the new RMAL2 automatic movement thatfeatures a Sport Mode pusher that adjusts the two-position automatic rotor shape. One position is a more normal half-disc shape that offers the most winding efficiency and is thus ideal for most wearing scenarios. The Sport Mode position splits the rotor apart and forms the butterfly shape that more evenly distributes the weight. This puts the rotor into a state less likely to spin and. thus. put stress on the movement. The watch is crafted in a blue carbon case measuring 43 x 49mm and comes on a white rubber strap.
