Self-winding
In these timepieces, the mainspring is wound by a rotor, which is set in motion by wrist movements. Patek Philippe rotors are crafted from 21K or 22K gold because the high specific gravity of the precious metal optimizes the kinetic energy yield. Patek Philippe has been manufacturing self-winding movements since 1953 and has developed a number of high performance mechanisms, many of which form the basis of complicated movements that delight the most discerning watch lovers.
