Self-winding
Self-winding mechanical movements, known as "automatic movements," wind up the mainspring via a rotor powered by wrist motion. Our rotors, crafted from 21K or 22K gold, utilize the precious metal's high density to enhance kinetic energy efficiency. Patek Philippe has been crafting self-winding movements since 1953, developing numerous high-performance mechanisms that serve as the foundation for complex movements admired by discerning watch enthusiasts.
Manual winding
Mechanical movements with manual winding, commonly called "manual movements," are powered by hand-turning the crown. The mainspring slowly unwinds, driving the gears at the heart of the watch. Whether ultra-thin, simple or complicated, these manually wound movements are highly valued by enthusiasts of traditional watchmaking.
Quartz
As a pioneering company committed to our philosophy of excellence, we were among the first watchmakers to explore electronic timekeeping in 1948. Our electronic quartz movements are crafted with the same meticulous attention to quality as our mechanical movements, ensuring that every plate, bridge, and cog meets our extremely demanding standards.
