An automatic watch, also known as a self-winding watch or simply an automatic, is a mechanical watch where the natural motion of the wearer provides energy to wind the mainspring, making manual winding unnecessary if worn enough.[1] It is distinguished from a manual watch in that a manual watch must have its mainspring wound by hand at regular intervals.
