An automatic watch, also known as a self-winding watch, is a type of mechanical watch that harnesses the motion of the wearer’s wrist to wind the mainspring. This means that as long as the watch is worn regularly, it will maintain its power reserve without the need for manual winding.

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.
