Automatic watch. An automatic or self-winding watch is a mechanical watch in which the mainspring is wound automatically as a result of the natural motion of the wearer to provide energy to run the watch, making manual winding unnecessary. A mechanical watch which is neither self-winding nor electrically driven is called a manual watch. Most mechanical watches manufactured today are self-winding.
M Philippe added a knurled knob attached to a rod (or stem), which was permanently connected to the spring mechanism, making it much easier to wind. Hence stem-winding watch or stem-winder (this was the US name: in Britain it was called a keyless watch). The idea of winding a watch at all now seems odd to most people, accustomed as we are to possess one with a battery or other energy-providing mechanism that doesnât require us to think about it from month to month.
