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.

The first self-winding mechanism was invented for pocket watches in 1770 by Abraham-Louis Perrelet, [57] but the first "self-winding", or "automatic", wristwatch was the invention of a British watch repairer named John Harwood in 1923. This type of watch winds itself without requiring any special action by the wearer.
[citation needed] An automatic timepiece needs to be worn for about 10–15 hours before it is fully wound. [citation needed] The power reserve indicator displayed on the watch with automatic- winding movement shows how long a watch will function when not worn. On a manual winding watch, it shows the time left until the watch needs winding.
