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.
Quartz Watches. Watches with a quartz crystal movement. The most common movement in modern watches, a quartz watch is powered by an electronic movement with a tiny quartz crystal integrated into the electronics of the watch. Due to the properties of quartz, the crystal will oscillate at a practically perfect frequency when an electronic current is run through it.
