Video of the rotor turning in an automatic wristwatch having a glass back, when the watch is moved by hand. 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]
A self-winding or automatic watch is one that rewinds the mainspring of a mechanical movement by the natural motions of the wearer's body. 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 ...

The hand-winding movement of a Russian watch. A mechanical watch is a watch that uses a clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio watches, which are quartz watches synchronized to an atomic clock via radio waves.
Automatic quartz is a collective term describing watch movements that combine a self-winding rotor mechanism [1] (as used in automatic mechanical watches) to generate electricity with a piezoelectric quartz crystal as its timing element. Such movements aim to provide the advantages of quartz without the inconvenience and environmental impact of ...
Illustration attached to Meylan's automatic module patent [6]. With the original patent for self-winding watches set to expire in the early 1930s, [3] Meylan (founder of Glycine but no longer affiliated with the company) began working on his own self-winding mechanism and formed the company Automatic E.M.S.A. (Eugène Meylan Société Anonyme).
The movement of a digital watch is more commonly known as a module. In modern mass-produced clocks and watches, the same movement is often inserted into many different styles of case. When buying a quality pocketwatch from the mid-19th to the mid-20th century, for example, the customer would select a movement and case individually. Mechanical ...
