WATCHERY GLOSSARY
Automatic Watch/Automatic Movement/Automatic Winding
Also called “self-winding,” a watch with automatic movement needs no battery. The mechanism winds itself by the motion of the watch wearer’s arm. Most automatic watches have up to 36 hours of power reserve. If an automatic watch is not worn for a day or two, it will wind down and need to be wound by hand to get it started again. Typically, an automatic watch is more expensive than a quartz watch.
