What does self-winding mechanical movement mean?

Often referred to as self-winding, an automatic watch is a mechanical watch that harnesses the kinetic energy produced by the natural movement of the wearer's wrist. The spring is automatically wound by the natural movements of the wearer's wrist. The power reserve usually ranges from 36 to 80 hours, so if you don't wear this type of watch for several days it may stop: just put it on your wrist and the watch will work again. One of the benefits of mechanical watches is that by avoiding the use of batteries used for quartz movements, you can protect the environment and, with proper maintenance, a mechanical watch will often last for decades.
