When purchasing an automatic wrist watch, one needs to consider how it works. This consideration could possibly lead to the perfect selection. The available watch options on the market are the battery operated watches, winding watches, and the automatic or self-winding wrist watches.

Since an electric watch operates off a good battery and a winding watch operates based on a person winding it up, this leaves the question of how an automatic wrist watch works. The simple explanation is that it winds itself. To understand this concept, instead of thinking about a small winding rod that a person controls, think about a metal plate that is spinning around inside of the watch itself. The ingenious design of the automatic watch incorporates this concept. They have some type of a metal disc inside that weighs slightly more than the rest of the internal mechanisms. As a person moves about in their daily activity, their arms are constantly in motion. As the disc inside of the watch turns it winds a tiny spring and keeps it coiled which in turn stores energy to keep the watch going. So in effect, as long as a person is in motion, the watch is winding itself and keeping good time. This leads to the question of how it keeps time if a person takes the watch off for a long period.

Since the watch is constantly in motion and the spring is wound very tightly at the end of a normal day, the spring supplies enough energy to keep time for at least a day, often longer. In the more modern automatic wrist watch, designers have included a tiny battery to make up for the times when a watch is not in motion. The battery will eventually run out, but this can take as much as eight to ten years in the nicer models.
