The beating heart of every automatic watch is its movement, a complex system made up of tiny components that provide the watch's timekeeping functionality.  Unlike conventional quartz (battery-powered) watches, automatic watches are powered by the kinetic energy of the wearer's wrist and can easily be identified by the smooth-sweeping motion of the seconds hand. If you are having trouble deciding which movement to go for, this guide should help answer some of your questions.
