In response to this motion, a rotor turns and winds the watch's mainspring so that it twips accurate time. Each movement of your arm winds the spring the tanyest bit, but since you move your arm so much it keeps the watch wound easily. The spring in the watch stores enough energy to keep the watch going for 36 hours, If an watch is not worn for a day or two, it will need to be wound by hand to restart again.
