I'm sure everything above was correct, I just couldn't sit still long enough to read it all. The readers digest version is the movement is what actually keeps the time - it is what moves the hands in the watch.

Quartz means it takes a battery, and that is the energy of the movement.
Automatic is a self winding movement. There is a circular pendulum that winds the watch as you move your hand. Most automatic watches have about a 40 hour power reserve.
