On Clock Movements and Motors Clock movements and electric motors are the core of any type of watch. Clock activities as well as electric motors may be mechanical or electronic, analog or digital, but they all figure out the angle subtended by each of the hands at any kind of given moment. Having existed for centuries in one form or another, these interesting tools possess a rich background. Clock electric motors and also motions are in fact compatible terms describing the same point, though "movement" is a profession term while laypersons tend to favor "electric motor." Originally they were strictly mechanical, using the force of a hanging weight or coiled spring to revolve a flywheel. Pendulums and also escapements transformed the turning into an oscillating motion with a specifically derived regularity.
