Clock movements are the engines, or electric motors, that manage the turning and positioning of the hands for appropriate time telling.

Clock movements were generally mechanical as well as analog, however in contemporary times they are virtually exclusively electronic, as well as either analog or electronic. In any case, the function needed boils down to the dimension of the angle subtended by each hand at every minute.

Clock movements are usually described as motors, and also the terms are practically interchangeable. The force behind a mechanical one was either a coiled spring or a hanging weight creating a flywheel to turn. To prevent "freewheeling," or runaway rotation, pendulums as well as escapement mechanisms were used, developing an oscillation that had actually an especially obtained frequency.

The modern electronic motion derives its power from a quartz crystal shaking at a details regularity that represents the geometry of the crystal. With a voltage decline applied to the crystal, it sends out a collection of pulses at the resonant regularity. Building up the variety of pulses into a digital register tracks the quantity of lapsed time.
