Atomic clock movements are accurate to 1 billionth of a second. Both quartz movements contain a
miniaturized radio receiver that monitors a low frequency time signal that broadcasts from Fort Collins, Colorado. The atomic radio signal enables the movement to self-correct every day so it always shows the exact time according to the national time standard. The movement is capable of running traditional hands and is equipped with a special antenna designed for increased reception sensitivity.
