Atomic Watches automatically set themselves to radio signals linked to the U.S. Atomic Clock so you'll always know the exact time. Precision time is achieved by the watch's built-in receiver that tunes in daily to the National Institute of Standards and Technology's Atomic Clock in Boulder, CO. Accurate to within a ten billionth of a second, the Atomic Clock sends the signal directly to the watch, keeping you on time, every time.
