DESCRIPTION
Tell time by the atomic clock that governs ship movements, radio stations, space flights and war plans!
Watch the hands on the Zeit wall clock spin as they read the radio signals from the world's most accurate timekeeper, the National Institute of Standard and Technology's atomic clock in Fort Collins, Colorado.
The moment you put in the battery, the Zeit Wall Clock sets itself by listening for the radio signals of the NIST Atomic Clock in For Collins, Colorado. Watch those hands spin at 20 times their normal rate until the signal is picked up and the time is adjusted to accuracy with less than a one-second deviation in one million years! After that, several times each night, the clock readjusts itself based on the latest signal readings, to give you the world's most accurate time 24 hours a day. The wall clock also gives precise temperature and humidity readings. Diameter measures 12" Uses 1 AA batter (not included) lasts up to two years. Stop wondering if you really know what time it is. With the Zeit Atomic Wall Clock the U.S. official time is right on your wall!
