Atomic clocks come in all shapes and sizes, some are analog while others are digital.

By using radio waves to communicate with the central atomic clock in Colorado all atomic watches read precisely the same time as the central clock and are adjusted for yearly time changes automatically. Atomic watches allow for a level of precision that no method of time keeping has ever been able to achieve, loosing only one second of accuracy every 30 million years. A new atomic watch has to be reset for it to function properly.


Step 1

Hold down the center button which is usually on the right-hand side of the watch for 6 seconds. This activates the "Mode" setting that allows for the time to be set.

Step 2

Determine which time zone the atomic watch is set to. If the second hand is at 11:00 it is set to Eastern Standard Time, if 10:00 it is set to Central Standard Time, if 8:00 it is set to Mountain Standard Time and if 7:00 it is set to Western Standard Time.
