What is Atomic Radio Control?

Atomic radio control watches are the most precise time keeping devices in the world. They keep time to the ac- curacy of more than 1 second in one million years. Until recently, the atomic watches were only found in labo- ratories and special institutions and were very large and expensive. When various governments began to broadcast atomic, electronically encoded signals with their own na- tional time, the accuracy of the atomic radio control watch became available to the general public. Recent technology enabled this process to be miniaturized and to be offered at a reasonable cost.

The Global Atomic Watch takes it one step further. Until the development of this type of watch, atomic watches were able to receive and decode signals from only one transmitter.
