They don't use radio activity and can be used by anybody just like any other wrist watch without any precaution or fear of radiation. The basic principle of its working is similar to the radio clock which display the time based on the signals received from a transmitter connected to an atomic clock. When compared with mechanical and electronic or digital watches, they are convenient as they adjust automatically to and from daylight. A time setting in an atomic watch is auto adjusted with the help of the synchronization signal originating from a transmitter like WWVB (a special time signal radio station near Fort Collins, Colorado, USA). The frequency of transmission is 60 kHz. These signals are received by an antenna in the atomic watch which is encoded by an internal program, which again is decoded to display the most accurate time ever available in any watch. In order to maintain accuracy, it resets daily to the split second, and adjusts automatically to Daylight Savings Time, Leap Year and Time Zone Changes. Another exciting feature of atomic watches are that they are solar powered. Atomic watches could play a major role in mobile time keeping.
