How do Atomic clocks and watches work?
All watches receive a radio signal from the Caesium atomic, the world’s most precise clock, accurate to 1 second in 1 million years. The signal is encoded so that it can be transmitted in long wave radio form. The signal originates from the WWVB transmitter in Fort Collins, Colorado and is transmitted on a frequency of 60 kHz. The atomic watches contain an antenna and internal program to receive and encode the radio signal. It is then decoded to display the precise time. They maintain total accuracy by automatic nightly updates with the radio signal. Junghans watches and clocks may be manually updated by the user.
