Radio Controlled Clock Movement
Accurate to within 1 second per million years!
The most accurate clock in the world today is an atomic clock. In the United States, radio and television stations, power companies and air traffic control systems and other users requiring the most accurate time keeping all use the same source - the Cesium Atomic Clock in Ft. Collins, Colorado.
The National institute of Standards and Technology (NIST) broadcasts a radio signal from a site near Ft. Collins on radio station WWVB. The accuracy of this time signal is within 1 second per million years! The radio signal is the key to the accuracy of the radio controlled clocks.
Our radio controlled clock takes this accuracy one step further by allowing the user to input their local time zone and automatically adjust to daylight savings time. The signal the radio controlled clock receives is updated daily, insuring that you have the most accurate, commercially available clock today.
Practical Considerations: Because of the nature of radio signals, reception of the signal will vary. Performance of this movement will be affected inside metal buildings and the use of metal clock dials or cases should be avoided. A second hand should be ordered with the radio controlled movements. It will make it easier to initially set the movement and see the accuracy of the movement as well. Click here to view our selection of second hands.

Optional second hands are available in our Sweep Second Hand section.
