This Porthole Radio Control Clock combines the best of both worlds; the modern-day electronics of a radio control clock with the traditional beauty of a solid brass porthole and mahogany finished frame.

This clock receives a signal from the U.S. National Institute of Standards and Technology, Time and Frequency Division transmitter in Fort Collins, Colorado. The time is precisely controlled to an accuracy of ten billionths of a second per day.

This porthole clock is a beautiful and accurate timepiece for the home or office wall. The clock movement is easily accessible from the rear of the case.
