This attractive brushed-metal finish clock reveals a cheerful surprise every hour on the hour, when the doors open and the brightly-colored timekeeper steps up to his microphone to announce the current time or to play a happy melody! * Reports hourly between 6 am and 9 pm. * The Radio-Controlled Cuckoo Clock monitors itself automatically by receiving radio signals from the official U.S. Atomic clock in Fort Collins, Colorado, where scientists measure time in fractions of a second. * Uses two "C" and two "AA" batteries, not included. * Measures 11"H x 8"W x 2"D.
