This cuckoo clock is battery powered and a great purchase for the person on the go. The details and deer figurine are hand caved from solid wood. When the clock strikes the hour the cuckoo birds’ door opens and the cuckoo appears and calls the hour to the sound of a waterfall and other birds singing in the forest. After the call of cuckoo one of two melodies will play to celebrate the hour. This clock is made in Germany for Sternreiter. There are both a manual and automatic shut off switch for quiet time and night use. Weights and pendulum are not shown in the photo. The pendulum will swing and the weights are purely ornamental.
