23 cm Two beautifully hand carved squirrels and a bird ready to take flight are featured on this traditional carved Cuckoo Clock. The carvings once again display the masterful craftsmanship here. The solid-wood cuckoo calls every half hour once and the number of the hour every full hour. The 1 day running time movement need to be wind up every day, that means you pull on the chains until the weights are up. This model has a manual night shut off. Clock face, numbers and clock hands are made of wood.
