The following Quartz Cuckoo Clocks use a battery powered mechanism. Most batteries will last approximately 1 year depending on conditions. All are fitted with a night shut-off switch and some have volume controls indicated in the detailed description.
During the call of cuckoo the door will open and the cuckoo bird comes out. The cuckoo bird actually flaps his wings as it cuckoos to the sound of running water in the background. The call itself is the actual recording of a cuckoo bird in the wilds.
All of these great models have a 30 day satisfaction guarantee and 1 year warranty, unless otherwise indicated. Anton Schneider cuckoo clocks have a 2 year warranty.
