These German cuckoo clocks are typical of most. Some Cuckoo Clocks are quite complex and can be very challenging to work on. Many clock repair shops will not work on these as they are particularly difficult to take apart and reassemble.
Two German Cuckoo Clocks
The simpler versions such as these two examples all have the same basic configuration of levers, push rods, and bellows. The more complex models can have rotating dancers, water wheels, and moving figures such as a man chopping wood.
1-Day and 8-Day
The two examples featured here are Eight day and One day duration clocks. One can usually tell the difference by observing the size of the weights. Typically, the Eight day versions use the larger weights.
Collectible if Not Valuable
Cuckoo clocks can always be purchased at auctions at reasonable prices as their collectible value is not high, but be prepared to do some work when you purchase one. I have never purchased a Cuckoo clock from an auction that has not required extensive repairs. The bellows nearly always need replacing and due to the poor quality movements installed in most Cuckoo clocks, bushing work may be needed as they all have thin plates.
