The term Quartz Cuckoo Clock refers to the type of movement that is used in a clock. Unlike authentic cuckoo clocks from the Black Forest region of Germany, which were powered entirely by mechanical moving parts, Quartz movement clocks are battery operated. With this modernization to electronic movements, the quartz cuckoo clocks do not qualify for VdS certification. However, there are still reputable manufacturers that produce high quality, authentic-looking quartz clocks. Some even feature detailed hand-carved elements you would expect to find on a vintage clock. Click here to learn more about the Quartz Cuckoo Clocks..
