These miniature battery powered clocks are sure to spark a smile. There is a beautiful recording of a cuckoo bird (no cuckoo bird appears). This quartz model is powered by two ?C? batteries. The chalet and figurines, hand-carved from locally sourced wood, are made with the same loving care and devotion to detail as our mechanical clocks. There are only two differences between the quartz and mechanical clocks. With the quartz there is no need for winding, and secondly, the quartz clock?s cuckoo sound is a high-quality recording. Ornaments : Ornaments are hand-carved and hand-painted, which makes each one of them original and unique. BRAND NEW IN THE BOX Switzerland Lotscher lotscher
