The face of the Fort Knox cuckoo clock designed by Ewald Winkelbauer is skilfully crafted in gold, silver or copper leaf by expert hands. This very special, precious, elegant, age-old finish combines with the square-cornered, minimalist design parallelepiped frame to give a modern look that suits any environment. Can be used wall mounted or free standing. Made from wood coated with non-toxic paint. The high-quality, German-designed cuckoo movement is powered by two batteries, a light sensor prevents the cuckoo from calling when it is dark. A switch allows the sound to be regulated or switched off completely.
