This is Loetscher's classic Heidi cuckoo clock. This model features four rosy-cheeked musicians from the Appenzell region of Switzerland, clothed in traditional costumes and playing traditional instruments. Loetscher's cuckoo bird calls out on the hour, after which one of two delightful tunes plays alternately, sending our dancers waltzing across the balcony and our musicians swaying in time with the music.
