This is a vintage travel alarm clock made by the German watchmaker KIENZLE. I purchased this item as dead stock and used it a few times by winding the spring, but the spring no longer winds and it has stopped working. Inside, there was a red paper-like material attached, but it easily peeled off due to aging and was discarded. Also, the lid closes, but it doesn't seem to close tightly. I was told by someone who can repair it that there is a possibility it could work if repaired, but I don't think I will have it repaired, so I will sell it to someone who understands the current condition. Design: This is a folding case integrated design manufactured from the 1960s to the 1970s. Specifications: Movement: Mostly "hand-wound," with a type that winds the mainspring by turning the knob on the back. Dial: Features a highly visible mid-century style design with white indexes on a black background. Country of Manufacture: Made in Germany (MADE IN GERMANY). Usage: Designed to be compactly stored when the case is closed, making it portable for travel. Case Size: Approximately 7 cm in height and 7 cm in width.
