This is one of the old items that came out when I was organizing my parents' storehouse. I am offering it because I have no plans to use it. CITIZEN Folding Desk Clock, Wind-up, Travel Clock I believe this is the type of clock used when traveling. Please refer to the images for the exterior. I cleaned it for this listing. Since it was already clean, I only wiped off the dust from the exterior. It appears to be a wind-up type, but I have not disassembled it for cleaning or detailed inspection. The winding mechanism felt a bit stiff, so I left it as is without forcing it. The time setting and the bell switch moved. If any maintenance is required, please handle it yourself after purchase. The protective film was still on the inside of the case, so I left it as is. There are no cracks or breaks. As this is an old device, I cannot offer any guarantees. Please only purchase if you understand this. Thank you very much.
