My memory is vague, but I probably bought it at a shop that looked like an antique store about 25 years ago. I kept it put away and recently found it! It is not currently working. It says "Quartz" on it, so it might work with a battery change, but there's also a possibility it's broken. How about someone who can fix it themselves, or collect it as a part-source antique item? I cannot accept returns or complaints after purchase, so please purchase only if you understand and agree. *If I replace the battery and confirm it works, I will increase the price. (Battery replacement cost + a) I'm not sure about the material, but I think it's probably brass.
