I found this while cleaning up after a move. It's quite old. If you're interested in purchasing, please comment first. After that, I will take it to a watch shop to have a battery installed and confirm that it works. If it works, you can then purchase it. Please be sure to purchase it if the operation is confirmed to be problem-free. Please only comment if you understand this. Of course, questions are also welcome. The price is the price if the operation is confirmed to be problem-free. If there are any problems with the operation check, I will cancel the listing myself.
