I purchased this quite a while ago. It's a Seiko antique watch. I believe it's a watch from around 50 years ago. I don't know much about watches, so I bought it based on its appearance. I haven't used it for about 20 years, storing it at home since I last wore it. When I tested it for two days before listing it, the error was 2-3 minutes. It's unknown when it might malfunction. If any problems arise, please have it overhauled. This is a used item that has been stored at home for a long time by a non-professional. Thank you for your understanding and consideration. Thank you for looking.
