Orient Star Small Second See-Through Back This is an antique watch with a small second hand and a see-through back. It was purchased from an antique watch store in Tokyo. I have used it occasionally, but it has not been overhauled. The daily rate is about 1 minute when laid flat. (This does not guarantee accuracy.) The strap is dirty and worn.
