The screen has many scratches and the characters inside are not visible, but when zoomed in, they appear as shown in the 5th image. I researched on Google and the result suggests it might be a SEIKO 14K 21JEWELS. It's a very old antique item, so how about adding it to your collection if you collect such items? I have investigated as much as possible, but the above is all I know, and I don't know the exact manufacturer or model. It's just a guess, so if you are interested, I recommend you research it yourself. The winding part is missing, and the hands cannot be moved. There is no battery, so the operation has not been confirmed. If you have any other questions, please comment. I will retake photos. There is no box or instruction manual. It will be wrapped in bubble wrap and shipped via Nekopos. If you prefer Rakuraku Mercari Delivery (courier service), please comment in advance.
