Thank you for your interest. This is a wristwatch my wife bought for me when I needed it for commuting to high school by train. How about it as a retro collection? ☆ Manufacturer: SEIKO ☆ Brand: Unknown ☆ Structure: Automatic mechanical, 17 jewels, SUS ☆ Year of purchase: 1978 ☆ Remarks: It is working. There are scratches on the glass surface.
