This is a Seiko railway pocket watch with a 100th-anniversary engraving of Ueno Station. It has a completed design with almost no differences except for the logo and other details from the watches used by train drivers, and it is characterized by excellent visibility. The battery has been replaced for the listing, and it is running. The size is 71mm vertically (including the hanging ring) and 50mm horizontally. It only differs slightly in the logo and other details from the pocket watches currently used by train drivers, and the large face provides excellent visibility. It can be carried around or used as a desk clock. There is almost no damage to the crystal, bezel, or back cover, and I think the exterior condition is generally good. As an option, the original instruction manual can be included for 1000 yen. If you need it, please leave a comment, and I will change the price and send it together.
