This is a Seiko railway pocket watch with the JR East Tohoku engraving. It is a watch that was used by train drivers when JR was first established. Unlike other Seiko railway pocket watches, the metal parts have a slightly bronze tint, and the JR logo on the dial is also a unique feature not found in other models. The battery has been replaced and it is in working condition. The size is 71mm (including the hanging ring) vertically and 50mm horizontally. The large face provides excellent visibility, with only slight differences in the logo compared to the pocket watches currently used by train drivers. It can be carried around or used as a desk clock. The crystal, bezel, and back cover have minor scratches that appear to have been made during use by a train driver.
