This is a Seiko railway pocket watch. The back cover is engraved with the 20th anniversary of the Tokaido Shinkansen's opening. Being quartz, there is almost no time deviation. The exterior has dirt and damage on the crystal, bezel, and back cover. Please check the condition in the photos. The size is 71mm vertically (including the hanging ring) and 50mm horizontally. The large face offers excellent visibility, with only slight differences in the logo and other details compared to the pocket watches currently used by railway conductors. It can be carried around or used as a desk clock. As an option, the original instruction manual from the time can be included for 1000 yen. If you need it, please leave a comment, and the price will be adjusted, and it will be shipped together.
