This is a Seiko railroad pocket watch. It was sold during the Japanese National Railways (JNR) era and features a special engraving of the JNR symbol mark, the driving wheel, on the back cover. It is currently running and, being quartz, is characterized by its high accuracy. The exterior has some damage to the bezel, but the overall condition of the exterior is generally good. 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 compared to the pocket watches currently used by train drivers. It can be carried around or used as a desk clock. As an option, the original instruction manual from that 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 sent together.
