This is a Seiko railroad pocket watch with the "Presented by Japan National Railways" engraving. It's a rare model with an engraving that was never available for sale to the general public. The design is nearly identical to the watches currently used by train drivers, with the exception of the logo. It's a well-designed watch with excellent visibility. The size is 71mm (including the hanging ring) vertically and 50mm horizontally. The large face provides excellent visibility, just like the pocket watches currently used by train drivers, with only slight differences in the logo. It can be carried around or used as a desk clock. The battery has been replaced for this listing, and the watch is running. There is almost no time deviation after the battery replacement. The exterior has some scratches on the crystal, bezel, and back cover. Please check the images for the condition.
