Railroad Pocket Watch, SEIKO Dial Color: White Japanese National Railways, Tokyo South Railway Administration (Tōnan-tetsu) Serial number included Stamped: Showa 46 (1971) Manual winding It is running, but I don't know if it is slow. A purple string was attached, but it is dirty, so I will only include it if you want it. There are fine scratches like in image 4. I am not familiar with railroads or watches, so I cannot answer in-depth questions.
