This is a pocket watch from the Showa 20s (1945-1954). It's a rare enamel dial model, originally used as a post-war railway watch. The exterior nickel-plated case shows some rust. The dial is in very good condition with no cracks or discoloration. The watch is running without any problems, keeping time within ±30 seconds when laid flat. The balance staff appears to have been replaced, so maintenance shouldn't be needed for a while. Please note that price negotiations are not possible.
