Introduction A Japanese open-face quartz pocket watch featuring a white dial decorated with a silhouette illustration of the historic 'Yoshitsune' (義経号) steam locomotive — one of Japan's earliest railway engines — with the name 義経号 printed in red-gold characters below centre. The dial carries Arabic numerals and elegant sword-style hands, with no subsidiary seconds register. The movement is a battery-powered Seiko quartz caliber, housed in a chrome-plated open-face case. Historical / Era context The 義経号 (Yoshitsune-go) was one of the earliest American-built locomotives imported to Japan in 1880 for the Hokkaido Colonial Railway, and it became an iconic symbol of Japanese railway history. This pocket watch is a commemorative or souvenir piece produced by Seiko, celebrating that heritage through the locomotive motif on the dial. The case reference 7C11-0010 stamped on the exterior caseback identifies the Seiko caliber 7C11 quartz movement used. Seiko has a long tradition of producing open-face pocket watches, and this piece sits within that lineage as a collector's commemorative item. Condition The watch is running and keeping good time. The watch was checked running at the time of listing with a fresh battery. Battery life and long-term accuracy are not guaranteed. As a vintage timepiece it may benefit from a service.
