The 21-jewel hand-wound movement with second setting function (allowing the seconds hand to be stopped for precise synchronization) reflects the exacting standards required by railway operations where punctuality is measured in seconds. The white dial with bold Arabic numerals delivers maximum legibility, a critical requirement for professional railway timekeeping. A meaningful collector's piece that connects Japanese horological heritage with the country's legendary rail culture. - Case diameter: 50 mm (pocket watch) Condition: Seller Grade: A - Good condition considering its vintage age.
