SEIKO pocket watch, a railway watch. Size: 71mm top to bottom (including the hanging ring), 50mm wide. A rare model with "JAPAN F" engraved. Most similar watches available have "JAPAN A" engraved and a curved crystal, making this a valuable collector's item. The face is only slightly different in logo, etc., from the pocket watches currently used by railway conductors, and the large face offers excellent visibility. It can be carried around or used as a desk clock. It's a quartz watch, so there's almost no delay or advance, and the battery was replaced in July 2025, so it's ready to use. There is no significant damage to the body, crystal, or back cover. As an option, the original instruction manual can be included for 1000 yen. If you need it, please comment, and the price will be adjusted, and it will be shipped together. - Brand: SEIKO - Model: Pocket Watch - Dial Color: White - Numerals Style: Arabic numerals - Country of Manufacture: Japan
