This is a SEIKO pocket watch, a railway watch. The size is 71mm top to bottom (including the hanging ring) and 50mm wide. It is engraved with "JAPAN F" and is a rare model with a flat back cover. Most of the same type of watches on the market are engraved with "JAPAN A" and have a curved windshield, so it is recommended as a rare item for collection. The large face offers excellent visibility, with only slight differences in the logo and other details from the pocket watches currently used by railway drivers. It can be carried around or used as a desk clock. As it is a quartz watch, there is almost no delay or advance, and it is currently running, so you can use it immediately. There is no damage due to aging on the bezel or the back cover. As an option, you can also purchase the original instruction manual for 1000 yen. If you need it, please leave a comment and we will change the price and include it with your order. - Brand: SEIKO - Model: Pocket Watch - Dial Color: White - Numerals Style: Arabic Numerals - Country of Manufacture: Japan
