This is a Seiko railway pocket watch with a 100th-anniversary engraving of Ueno Station. It has a refined design with excellent visibility, differing only slightly from the watches used by train drivers in terms of the logo and other details. The watch has been fitted with a new battery and is in working order. The size is 71mm vertically (including the hanging ring) and 50mm horizontally. The large face offers excellent visibility, with only minor differences in the logo compared to the pocket watches currently used by train drivers. It can be carried around or used as a desk clock. The crystal, bezel, and back cover have minimal damage, and the overall exterior condition is good. As an option, the original instruction manual from the time can be included for 1000 yen. If you would like it, please leave a comment, and I will adjust the price and include it with your order.
