Battleship Yamato Pocket Watch - As Is

This item was found while cleaning out my grandfather's house. It is a pocket watch with the battleship Yamato on the back cover. It is a beautiful item with no major scratches or dirt.
The edges of the watch have fine detailing, and the large watch face is very easy to read.

It has a battery and has been tested for operation.
Please note that it is not a new battery.

Please check the photos for other details.
The size is approximately 7 cm in height and 4.5 cm in width.
