An excellent and high grade WWII Japanese Navy timepiece. Thanks for posting it.

As you know, Seikosha was the original name of the Seiko co. There products were limited to clocks of the American type. Then, in the late 1920's or early 1930's a line of pocket and wrist watches were added.

Best regards,
