Eaglemoss Military Watches Collection.

The Seikosha company opened for business in 1881 and by 1938 it was producing a million watches a year. The company supplied the army in both an official capacity and also as the watch of choice for the japanese man on the street and by association the japanese soldier.
The Seiko Nation watch was small, but this reflected Japans lack of natural resources within its borders, this relative lack of material resource was one of the factors in Japans interest in the northern provinces of China. That interest eventually led to the second Sino-Japanese war which lasted from 1937 until the end of WWII in 1945
