Hamilton began producing a watch with a center or sweep second hand. The was similar to a civilian watch released in 1940 known as the Secometer or the sentinel. That model carries the designation of a 987S.  The Hamilton models with a sweep second hand (another military watch) were produced from 1940 to 1948. The 987A and 987S were fitted with Elinvar Extra hairsprings when they became available.

Hamilton also provided watches for Russia (which they do not acknowledge):
