Seiko used the Type II designation on certain vintage quartz watches to indicate watches moderately priced in comparison to its expensive caliber series 38 and 48 watches. But at 18,000 to 34,000 yen these watches were still more expensive than most of the contemporary Seiko automatics.
These watches appear in the Seiko catalogs from 1976 through 1984. The zenith of the Type II watches was 1979 when 95 models appeared in the catalog. Offerings then quickly declined with only a few models in calibers 7123 and 8223 from 1981 through 1984.
Most of the Type II watches are high accuracy quartzes and this one too runs at 15 seconds per month.
The following calibers are included in the Type II family: 0903, 0923, 4316, 4336, 4622, 4623, 7546, 7559, 7122, 7123 and 8223.
