The King Seiko (KS) line was created in 1961 as Seiko's high-grade mechanical series positioned just below Grand Seiko.
The 56KS series (1968–1975) was produced by Suwa Seikosha and featured:
Hi-Beat automatic movements
High accuracy for its era
The refined “Grammar of Design” case style
Strong edges and polished flat surfaces
Day-Date display (on 5626 models)
The 5626-7111 is regarded as one of the later refinements of the 56KS family, offering a clean case design, high-frequency movement, and strong historical significance from the final years of Seiko’s mechanical era before quartz dominance.
King Seiko models from this period are sought after by collectors for their precision engineering and timeless design.
