History The reference 5626-7110 was introduced in 1971 as a major redesign of the standard King Seiko 5626-7000 case and dial. Early production models, like this 1971 example, featured the highly desirable gold KS medallion on the caseback, while later production runs replaced it with an engraved KS roundel. In late 1972, the 5626-7110 was replaced by the 5626-7111, which abandoned the monobloc case for a screw-back design. Today, early medallion-equipped examples of the 56KS series remain a firm collector favourite for their elegant proportions and high-beat mechanical sophistication.
