History Introduced in 1968 for the Japanese market, the reference 5626-7000 is a celebrated member of the 56KS family. Its distinctive one-piece monobloc front-loading case was closely based on the architecture of the manual-winding 45 King Seiko. The 56KS series remains highly regarded among collectors for its refined design and capable mechanics, with examples retaining a well-preserved gold medallion becoming increasingly desirable.
