History Introduced in the late 1960s, the King Seiko line was born from an internal rivalry between the Suwa and Daini factories, driving both to achieve unprecedented levels of accuracy and design refinement. The 56KS series, powered by the 5600 family of high-beat movements, became one of the most successful and beloved iterations. The distinctive case shapes, influenced by Taro Tanaka, established a visual language that remains iconic to this day, securing King Seiko's legacy as a true giant of vintage watchmaking. / Second Vintage SKU: SEI-KXX-0001
