Official description

Though it was not the first King Seiko watch, the 1965 King Seiko KSK was, with its sharp, angular case and high functionality, the one that ultimately defined King Seiko’s character. With its resistance to water and use of a hacking seconds hand, the King Seiko KSK was more than bold and beautiful. It was an eminently practical watch that earned legions of fans. Since 2022, Seiko has revived this classic style in the King Seiko collection while endowing the result- ing watches with the modern enhancements of contemporary watchmaking. Today, Seiko introduces two new timepieces inspired by the classic KSK, each powered by the slimline Caliber 6L35. This marks the movement's first appearance in the main King Seiko collection.
