In 2021, the Seiko Time Company celebrated their 140th anniversary by reissuing the King Seiko name to a limited production of high-end, vintage inspired timepieces. Limited to just 3000 pieces, the King Seiko SDKA001 is heavily inspired by the KS 44-9990 produced in the late 60's by the brand. The reissue features an enlarged 38mm case size, a sapphire crystal, an upgraded movement from Seiko's 6L series of Calibers, and the iconic Gold Shield Medallion on the caseback.

This watch is numbered 2589 out of 3000 and comes with the original display box, manual, and warranty slip.
