Buyer's Comment

This watch is equipped with a 56 series movement manufactured by Suwa Seikosha, which began production in 1968. The King Seiko 56 series offers a wide variety of cases and dials. This particular model is the King Seiko automatic Ref. 5621-7021. Its appeal lies in its simplicity, with a silver dial and dauphine hands. There are scratches on the crystal. The case has minor scratches but no significant damage from use. The hands can be adjusted smoothly. An aftermarket leather strap has been fitted.
