SOLD - King Seiko 56KS 5621-7021





While most of the King Seiko watches were produced by the Daini factory, 56KS was produced by the Suwa factory instead and it shared the Cal.56XX movements with 56GS (56GS was adjusted to be more accurate though). This 56KS here is rare due to the absence of date/day display, and it creates a symmetric and simple dial which is best for minimalists.

SOLD - King Seiko 56KS 5621-7021

  • Overall, this piece is in great vintage condition. The case has some light scratches and appears to be unpolished as it retains sharp edges with a beautiful Tanaka grammar of design profile.

    The original silver/white dial is very clean. The handset and crown are all original and in good condition. The original case back has some light scratches but the markings are still firm.

    The glass is in good condition with a couple of light scratches which are invisible by the naked eye.
