This is a beautiful vintage King Seiko, reference number 5621-7000, from the highly regarded 56KS series produced by Seiko's Suwa Seikosha division. King Seiko was positioned as a high-end line, second only to Grand Seiko, and is known for its excellent build quality and accurate movements. The 5621-7000 is one of the more unique models in the 56KS line, featuring a non-date (dateless) dial, which is relatively rare among King Seiko automatics. This characteristic eliminates the concern of the day/date quick-set mechanism issue sometimes associated with the 56-series movements, making it a highly desirable model for daily wear. Movement: Caliber 5621A, an automatic (self-winding) Hi-Beat movement (28,800 bph) with manual winding and hacking (stop-seconds) function. Case: Features a distinctive, rounded square or cushion-shaped one-piece case (monocoque case), which was designed for superior water resistance at the time. The case back is adorned with the original Gold KS Medallion. Dial: The dial often features a matte finish or a subtle sunburst effect, with either applied Roman numeral or simple bar indices, depending on the specific model variation. The non-date configuration provides a clean, elegant look. Crown: Signed with the characteristic "KS" logo. A Classic Vintage: This model represents the high-quality craftsmanship of Japanese watchmaking in the late 1960s to early 1970s. [ Appearance ] Scuffs from normal use. *Please check photos.
