The King Seiko 5621-6000 is a vintage "Hi-Beat" luxury watch from the early 1970s, recognized by collectors for its clean, "time-only" design and sharp geometry. Unlike its siblings in the 56KS series, the 5621-6000 omits the day-date complication, resulting in a perfectly balanced and minimalist dial that is highly sought after today.

Excellent Condition.  Extremely rare dial.  Quickset works perfectly (hard to find).  Keeps perfect time.

It is strongly recommended to treat this vintage timepiece as non-water resistant.
