The King Seiko 5626-7040 is a high-precision, automatic "Hi-Beat" watch from the early 1970s. It is particularly noted for being an Officially Certified Chronometer, a status Seiko sought for a brief period to compete directly with Swiss watchmaking dominance.

Excellent Condition.  Beautifully aged Dial with a nice Patina.  Quickset works perfectly (hard to find).  Keeps perfect time.

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