Many of the new models orbit around a select group of originals. And if you've found yourself drawn to the modern KS1969 Series, it's worth remembering the watch that inspired it all: the King Seiko 45KS Ref. 4502-8010 Chronometer Date.\u003c\/p\u003e\n\n\u003cp\u003eThe 45KS represented the evolution of the King Seiko chronometer lineage, following the earlier 4420-9990. By this time, King Seiko chronometers were independently certified by the Japan Chronometer Inspection Institute (JCII), established in December 1968, to performance levels comparable to Swiss chronometer standards of the era.\u003c\/p\u003e\n\n\u003cp\u003eAt the time, chronometer grade meant a mean daily rate across five positions within -1.0 to +10.0 seconds per day, which is equivalent to Seiko's highest internal \"A\" grade accuracy. This independent validation allowed Seiko to proudly print \"Officially Certified\" on the dial. But the 4502-8010 is more than just its movement.\u003c\/p\u003e\n\n\u003cp\u003eDesign-wise, it stands apart. The 8010's lugs are short and muscular, with sharply angled case flanks that taper downward into a convex, pebble-like silhouette. The hands are unique to the chronometer variant, retaining the signature central black stripe of the 45KS line, yet rendered straighter and less sword-like than standard models. Variations also existed within the reference, including examples like this one, fitted with a black minute hand instead of the standard configuration.\u003c\/p\u003e\n\n\u003cp\u003eIf the KS1969 series has caught your attention and you're curious about its origins, this unworn example is the definitive way to experience the source.\u003c\/p\u003e\n\n\u003cp\u003eShips from Tokyo, Japan.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCondition report\u003c\/strong\u003e\u003cbr\u003eOverall, this King Seiko is in immaculate condition.
