Dial and Hands
The well-preserved dial features a clean silver sunburst finish that plays beautifully with the light. Crisp black printing complements the bright, well-preserved applied indices, with no visible moisture damage or significant spotting to detract from its elegant appearance. Time is indicated by dauphine hands in original condition featuring black center stripes. Under macro magnification, minor surface dust and light oxidation are visible on the hands, though their shape and finish remain sharply defined.

Case and Crystal
The stainless steel case retains its sharp 'Grammar of Design' geometry, displaying honest wear through light surface scratches and scuffs consistent with age. The brushed and polished transitions remain distinct, framing the smooth integrated bezel which shows similar light surface wear. Turning the watch over reveals a highly desirable detail: the gold KS medallion on the caseback is intact and well-preserved. The watch is fitted with a period correct crown featuring crisp knurling and the signed KS logo. A clear domed acrylic crystal protects the dial, free of major scratches or crazing, providing an undistorted view of the face.

Condition

The gold caseback medallion is remarkably well-preserved.

Remarks
This King Seiko stands out for its well-preserved silver sunburst dial and the survival of its gold caseback medallion. The sharp case geometry makes it a compelling choice for enthusiasts of Japanese horology.
