A framed day and date aperture rests at the three o'clock position, displaying a traditional Kanji and English wheel. The dial exhibits significant, prominent age-related spotting and dark degradation concentrated heavily along the outer periphery, particularly between the six and eleven o'clock positions, as well as near the four o'clock marker. The faceted dauphine hands mirror the indices with matching black center lines, showing surface aging consistent with the dial's overall vintage character.

History
The King Seiko line was established in the 1960s as a direct internal competitor to Grand Seiko, driving both divisions to achieve extraordinary heights in precision and design. The 56KS series, introduced in the late 1960s and produced into the 1970s, is widely regarded as one of the most refined and reliable iterations of the King Seiko family, blending high-beat precision with automated convenience.
