King Seiko 56KS 5621-7000 Roman numerals

The 56KS series stood out due to its diversity and boldness, offering a range of designs not seen in earlier King Seiko models. It was also unique because it was the only King Seiko series produced by Suwa Seikosha, contrasting with the rest of the line, which Daini Seikosha had developed over the previous decade. One personal favorite is the Ref. 5621-7000, a model that truly captures the daring spirit of this series.

The dial is the centerpiece, boasting a crisp white finish adorned with printed Roman numerals. One might question the Roman numeral "IIII" for the number 4, but this was intentional. On watch dials, "IIII" is used instead of "IV" to achieve visual balance, harmonizing with the "VIII" on the opposite side.

Adding to the elegance, the dial is framed by applied black baguette markers, perfectly balanced thanks to the clean no-date layout. With its sleek brushed finish, the monocoque case allows access to the movement exclusively from the front.

We're offering a stunning, nearly untouched example, complete with its original straps, the iconic King Seiko buckle, the original instruction manual, and its box.

Condition report
This set is a treat for collectors.

The case remains factory sharp, with only barely noticeable scratches due to storage. The original white dial is immaculate, showing no signs of aging or fading on the indices or hands. The glass is flawless and free of any scratches.

The original case-back is beautiful, with the medallion in beautiful shape.

The watch comes with its original straps, signed buckle, instructions manual, and original box. We will offer a new pair of leather straps since it's not recommended to use the original ones.
