Why it matters

The simpler markers and the more assertive lug facets give the early King Seiko vocabulary a much more abstract, assured expression.

What I look at

The lugs begin to negotiate a common outline with the round case. Their outer sides approach a tangent relationship.

One basic index repeats around the dial, doubled at twelve. The composition gains clarity through repetition and carefully judged differences in size.
