How the King Seiko KSK wears
Its lugs add 6.6 mm to the 37 mm case, close to the 7.1 mm typical across the almanac, so its diameter is a fair guide to how it wears.
On our fit model it sits best on wrists from 6.25" to 7.25" (15.9–18.4 cm); below 6.25" the lugs start to reach the edge of the wrist.
At 12.1 mm thick it is thicker than 77% of the 56 other dress watches we've measured, so expect it to sit tall on the wrist.
Its 19 mm lug width is one of the most common strap sizes; 21 other watches here share it, so aftermarket straps are easy to find.
Will the King Seiko KSK fit your wrist?
With a 43.6 mm lug-to-lug, here is how it wears across common wrist sizes. We estimate the flat top of each wrist from its circumference; measure yours for a closer answer in the fit finder.
| Wrist | Flat width (est.) | Fit |
|---|---|---|
| 6" | 47.2 mm | Snug, lugs near the edge |
| 6.5" | 51.2 mm | Ideal fit |
| 7" | 55.1 mm | Ideal fit |
| 7.5" | 59.1 mm | Wears small |
| 8" | 63 mm | Wears small |
