How the Seiko 5 Sports SKX Sports Style wears

Its lugs add only 3.5 mm to the 42.5 mm case, against 7.1 mm typical across the almanac, so it wears smaller than its diameter suggests.

On our fit model it sits best on wrists from 6.5" to 7.75" (16.5–19.7 cm); below 6.5" the lugs start to reach the edge of the wrist.

At 13.4 mm thick it is thicker than 87% of the 52 other sport watches we've measured, so expect it to sit tall on the wrist.

Its 22 mm lug width is one of the most common strap sizes; 27 other watches here share it, so aftermarket straps are easy to find.

Will the Seiko 5 Sports SKX Sports Style fit your wrist?

With a 46 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.
