How the Orient Star Sports Diver wears

Its lugs add 7.5 mm to the 43.6 mm case, close to the 7 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 7" to 8.5" (17.8–21.6 cm); below 7" the lugs start to reach the edge of the wrist.

At 14 mm thick it is thicker than 80% of the 124 other dive 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; 42 other watches here share it, so aftermarket straps are easy to find.

Will the Orient Star Sports Diver fit your wrist?

With a 51.1 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.
