We have not verified this watch’s lug-to-lug yet, so we can’t draw it on a wrist. Case diameter alone is a poor guide to fit.

How the Seastar 2000 Professional 46mm wears

At 16.3 mm thick it is thicker than 98% 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.
