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 Superocean Heritage B20 Automatic 42 wears
At 14.3 mm thick it is thicker than 87% of the 79 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; 27 other watches here share it, so aftermarket straps are easy to find.
