Seamaster Planet Ocean 600M 43.5

Its lugs add only 5.5 mm to the 43.5 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 6.75" to 8.25" (17.1–21.0 cm); below 6.75" the lugs start to reach the edge of the wrist.

At 16.1 mm thick it is thicker than 99% of the 79 other dive watches we've measured, so expect it to sit tall on the wrist.

Its 21 mm lug width is one of the most common strap sizes; 28 other watches here share it, so aftermarket straps are easy to find.
