Seamaster Railmaster 38

Its lugs add 6.9 mm to the 38 mm case, close to the 7.1 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 6.25" to 7.5" (15.9–19.1 cm); below 6.25" the lugs start to reach the edge of the wrist.

At 12.4 mm thick it is thicker than 58% of the 26 other field watches we've measured, so expect it to sit tall on the wrist.

Its 19 mm lug width is one of the most common strap sizes; 21 other watches here share it, so aftermarket straps are easy to find.
