Amphibia Classic 420059

Its lugs add 7 mm to the 39 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 6.5" to 7.75" (16.5–19.7 cm); below 6.5" the lugs start to reach the edge of the wrist.

At 15 mm thick it is thicker than 94% of the 124 other dive watches we've measured, so expect it to sit tall on the wrist.

Its 18 mm lug width is one of the most common strap sizes; 15 other watches here share it, so aftermarket straps are easy to find.
