How the Superocean Automatic 42 wears

Its lugs add 5.7 mm to the 42 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 6.75" to 8" (17.1–20.3 cm); below 6.75" the lugs start to reach the edge of the wrist.

At 12.6 mm thick it is slimmer than 63% of the 79 other dive watches we've measured, so it slides under a cuff more easily than most.

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.

Will the Superocean Automatic 42 fit your wrist?

With a 47.7 mm lug-to-lug, here is how it wears across common wrist sizes. We estimate the flat top of each wrist from its circumference; measure yours for a closer answer in the fit finder.
