How the Pelagos 42 Blue wears

Its lugs add 7.7 mm to the 42 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 7" to 8.25" (17.8–21.0 cm); below 7" the lugs start to reach the edge of the wrist.

At 14.3 mm thick it is thicker than 85% of the 142 other dive watches we've measured, so expect it to sit tall on the wrist.

Will the Pelagos 42 Blue fit your wrist?

With a 49.7 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.

6.5"	51.2 mm	Snug, lugs near the edge
