How the Pilot's Watch Mark XX wears

Its lugs reach 9.2 mm past the 40 mm case, more than the 7.1 mm typical across the almanac, so it wears larger than its diameter suggests.

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 10.8 mm thick it is slimmer than 100% of the 14 other pilot watches we've measured, so it slides under a cuff more easily than most.

Its 20 mm lug width is one of the most common strap sizes; 104 other watches here share it, so aftermarket straps are easy to find.

Will the Pilot's Watch Mark XX fit your wrist?

With a 49.2 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.
