How the Yacht-Master 42 wears

Its lugs add 8 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 7" to 8.25" (17.8–21.0 cm); below 7" the lugs start to reach the edge of the wrist.

At 11.8 mm thick it is slimmer than 56% of the 52 other sport watches we've measured, so it slides under a cuff more easily than most.

Its 21 mm lug width is one of the most common strap sizes; 28 other watches here share it, so aftermarket straps are easy to find.

Will the Yacht-Master 42 fit your wrist?

With a 50 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.
