How the Heritage Black Bay 41 wears

Its lugs reach 9.1 mm past the 41 mm case, more than the 7 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 11 mm thick it is slimmer than 56% of the 142 other everyday 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; 56 other watches here share it, so aftermarket straps are easy to find.

Will the Heritage Black Bay 41 fit your wrist?

With a 50.1 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.
