How the BR 05 36mm Black Steel wears

Its lugs add 6.8 mm to the 36 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 6" to 7" (15.2–17.8 cm); below 6" the lugs start to reach the edge of the wrist.

At 8.5 mm thick it is thicker than 66% of the 47 other rectangular watches we've measured, so expect it to sit tall on the wrist.

Will the BR 05 36mm Black Steel fit your wrist?

With a 42.8 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.
