How the BR 03 Black Steel wears

Its lugs add only 0 mm to the 41 mm case, against 7 mm typical across the almanac, so it wears smaller than its diameter suggests.

On our fit model it sits best on wrists from 5.75" to 6.75" (14.6–17.1 cm); below 5.75" the lugs start to reach the edge of the wrist.

At 9.7 mm thick it is thicker than 81% of the 47 other rectangular watches we've measured, so expect it to sit tall on the wrist.

Its 24 mm lug width is less common (4 other watches here), so check strap sizes carefully.

Will the BR 03 Black Steel fit your wrist?

With a 41 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.
