How the Commander Big Date wears

Its lugs add only 3 mm to the 42 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 6.25" to 7.5" (15.9–19.1 cm); below 6.25" the lugs start to reach the edge of the wrist.

At 12 mm thick it is thicker than 78% of the 166 other everyday watches we've measured, so expect it to sit tall on the wrist.

Its 22 mm lug width is one of the most common strap sizes; 65 other watches here share it, so aftermarket straps are easy to find.

Will the Commander Big Date fit your wrist?

With a 45 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.

6.5"	51.2 mm	Ideal fit
7"	55.1 mm	Ideal fit
