How the AA08 Diver wears

Its lugs add only 5 mm to the 41.8 mm case, against 7.1 mm typical across the almanac, so it wears smaller than its diameter suggests.

On our fit model it sits best on wrists from 6.5" to 7.75" (16.5–19.7 cm); below 6.5" the lugs start to reach the edge of the wrist.

At 12.8 mm thick it is slimmer than 54% of the 79 other dive 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; 27 other watches here share it, so aftermarket straps are easy to find.

Will the AA08 Diver fit your wrist?

With a 46.8 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.

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