How the Aquis Date 43.5 wears

Its lugs add 7.5 mm to the 43.5 mm case, close to the 7.1 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 7" to 8.5" (17.8–21.6 cm); below 7" the lugs start to reach the edge of the wrist.

At 13.1 mm thick it is thicker than 61% of the 79 other dive watches we've measured, so expect it to sit tall on the wrist.

Its 23 mm lug width is unusual, so check strap sizes carefully.

Will the Aquis Date 43.5 fit your wrist?

With a 51 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.
