How the Gentleman Powermatic 80 Silicium 40mm wears

Its lugs add 8 mm to the 40 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 6.75" to 8" (17.1–20.3 cm); below 6.75" the lugs start to reach the edge of the wrist.

At 11.5 mm thick it is thicker than 55% of the 56 other dress watches we've measured, so expect it to sit tall on the wrist.

Its 21 mm lug width is one of the most common strap sizes; 28 other watches here share it, so aftermarket straps are easy to find.

Will the Gentleman Powermatic 80 Silicium 40mm fit your wrist?

With a 48 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	Snug, lugs near the edge
7"	55.1 mm	Ideal fit
