How the Elegance GMT wears

Its lugs add 7.4 mm to the 39.5 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 6.5" to 7.75" (16.5–19.7 cm); below 6.5" the lugs start to reach the edge of the wrist.

At 13.7 mm thick it is thicker than 98% of the 56 other dress watches we've measured, so expect it to sit tall on the wrist.

Its 19 mm lug width is one of the most common strap sizes; 21 other watches here share it, so aftermarket straps are easy to find.

Will the Elegance GMT fit your wrist?

With a 46.9 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.

Wrist	Flat width (est.)	Fit
6"	47.2 mm	Lugs overhang
6.5"	51.2 mm	Ideal fit
7"	55.1 mm	Ideal fit
7.5"	59.1 mm	Ideal fit
