How the Mantis (Gen2) wears

Its lugs add 8.5 mm to the 37.5 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 11.5 mm thick it is slimmer than 58% of the 26 other field watches we've measured, so it slides under a cuff more easily than most.

Its 18 mm lug width is one of the most common strap sizes; 12 other watches here share it, so aftermarket straps are easy to find.

Will the Mantis (Gen2) fit your wrist?

With a 46 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	Snug, lugs near the edge
6.5"	51.2 mm	Ideal fit
7"	55.1 mm	Ideal fit
7.5"	59.1 mm	Ideal fit
