How the Khaki Field Auto 42mm wears

Its lugs reach 11 mm past the 42 mm case, more than the 7.1 mm typical across the almanac, so it wears larger than its diameter suggests.

On our fit model it sits best on wrists from 7.25" to 8.5" (18.4–21.6 cm); below 7.25" the lugs start to reach the edge of the wrist.

At 11 mm thick it is slimmer than 77% of the 26 other field 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 Khaki Field Auto 42mm fit your wrist?

With a 53 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.
