How the G-Shock GA-110 wears

Its lugs add only 3.8 mm to the 51.2 mm case, against 7 mm typical across the almanac, so it wears smaller than its diameter suggests.

On our fit model it sits best on wrists from 7.5" to 8.5" (19.1–21.6 cm); below 7.5" the lugs start to reach the edge of the wrist.

At 16.9 mm thick it is thicker than 88% of the 26 other digital watches we've measured, so expect it to sit tall on the wrist.

Will the G-Shock GA-110 fit your wrist?

With a 55 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.
