How the G-Shock Mudmaster GWG-B1000 wears
Its lugs add 6.6 mm to the 52.1 mm case, close to the 7 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 8" to 8.5" (20.3–21.6 cm); below 8" the lugs start to reach the edge of the wrist.
At 16.2 mm thick it is thicker than 94% of the 18 other digital watches we've measured, so expect it to sit tall on the wrist.
Will the G-Shock Mudmaster GWG-B1000 fit your wrist?
With a 58.7 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 | Lugs overhang |
| 7" | 55.1 mm | Lugs overhang |
| 7.5" | 59.1 mm | Lugs overhang |
| 8" | 63 mm | Ideal fit |
