How the Pro Trek PRW-3500 wears
Its lugs add only 3.5 mm to the 53.4 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 7.75" to 8.5" (19.7–21.6 cm); below 7.75" the lugs start to reach the edge of the wrist.
At 14.5 mm thick it is thicker than 89% of the 18 other digital watches we've measured, so expect it to sit tall on the wrist.
Will the Pro Trek PRW-3500 fit your wrist?
With a 56.9 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 | Lugs overhang |
| 7" | 55.1 mm | Lugs overhang |
| 7.5" | 59.1 mm | Snug, lugs near the edge |
| 8" | 63 mm | Ideal fit |
