How the PRX Automatic Chronograph 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 14.5 mm thick it is thicker than 79% of the 24 other chronograph watches we've measured, so expect it to sit tall on the wrist.
Will the PRX Automatic Chronograph 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.
| Wrist | Flat width (est.) | Fit |
|---|---|---|
| 6" | 47.2 mm | Lugs overhang |
| 6.5" | 51.2 mm | Lugs overhang |
| 7" | 55.1 mm | Snug, lugs near the edge |
| 7.5" | 59.1 mm | Ideal fit |
| 8" | 63 mm | Ideal fit |
