How the Spirit Zulu Time 42mm wears
Its lugs add 7.2 mm to the 42 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 7" to 8.25" (17.8–21.0 cm); below 7" the lugs start to reach the edge of the wrist.
At 13.9 mm thick it is thicker than 84% of the 31 other gmt watches we've measured, so expect it to sit tall on the wrist.
Its 22 mm lug width is one of the most common strap sizes; 42 other watches here share it, so aftermarket straps are easy to find.
Will the Spirit Zulu Time 42mm fit your wrist?
With a 49.2 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 | Snug, lugs near the edge |
| 7" | 55.1 mm | Ideal fit |
| 7.5" | 59.1 mm | Ideal fit |
| 8" | 63 mm | Ideal fit |
