How the Trekker 39 Matte Black (no-date) wears
Its lugs reach 9 mm past the 39 mm case, more than the 7 mm typical across the almanac, so it wears larger than its diameter suggests.
On our fit model it sits best on wrists from 6.75" to 8" (17.1–20.3 cm); below 6.75" the lugs start to reach the edge of the wrist.
At 12.5 mm thick it is slimmer than 65% of the 124 other dive watches we've measured, so it slides under a cuff more easily than most.
Its 20 mm lug width is one of the most common strap sizes; 156 other watches here share it, so aftermarket straps are easy to find.
Will the Trekker 39 Matte Black (no-date) fit your wrist?
With a 48 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 |
