How the SWR103 wears
Its lugs reach 11.8 mm past the 27.2 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 5.5" to 6.5" (14.0–16.5 cm).
At 6.4 mm thick it is slimmer than 83% of the 47 other rectangular watches we've measured, so it slides under a cuff more easily than most.
Its 22 mm lug width is one of the most common strap sizes; 59 other watches here share it, so aftermarket straps are easy to find.
Will the SWR103 fit your wrist?
With a 39 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 | Ideal fit |
| 6.5" | 51.2 mm | Ideal fit |
| 7" | 55.1 mm | Wears small |
| 7.5" | 59.1 mm | Wears small |
| 8" | 63 mm | Wears small |
