How the Casio A158W wears
Its lugs add only 3.6 mm to the 33.2 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 5.5" to 6" (14.0–15.2 cm).
At 8.2 mm thick it is slimmer than 89% of the 18 other digital watches we've measured, so it slides under a cuff more easily than most.
Will the Casio A158W fit your wrist?
With a 36.8 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 | Wears small |
| 7" | 55.1 mm | Wears small |
| 7.5" | 59.1 mm | Wears small |
| 8" | 63 mm | Wears small |
