On your wrist

The verdict compares the case length (L) with the flat top of your wrist. Balanced from ~15.5 cm, past the edges below ~13.5 cm.

= 6.7 in

Balanced on a 17 cm wrist: the 43.1 mm case length (L) covers 79% of an estimated 54.8 mm flat top.

Casio publishes no lug-to-lug for this model, so the verdict uses its case length (L). The strap or bracelet joins inside that length, which makes this a cautious estimate.

Casio cuts the band for wrists of 14.5–21.5 cm: your wrist is inside that range.

Flat top = circumference ÷ 3.1, a community convention, not a measurement of your arm. Compact ≤ 0.75 of the flat top, balanced ≤ 0.89, at the edge ≤ 1. Compare more watches in the watch size calculator.
