On your wrist

The verdict compares the case length (L) with the flat top of your wrist. Balanced from ~18.5 cm, past the edges below ~16.5 cm.

= 6.7 in

At the edge on a 17 cm wrist: the 52 mm case length (L) covers 95% 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.

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.
