Casio Edifice EFK100 Automatic 39mm

How it wears

Wears smaller than its 39 mm case suggests

Casio Edifice EFK100 Automatic 39mm measures 43.5 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.12 against a database median of 1.18. That span is shorter than 82% of the 8,010 watches in this database and shorter than 80% of the 95 Casio watches listed.

A flat wrist width of 49 mm (1.93 in) or more keeps it in the balanced range, and from 58 mm (2.28 in) it starts to look compact. Below 43.5 mm (1.71 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.

At 12.5 mm thick it sits within the typical range, thicker than 56% of the watches with a listed thickness.
