How it wears

Wears smaller than its 28.5 mm case suggests

Audemars Piguet Royal Oak Square 28.5mm measures 30 mm lug-to-lug on a 28.5 mm case, a lug-to-lug ratio of 1.05 against a database median of 1.18. That span is shorter than 98% of the 7,421 watches in this database and shorter than 97% of the 68 Audemars Piguet watches listed.

A flat wrist width of 34 mm (1.34 in) or more keeps it in the balanced range, and from 40 mm (1.57 in) it starts to look compact. Below 30 mm (1.18 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
