Royal Oak Selfwinding 39mm

How it wears

Wears larger than its 39 mm case suggests

Audemars Piguet Royal Oak Selfwinding 39mm measures 49.3 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.26 against a database median of 1.18. That span is longer than 77% of the 7,421 watches in this database and longer than 26% of the 68 Audemars Piguet watches listed.

A flat wrist width of 55 mm (2.17 in) or more keeps it in the balanced range, and from 66 mm (2.60 in) it starts to look compact. Below 49.3 mm (1.94 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 9.3 mm thick it is on the slim side, thinner than 90% of the watches with a listed thickness.
