How it wears

Wears smaller than its 38 mm case suggests

Girard-Perregaux x Bamford Deep Diver 38mm measures 40.3 mm lug-to-lug on a 38 mm case, a lug-to-lug ratio of 1.06 against a database median of 1.18. That span is shorter than 92% of the 8,010 watches in this database.

A flat wrist width of 45 mm (1.77 in) or more keeps it in the balanced range, and from 54 mm (2.13 in) it starts to look compact. Below 40.3 mm (1.59 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 13.91 mm thick it is on the thicker side, thicker than 82% of the watches with a listed thickness.
