How it wears

Wears true to its 44 mm case size

Ulysse Nardin Diver X Skeleton 44mm measures 50.3 mm lug-to-lug on a 44 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is longer than 87% of the 7,421 watches in this database and longer than 79% of the 19 Ulysse Nardin watches listed.

A flat wrist width of 56 mm (2.20 in) or more keeps it in the balanced range, and from 68 mm (2.68 in) it starts to look compact. Below 50.3 mm (1.98 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
