Datejust Lady 31

How it wears

Wears true to its 31 mm case size

Rolex Datejust Lady 31 measures 37 mm lug-to-lug on a 31 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is shorter than 95% of the 7,413 watches in this database and shorter than 94% of the 50 Rolex watches listed.

A flat wrist width of 42 mm (1.65 in) or more keeps it in the balanced range, and from 50 mm (1.97 in) it starts to look compact. Below 37 mm (1.46 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
