Santos-Dumont Large 31.4mm

How it wears

Wears larger than its 31.4 mm case suggests

Cartier Santos-Dumont Large 31.4mm measures 43.5 mm lug-to-lug on a 31.4 mm case, a lug-to-lug ratio of 1.39 against a database median of 1.18. That span is shorter than 82% of the 7,421 watches in this database and shorter than 32% of the 196 Cartier watches listed.

A flat wrist width of 49 mm (1.93 in) or more keeps it in the balanced range, and from 58 mm (2.28 in) it starts to look compact. Below 43.5 mm (1.71 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
