Rotonde de Cartier 45mm

How it wears

Wears smaller than its 45 mm case suggests

Cartier Rotonde de Cartier 45mm measures 50.5 mm lug-to-lug on a 45 mm case, a lug-to-lug ratio of 1.12 against a database median of 1.18. That span is longer than 87% of the 7,421 watches in this database and longer than 97% of the 196 Cartier watches listed.

A flat wrist width of 57 mm (2.24 in) or more keeps it in the balanced range, and from 68 mm (2.68 in) it starts to look compact. Below 50.5 mm (1.99 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
