How it wears

Wears larger than its 34.9 mm case suggests

Cartier Roadster Midsize 34.9mm measures 42.5 mm lug-to-lug on a 34.9 mm case, a lug-to-lug ratio of 1.22 against a database median of 1.18. That span is shorter than 85% of the 7,421 watches in this database and shorter than 38% of the 196 Cartier watches listed.

A flat wrist width of 48 mm (1.89 in) or more keeps it in the balanced range, and from 57 mm (2.24 in) it starts to look compact. Below 42.5 mm (1.67 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 9.7 mm thick it is on the slim side, thinner than 87% of the watches with a listed thickness.
