Ballon Bleu 42mm 42.1mm

How it wears

Wears smaller than its 42.1 mm case suggests

Cartier Ballon Bleu 42mm 42.1mm measures 44 mm lug-to-lug on a 42.1 mm case, a lug-to-lug ratio of 1.05 against a database median of 1.18. That span is shorter than 78% of the 7,413 watches in this database and shorter than 28% 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 59 mm (2.32 in) it starts to look compact. Below 44 mm (1.73 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
