Chronomat B01 42

How it wears

Wears true to its 42 mm case size

Breitling Chronomat B01 42 measures 50.5 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is longer than 87% of the 7,413 watches in this database and longer than 54% of the 298 Breitling 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.
