Chronomat B01 Chronograph 42

How it wears

Wears true to its 42 mm case size

Breitling Chronomat B01 Chronograph 42 measures 48.5 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is longer than 70% of the 7,421 watches in this database and longer than 39% of the 298 Breitling watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 65 mm (2.56 in) it starts to look compact. Below 48.5 mm (1.91 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 15.1 mm thick it is on the thicker side, thicker than 93% of the watches with a listed thickness.
