Chronomat B01 42

How it wears

Wears smaller than its 42 mm case suggests

Breitling Chronomat B01 42 measures 45.8 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.09 against a database median of 1.18. That span is shorter than 66% of the 7,413 watches in this database and shorter than 78% of the 298 Breitling watches listed.

A flat wrist width of 51 mm (2.01 in) or more keeps it in the balanced range, and from 62 mm (2.44 in) it starts to look compact. Below 45.8 mm (1.80 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 13.77 mm thick it is on the thicker side, thicker than 77% of the watches with a listed thickness.
