Premier B01 Chronograph 42

How it wears

Wears true to its 42 mm case size

Breitling Premier B01 Chronograph 42 measures 50.03 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is longer than 86% of the 7,413 watches in this database and longer than 48% of the 298 Breitling watches listed.

A flat wrist width of 56 mm (2.20 in) or more keeps it in the balanced range, and from 67 mm (2.64 in) it starts to look compact. Below 50.03 mm (1.97 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
