Navitimer B12 Chronograph 41 Cosmonaute

How it wears

Wears true to its 41 mm case size

Breitling Navitimer B12 Chronograph 41 Cosmonaute measures 47 mm lug-to-lug on a 41 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is shorter than 47% of the 7,413 watches in this database and shorter than 73% of the 298 Breitling watches listed.

A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 47 mm (1.85 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
