Navitimer B01 Chronograph 43 Aston Martin Aramco Formula One Team

How it wears

Wears smaller than its 43 mm case suggests

Breitling Navitimer B01 Chronograph 43 Aston Martin Aramco Formula One Team measures 49.07 mm lug-to-lug on a 43 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is longer than 76% of the 7,421 watches in this database and longer than 42% of the 298 Breitling watches listed.

A flat wrist width of 55 mm (2.17 in) or more keeps it in the balanced range, and from 66 mm (2.60 in) it starts to look compact. Below 49.07 mm (1.93 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 13.69 mm thick it is on the thicker side, thicker than 76% of the watches with a listed thickness.
