How it wears

Wears true to its 43.9 mm case size

Breguet Marine Tourbillon Équation Marchante 43.9mm measures 51.5 mm lug-to-lug on a 43.9 mm case, a lug-to-lug ratio of 1.17 against a database median of 1.18. That span is longer than 93% of the 8,010 watches in this database and longer than 91% of the 23 Breguet watches listed.

A flat wrist width of 58 mm (2.28 in) or more keeps it in the balanced range, and from 69 mm (2.72 in) it starts to look compact. Below 51.5 mm (2.03 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 11.8 mm thick it sits within the typical range, thicker than 42% of the watches with a listed thickness.
