Speedmaster Moonphase Co-Axial Master Chronometer Moonphase Chronograph 43 mm

How it wears

Wears smaller than its 43 mm case suggests

Omega Speedmaster Moonphase Co-Axial Master Chronometer Moonphase Chronograph 43 mm measures 48.6 mm lug-to-lug on a 43 mm case, a lug-to-lug ratio of 1.13 against a database median of 1.18. That span is longer than 72% of the 7,421 watches in this database and longer than 67% of the 487 Omega watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 65 mm (2.56 in) it starts to look compact. Below 48.6 mm (1.91 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 13.61 mm thick it is on the thicker side, thicker than 75% of the watches with a listed thickness.
