Speedmaster Pilot Co-Axial Master Chronometer Chronograph 40 85 mm

How it wears

Wears larger than its 40.85 mm case suggests

Omega Speedmaster Pilot Co-Axial Master Chronometer Chronograph 40 85 mm measures 49.6 mm lug-to-lug on a 40.85 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is longer than 80% of the 7,421 watches in this database and longer than 74% of the 487 Omega 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 49.6 mm (1.95 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 14.65 mm thick it is on the thicker side, thicker than 89% of the watches with a listed thickness.
