Constellation Co-Axial Master Chronometer 39 mm

How it wears

Wears smaller than its 39 mm case suggests

Omega Constellation Co-Axial Master Chronometer 39 mm measures 41 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.05 against a database median of 1.18. That span is shorter than 90% of the 7,413 watches in this database and shorter than 88% of the 487 Omega watches listed.

A flat wrist width of 46 mm (1.81 in) or more keeps it in the balanced range, and from 55 mm (2.17 in) it starts to look compact. Below 41 mm (1.61 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 12.43 mm thick it sits within the typical range, thicker than 54% of the watches with a listed thickness.
