Speedmaster 38 Co-Axial Chronometer Chronograph 38 mm

How it wears

Wears true to its 38 mm case size

Omega Speedmaster 38 Co-Axial Chronometer Chronograph 38 mm measures 45 mm lug-to-lug on a 38 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is shorter than 70% of the 7,413 watches in this database and shorter than 66% of the 487 Omega watches listed.

A flat wrist width of 50 mm (1.97 in) or more keeps it in the balanced range, and from 60 mm (2.36 in) it starts to look compact. Below 45 mm (1.77 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 14.75 mm thick it is on the thicker side, thicker than 90% of the watches with a listed thickness.
