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 44.96 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 73% of the 7,413 watches in this database and shorter than 68% 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 44.96 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 14.73 mm thick it is on the thicker side, thicker than 90% of the watches with a listed thickness.
