Seamaster Diver 300M Co-Axial Master Chronometer 42 mm

How it wears

Wears true to its 42 mm case size

Omega Seamaster Diver 300M Co-Axial Master Chronometer 42 mm measures 49.9 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is longer than 82% of the 7,413 watches in this database and longer than 79% 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 49.9 mm (1.96 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 13.72 mm thick it is on the thicker side, thicker than 76% of the watches with a listed thickness.
