Seamaster Diver 300M Co-Axial Master Chronometer 43 5 mm

How it wears

Wears true to its 43.5 mm case size

Omega Seamaster Diver 300M Co-Axial Master Chronometer 43 5 mm measures 51.5 mm lug-to-lug on a 43.5 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is longer than 92% of the 7,413 watches in this database and longer than 93% of the 487 Omega watches listed.

A flat wrist width of 58 mm (2.28 in) or more keeps it in the balanced range, and from 69 mm (2.72 in) it starts to look compact. Below 51.5 mm (2.03 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 14.47 mm thick it is on the thicker side, thicker than 87% of the watches with a listed thickness.
