Omega Speedmaster Calibre 321 Chronograph 38 6 mm

How it wears

Wears larger than its 38.6 mm case suggests

Omega Speedmaster Calibre 321 Chronograph 38 6 mm measures 48 mm lug-to-lug on a 38.6 mm case, a lug-to-lug ratio of 1.24 against a database median of 1.18. That span is longer than 63% of the 8,010 watches in this database and longer than 60% of the 487 Omega watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 48 mm (1.89 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 13.92 mm thick it is on the thicker side, thicker than 82% of the watches with a listed thickness.
