How it wears
Wears true to its 39.4 mm case size
Omega Constellation Observatory 39.4mm measures 47.2 mm lug-to-lug on a 39.4 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is longer than 54% of the 8,093 watches in this database and longer than 42% of the 495 Omega watches listed.
A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 47.2 mm (1.86 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 12.23 mm thick it sits within the typical range, thicker than 51% of the watches with a listed thickness.
