Omega Seamaster Planet Ocean 600M “ETNZ” Deep Black 45.5mm

How it wears

Wears true to its 45.5 mm case size

Omega Seamaster Planet Ocean 600M “ETNZ” Deep Black 45.5mm measures 52.4 mm lug-to-lug on a 45.5 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is longer than 96% of the 8,010 watches in this database and longer than 98% of the 487 Omega watches listed.

A flat wrist width of 59 mm (2.32 in) or more keeps it in the balanced range, and from 70 mm (2.76 in) it starts to look compact. Below 52.4 mm (2.06 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 19 mm thick it is on the thicker side, thicker than 100% of the watches with a listed thickness.
