Prospex 1968 Heritage Diver's GMT Watch 44.5mm

How it wears

Wears true to its 44.5 mm case size

Seiko Prospex 1968 Heritage Diver's GMT Watch 44.5mm measures 51.6 mm lug-to-lug on a 44.5 mm case, a lug-to-lug ratio of 1.16 against a database median of 1.18. That span is longer than 93% of the 7,413 watches in this database and longer than 97% of the 390 Seiko 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 51.6 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 13.7 mm thick it is on the thicker side, thicker than 76% of the watches with a listed thickness.
