Seiko Prospex 1968 Heritage Diver's GMT Watch 43.5mm

How it wears

Wears true to its 43.5 mm case size

Seiko Prospex 1968 Heritage Diver's GMT Watch 43.5mm measures 49.8 mm lug-to-lug on a 43.5 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is longer than 82% of the 8,054 watches in this database and longer than 91% of the 393 Seiko watches listed.

A flat wrist width of 56 mm (2.20 in) or more keeps it in the balanced range, and from 67 mm (2.64 in) it starts to look compact. Below 49.8 mm (1.96 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 11.5 mm thick it sits within the typical range, thicker than 35% of the watches with a listed thickness.
