Prospex 1968 Heritage Diver's GMT Watch 34mm

How it wears

Wears true to its 34 mm case size

Seiko Prospex 1968 Heritage Diver's GMT Watch 34mm measures 40.8 mm lug-to-lug on a 34 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is shorter than 91% of the 7,413 watches in this database and shorter than 93% of the 390 Seiko watches listed.

A flat wrist width of 46 mm (1.81 in) or more keeps it in the balanced range, and from 55 mm (2.17 in) it starts to look compact. Below 40.8 mm (1.61 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 8.7 mm thick it is on the slim side, thinner than 92% of the watches with a listed thickness.
