Prospex Seiko Diver’s Watch 60th Anniversary Limited Edition 45.4mm

How it wears

Wears smaller than its 45.4 mm case suggests

Seiko Prospex Seiko Diver’s Watch 60th Anniversary Limited Edition 45.4mm measures 50.4 mm lug-to-lug on a 45.4 mm case, a lug-to-lug ratio of 1.11 against a database median of 1.18. That span is longer than 87% of the 7,413 watches in this database and longer than 96% of the 390 Seiko watches listed.

A flat wrist width of 56 mm (2.20 in) or more keeps it in the balanced range, and from 68 mm (2.68 in) it starts to look compact. Below 50.4 mm (1.98 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 16 mm thick it is on the thicker side, thicker than 96% of the watches with a listed thickness.
