Prospex Sea Solar GMT 45mm

How it wears

Wears true to its 45 mm case size

Seiko Prospex Sea Solar GMT 45mm measures 51.8 mm lug-to-lug on a 45 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is longer than 94% of the 7,421 watches in this database and longer than 98% 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 70 mm (2.76 in) it starts to look compact. Below 51.8 mm (2.04 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 13.2 mm thick it sits within the typical range, thicker than 67% of the watches with a listed thickness.
