Astron Nexter GPS Solar 2025 43.4mm

How it wears

Wears smaller than its 43.4 mm case suggests

Seiko Astron Nexter GPS Solar 2025 43.4mm measures 49.5 mm lug-to-lug on a 43.4 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is longer than 79% of the 7,421 watches in this database and longer than 87% of the 390 Seiko watches listed.

A flat wrist width of 55 mm (2.17 in) or more keeps it in the balanced range, and from 66 mm (2.60 in) it starts to look compact. Below 49.5 mm (1.95 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
