Astron GPS Solar 2026 Limited Edition 41.2mm

How it wears

Wears true to its 41.2 mm case size

Seiko Astron GPS Solar 2026 Limited Edition 41.2mm measures 48.6 mm lug-to-lug on a 41.2 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is longer than 72% of the 7,421 watches in this database and longer than 80% of the 390 Seiko watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 65 mm (2.56 in) it starts to look compact. Below 48.6 mm (1.91 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 12 mm thick it sits within the typical range, thicker than 45% of the watches with a listed thickness.
