Astron Seiko 145th Anniversary Limited Edition 43.4mm

How it wears

Wears true to its 43.4 mm case size

Seiko Astron Seiko 145th Anniversary Limited Edition 43.4mm measures 50 mm lug-to-lug on a 43.4 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is longer than 82% of the 7,413 watches in this database and longer than 92% 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 67 mm (2.64 in) it starts to look compact. Below 50 mm (1.97 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 12.4 mm thick it sits within the typical range, thicker than 53% of the watches with a listed thickness.
