Seiko Prospex Landmaster 30th Anniversary SLA071 42mm

How it wears

Wears true to its 42 mm case size

Seiko Prospex Landmaster 30th Anniversary SLA071 42mm measures 50.1 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is longer than 87% of the 8,010 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 67 mm (2.64 in) it starts to look compact. Below 50.1 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 12.7 mm thick it sits within the typical range, thicker than 59% of the watches with a listed thickness.
