Prospex 1965 Divers Modern Reinterpretation 40.5mm
SPB421
How it wears
Wears true to its 40.5 mm case size
Seiko Prospex 1965 Divers Modern Reinterpretation 40.5mm measures 47.6 mm lug-to-lug on a 40.5 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is longer than 59% of the 7,413 watches in this database and longer than 69% of the 390 Seiko watches listed.
A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 47.6 mm (1.87 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.
