Prospex 1968 Heritage Diver's GMT Watch 41mm
SPB317
How it wears
Wears true to its 41 mm case size
Seiko Prospex 1968 Heritage Diver's GMT Watch 41mm measures 46.9 mm lug-to-lug on a 41 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is shorter than 53% of the 7,421 watches in this database and shorter than 42% 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 63 mm (2.48 in) it starts to look compact. Below 46.9 mm (1.85 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 12.3 mm thick it sits within the typical range, thicker than 51% of the watches with a listed thickness.
