Prospex 1968' Diver's Re-interpretation GMT Save the Ocean 42mm
SPB439
How it wears
Wears true to its 42 mm case size
Seiko Prospex 1968' Diver's Re-interpretation GMT Save the Ocean 42mm measures 48.6 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.16 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 12.9 mm thick it sits within the typical range, thicker than 60% of the watches with a listed thickness.
