Khaki Navy Scuba Auto 40mm

How it wears

Wears larger than its 40 mm case suggests

Hamilton Khaki Navy Scuba Auto 40mm measures 52 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.30 against a database median of 1.18. That span is longer than 94% of the 7,413 watches in this database and longer than 79% of the 80 Hamilton watches listed.

A flat wrist width of 58 mm (2.28 in) or more keeps it in the balanced range, and from 70 mm (2.76 in) it starts to look compact. Below 52 mm (2.05 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.
