Hamilton Chrono-Matic 50 Auto Chrono Limited Edition 48.5mm
H51606640
How it wears
Wears smaller than its 48.5 mm case suggests
Hamilton Chrono-Matic 50 Auto Chrono Limited Edition 48.5mm measures 51.5 mm lug-to-lug on a 48.5 mm case, a lug-to-lug ratio of 1.06 against a database median of 1.18. That span is longer than 93% of the 8,010 watches in this database and longer than 76% 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 69 mm (2.72 in) it starts to look compact. Below 51.5 mm (2.03 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 16.05 mm thick it is on the thicker side, thicker than 97% of the watches with a listed thickness.
