Jazzmaster Thinline Auto 40mm
H38525881
How it wears
Wears true to its 40 mm case size
Hamilton Jazzmaster Thinline Auto 40mm measures 46 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is shorter than 59% of the 7,413 watches in this database and shorter than 64% of the 80 Hamilton watches listed.
A flat wrist width of 52 mm (2.05 in) or more keeps it in the balanced range, and from 62 mm (2.44 in) it starts to look compact. Below 46 mm (1.81 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 8.45 mm thick it is on the slim side, thinner than 93% of the watches with a listed thickness.
