Jazzmaster Open Heart Lady Auto 34mm

How it wears

Wears true to its 34 mm case size

Hamilton Jazzmaster Open Heart Lady Auto 34mm measures 40 mm lug-to-lug on a 34 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is shorter than 92% of the 7,421 watches in this database and shorter than 94% of the 80 Hamilton watches listed.

A flat wrist width of 45 mm (1.77 in) or more keeps it in the balanced range, and from 54 mm (2.13 in) it starts to look compact. Below 40 mm (1.57 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 10.64 mm thick it is on the slim side, thinner than 80% of the watches with a listed thickness.
