Dual Time GMT Resonance 39mm

How it wears

Wears smaller than its 39 mm case suggests

Armin Strom Dual Time GMT Resonance 39mm measures 44.5 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is shorter than 75% of the 7,421 watches in this database and shorter than 57% of the 53 Armin Strom watches listed.

A flat wrist width of 50 mm (1.97 in) or more keeps it in the balanced range, and from 60 mm (2.36 in) it starts to look compact. Below 44.5 mm (1.75 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
