Reservoir Hydrosphere Air Gauge 45mm

How it wears

Wears smaller than its 45 mm case suggests

Reservoir Hydrosphere Air Gauge 45mm measures 45 mm lug-to-lug on a 45 mm case, a lug-to-lug ratio of 1.00 against a database median of 1.18. That span is shorter than 70% of the 8,093 watches in this database.

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 45 mm (1.77 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
