Biver Automatique 39mm

How it wears

Wears larger than its 39 mm case suggests

Biver Automatique 39mm measures 47.55 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.22 against a database median of 1.18. That span is longer than 59% of the 8,093 watches in this database.

A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 47.55 mm (1.87 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 mm thick it is on the slim side, thinner than 82% of the watches with a listed thickness.
