Bianchet B 1.618 UltraFino 40mm

How it wears

Wears true to its 40 mm case size

Bianchet B 1.618 UltraFino 40mm measures 47.39 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is longer than 56% of the 8,093 watches in this database and longer than 0% of the 29 Bianchet watches listed.

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 47.39 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 9.9 mm thick it is on the slim side, thinner than 84% of the watches with a listed thickness.
