Tourbillon B1.618 Openwork 43mm
B1.618
How it wears
Wears true to its 43 mm case size
Bianchet Tourbillon B1.618 Openwork 43mm measures 50 mm lug-to-lug on a 43 mm case, a lug-to-lug ratio of 1.16 against a database median of 1.18. That span is longer than 82% of the 7,421 watches in this database and longer than 31% of the 29 Bianchet watches listed.
A flat wrist width of 56 mm (2.20 in) or more keeps it in the balanced range, and from 67 mm (2.64 in) it starts to look compact. Below 50 mm (1.97 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.

Fit reference
Fills most of the wrist for a bold, sporty fit; lug shape and end links matter.
