BR-X2 Tourbillon Micro-Rotor, Unusual & Technical 42.5mm

How it wears

Wears smaller than its 42.5 mm case suggests

Bell & Ross BR-X2 Tourbillon Micro-Rotor, Unusual & Technical 42.5mm measures 42.5 mm lug-to-lug on a 42.5 mm case, a lug-to-lug ratio of 1.00 against a database median of 1.18. That span is shorter than 85% of the 7,421 watches in this database and shorter than 37% of the 49 Bell & Ross watches listed.

A flat wrist width of 48 mm (1.89 in) or more keeps it in the balanced range, and from 57 mm (2.24 in) it starts to look compact. Below 42.5 mm (1.67 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
