Richard Mille RM 21-02 Tourbillon Aerodyne 42.68mm

How it wears

Wears true to its 42.68 mm case size

Richard Mille RM 21-02 Tourbillon Aerodyne 42.68mm measures 50.12 mm lug-to-lug on a 42.68 mm case, a lug-to-lug ratio of 1.17 against a database median of 1.18. That span is longer than 87% of the 8,093 watches in this database and longer than 86% of the 37 Richard Mille 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 50.12 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.

At 14.3 mm thick it is on the thicker side, thicker than 86% of the watches with a listed thickness.
