Richard Mille RM 17-01 Tourbillon Carbon TPT 40.1mm

How it wears

Wears true to its 40.1 mm case size

Richard Mille RM 17-01 Tourbillon Carbon TPT 40.1mm measures 48.15 mm lug-to-lug on a 40.1 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is longer than 69% of the 8,010 watches in this database and longer than 45% of the 38 Richard Mille watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 65 mm (2.56 in) it starts to look compact. Below 48.15 mm (1.90 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 13.8 mm thick it is on the thicker side, thicker than 79% of the watches with a listed thickness.
