Richard Mille RM 07-04 Automatic Sport 30.5mm

How it wears

Wears larger than its 30.5 mm case suggests

Richard Mille RM 07-04 Automatic Sport 30.5mm measures 44.95 mm lug-to-lug on a 30.5 mm case, a lug-to-lug ratio of 1.47 against a database median of 1.18. That span is shorter than 74% of the 8,093 watches in this database and shorter than 97% of the 37 Richard Mille watches listed.

A flat wrist width of 50 mm (1.97 in) or more keeps it in the balanced range, and from 60 mm (2.36 in) it starts to look compact. Below 44.95 mm (1.77 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 10.35 mm thick it is on the slim side, thinner than 80% of the watches with a listed thickness.
