Rafael Nadal and Richard Mille
While some partnerships are purely professional, the relationship between Spanish champion Rafael Nadal and Richard Mille has become a solid friendship. The 13-time French Open winner designed a watch with the avant garde brand to mark the 10th anniversary of their partnership.
Dubbed the RM 27-04, the ultra-engineered tourbillon has a dial that resembles a tennis racket. Limited to just 50 pieces, each unit costs over $1 Million. (photo: Richard Mille)
