Pro tennis player, Rafael Nadal, just won his fifth French Open in six years, and he did so in dominant fashion. The 24-year old has also regained the world No. 1 ranking, supplanting Roger Federer. This win is also a win for watchmaker Richard Mille. As you can see from the photo, Nadal is wearing the Richard Mille RM 027 Tourbillon. He actually wears this timepiece during his matches.

The RM 027 is unobtrusive and does not interfere with his game, clearly, as he has just won his first major since he signed on as a Richard Mille ambassador. The watch he wears during all of his tournaments is not your average sports watch either, it costs over half of a million dollars and was custom built with input from Nadal. It’s extremely light and has special shock absorbers, which prevent damage to the delicate tourbillon mechanism.
