Tennis star Rafael Nadal and Swiss watch manufacturer Richard Mille have teamed up to auction the Rafael Nadal RM27-02 tourbillon prototype. Proceeds from the sale at theOnly Watch auction on 7 November in Geneva will be donated to research in preventing Duchenne muscular dystrophy.

In its sixth year, the auction will see the prototype accompanied by the autographed outfit that the tennis champion wore during the US Open. Having worn the timepiece in 2015 throughout the US Open and some of the biggest Grand Slam tournaments such as the French and US Opens, Nadal helped the watchmaker refine and complete the design and functionality of the watch.

The auction will also be an opportunity for the Swiss watch manufacturer to unveil the first skeletonized baseplate known as the 'unibody'. Taking its inspiration from the bodywork of race cars and built from NTPT carbon, it ensures rigidity and shock-resistance. Seen on Nadal with a bright orange strap, the timepiece is built not only to last but also to be seen.


The Only Watch auction will take place in Geneva on 7 November 2015.
