Rafael Nadal’s newest piece of equipment costs more than three-quarters of a million dollars, and yet it will probably never help him win a tennis tournament.

Nadal upgraded his on-court wrist watch to a $US775,000 model made by Richard Mille for the French Open, Robert Frank of CNBC reports.

Nadal is no stranger to the world of high-end watches. In 2010 he began wearing another Richard Mille timepiece valued at $US500,000. In 2013, he was wearing the predecessor to his current watch, one valued at $US690,000.

Richard Mille will only make 50 of the RM27-02. Its most impressive feature is its lightweight (20 grams) yet durable construction (which can withstand 5,000 Gs of force).

Nadal, who’s left-handed, wears it on his right wrist:
