Why Rafael Nadal Needs An Even Lighter $690,000 Watch For Tennis - Forbes
Nadal's new watch, which is 1 gram lighter than his previous one, and $165,000 more expensive.
Grand total of $690,000.
I don't care what he wears on his wrist, as long as he stays healthy, starts winning again and hopefully reclaims the French title.
