For US$525k, I could get myself a Mercedes S600 V12, a matching pair of Rolex Platinum and still have enough money to buy my dream system. Maybe you are right about the "real deal" as after all, the watch had his name "Nadal" inscribed on the dial.
I suppose when one is at the pinnacle, one can almost afford anything. Just look at Footballers, Basketball players ..... Tennis is relatively small in comparison in earnings.
Cant be envy all the time. Back to reality .... go watch Roland Garros now .......
