Topic:  Rafa Nadal's Watch

Question:  Rafael Nadal is a professional tennis player.  He wears a specially made watch when he plays tennis.  

Guess the mass of the watch in grams.


Everyone knows pro athletes love their bling. But it's hard to believe some of them actually get paid to wear luxury items even when they're on the court. Check out the $525,000 RM 027 Tourbillon timepiece that tennis great Rafael Nadal is sporting at this year's French Open. With a carbon-composite case and lithium alloys, the watch weighs in at a mere 20 grams — supposedly light enough to not interfere with Nadal's game
Close up picture of the watch.

Here's a closeup of the special edition Nadal watch from Swiss watchmaker Richard Mille. Only 50 of the timepieces will be produced
