Richard Mille 020
This thing is sick, I'm not exactly sure on the weight, but the RM wristwatch that was misplaced by that tennis star weighed twenty grams(not including the strap)
To give you an idea of what that is, it's less than four quarters, and a Rolex Submariner is probably 120-140 grams.
$450k
The 4 indicator is supposed to be function, meaning neutral(in) H is hands(out) and W(wind) but it says R, I'm not exactly sure.
In any case, holy crap.
