This weekend I got a RM010 in titanium! I figured I'd get
something that requires less commitment, before getting something like
what Jay-Z owns. 
In titanium the watch is amazingly light and comfortable. Because
of the curve of the case, I'm sure it would have still been comfortable
in platinum, but in titanium it's even more amazing. What an
incredible sports watch!
Since it's an automatic, I'm especially impressed with its
accuracy. In over a 24 hour period, it hasn't lost or gained a
second.
By the way, I was initially concerned about the case size, since 40mm
has been my limit so far. But, since this watch has no lugs and
has the curved case, it's a perfect size.
