Bubba Watson wears the Richard Mille RM055.
Richard Mille is a brand of swiss made luxury watches founded by French businessman Richard Mille (go figure) in 1999 in conjunction with Audemars Piguet.
Gerry “Bubba” Watson is an American Professional golfer and one of the few left handed golfers on the PGA Tour. Watson was raised in Florida where he played golf on his high school team. In 2003 he turned professional and got a spot on the National Tour, and then in 2005 he qualified for the PGA Tour.
The RM055 is a luxury sports watch designed by Richard Mille for Bubba Watson. The watch case is rubberized titanium and features a rubber strap. It is skeletonized, which always makes watches hard to read for me, but that may be your thing. The watch has a scratch and glare resistant sapphire crystal and is water resistant to 30 meters. It is an automatic self-winding watch.
You can check out the RM055 on the Richard Mille Website.
