Andy Murray, Britain’s number one tennis player, currently ranked fourth in the world, has signed on as an Ambassador with Swiss watch brand Rado.

The announcement was made ahead of the Aegon Championships, of which Rado is Official Watch Partner and Timekeeper.

Murray will wear the Rado D-Star 200 Automatic, a blue high-tech ceramic timepiece and the same watch as is sponsoring Queens.

“I’m really excited about joining the Rado team. The brand is all about edgy style and performance. Timing, precision and accuracy are vitally important for me, whether that relates to fitness drills, measuring my performance or striking a tennis ball.”

He will also become the face of the D-Star 200 collection for summer 2012.

Murray has won 22 career ATP titles and in 2011 became only the seventh player since 1968 to reach the semi-finals of all four Grand Slam tournaments in one year.
