Richard Mille - RM038 Tourbillon Bubba Watson
American golfer Bubba Watson - the brand's latest ambassador - is the best candidate to test the comfort, lightness and extreme shock resistance of this tourbillon (HK$3.9 million). While the case is made of a rugged and light alloy named magnesium WE 54, its bottom plate, bridges and balance cock are made of titanium, which ensures rigidity critical for resisting the impact transferred to the golfer's arm from the golf club when it strikes the ball.
