Richard Mille RM 4 Tourbillon Rafael Nadal Watch. To commemorate the 10th annive

Richard Mille RM 4 Tourbillon Rafael Nadal Watch. To commemorate the 10th anniversary of the brand's partnership with Rafael Nadal, Richard Mille has just launched a new watch with a very tennis-inspired style, the RM 4 Tourbillon Rafael Nadal. The hollow design is inspired by a tennis racket, and the entire watch once again breaks the design limits of professional sports watches; the barrel-shaped case has a novel design with a distinct sense of layering, and Nadal's nickname - Rafa - is engraved on the side; the new watch does not use a traditional dial, but imitates the production principle of a tennis racket. A thin steel cable with a diameter of only 0.27mm is woven into a grid and hung inside the case. The movement is then fixed to the grid with a metal hook. This design is not only lightweight, but also can buffer the impact of high-intensity impact on the movement; steel cable grid dial, hollow hands.
