Eagle-eyed tennis fans might have spotted something odd about Raphael Nadal's win in May’s French Open: he was wearing a wristwatch. Whether fluffing shots at your local club or throwing yourself around Roland Garros, a tennis court is an inherently unsuitable environment for a timepiece. But now the maverick watchmaker Richard Mille has created the first watch designed for the sport in the form of his RM 027.

Made from a combination of titanium, aerospace-quality LITAL alloy and carbon composite, it weighs less than 20g - including the specially-designed polycarbonate strap. And, in what can only be described as a gesture of extreme confidence, Mille has incorporated the notoriously intricate and delicate complication of a tourbillon escapement into the movement.
