Developed in collaboration with Rafael Nadal who tested this watch in real world conditions and who will wear it during matches
La Cote des Montres - April 2nd, 2010
The introduction of the new RM 027 Tourbillon marks the brand’s first entry to the world of tennis courts. As with Felipe Massa who drives every F1 Grand Prix with his watch, Rafael Nadal will play all of his matches wearing his Richard Mille on his wrist, an extraordinary feat.
Following the RM 006 (42 g without strap) and the RM 009 (29 g without strap), the RM 027 weighs in at less than 20 g (including the strap) thus becoming one of the lightest watches ever produced.
Fascinated by the combination of technology, performance and practical aspects in a wristwatch, Richard Mille wished to prove once more that an extreme reduction in weight could be achieved with total efficiency and accuracy. It is from this key concept that he developed the RM 027 Tourbillon in close collaboration with Rafael Nadal, who tested the RM 027 in real world conditions and will now wear it during tennis matches. The results of this horological experiment speaks for itself: despite the abrupt, extreme movements and shocks typical of high level tennis matches, the RM 027 Tourbillon has proven its durability whilst enabling Rafael Nadal total freedom of movement.
The movement baseplate of the RM 027 Tourbillon is made from Titanium and LITAL®alloy, a high lithium content alloy containing aluminum, copper, magnesium and zirconium, possessing a density of 2.55. The addition of Lithium, one of the lightest elements, to the alloy mixture, provides great strength without adding unnecessary weight. This particular alloy is also used for the same reasons in the aerospace industry in the construction of the Airbus A380, helicopters, rockets and satellites, as well as in F1 racing cars.
The RM 027 watchcase, composed of a composite containing large amounts of carbon, provides a tough and resilient enclosure for the tourbillon movement at its center. The back bezel and caseband are monobloc to ensure total lightness. The glass; the bezel and the flange in carbon have remarkable properties of stiffness and torsional rigidity.
The RM 027 Tourbillon is a limited edition of 50 pieces with an ultra light strap in polycarbonate, flexible and extremely comfortable.

Technical specifications
Caliber RM 027: manual winding tourbillon movement with hours and minutes.
Dimensions: 48 mm x 39.70 mm x 11.85 mm
Weight of the movement: 3.83 g
Weight of the watch without strap: circa 13 g
Main features (many of which are major technical innovations)
The movement of the RM 027 Tourbillon is made from titanium and LITAL®alloy, a high lithium content alloy containing aluminium, copper, magnesium and zirconium, possessing a density of 2.55 g cm3. The addition of Lithium provides to the mechanism more flexibility and greater shock resistance. This alloy is also applied in aerospace on the Airbus A380, helicopters, rockets, satellites as well as in Formula 1.
Power reserve
48 hours.
Variable inertia, free sprung balance
The free-sprung balance gives better reliability in the event of shocks, movement assembly and disassembly, and also guarantees better chronometric results over an extended period of time.
Fast rotating barrel (6 hours per revolution instead of 7,5)
This type of barrel provides the following advantages:
- the phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance;
- provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.
This device permits an appreciable winding gain (circa 20 %), especially during the start of winding.
It also promotes the even distribution of the mainspring’s internal tension.
Spline screws in grade 5 titanium for the bridges and case
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
Winding barrel teeth and third-wheel pinion with central involute profile
The central involute profile of the winding barrel teeth and pinion provide an optimal pressure angle of 20°. This promotes effective rotary motion and allows for compensation of possible variations in the engagement of the going train, thus insuring excellent torque transmission with a distinct improvement in performance.
Case
The RM 027 watchcase, composed of a composite containing large amounts of carbon, provides a tough and resilient enclosure for the tourbillon movement at its center. The back bezel and caseband are monobloc to ensure total lightness. The glass, with anti-glare treatment, has remarkable properties of stiffness and torsional rigidity.
