RM 27-01TOURBILLON RAFAEL NADAL

FAST ROTATING BARREL (6 hours per revolution instead of 7.5 hours)This type of barrel has the following advantages:- The phenomenon of periodic internal mainspring adhesion is significantly diminished and performance is thus enhanced,- It provides an excellent delta of the mainspring curve. The choice is determined by the idealpower-reserve/performance/regularity ratio.BARREL PAWL WITH PROGRESSIVE RECOILThis 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.WINDING BARREL TEETH AND CENTRE-WHEEL PINION WITH CENTRAL INVOLUTE PROFILEThe central involute profile of the winding barrel teeth provides an optimal pressure angle of 20°, which promoteseffective rotary motion and compensates for possible variations in the operation of the going train. This, in turn,ensures excellent torque transmission and a distinct improvement in performance.SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGESThis permits better control of the torque applied to the screws during assembly. These screws are therefore unaffectedby physical manipulation during assembly or disassembly and age well.OTHER FEATURES- Movement dimensions: 27.20 mm x 21.72 mm- Thickness: 5.04 mm- Tourbillon diameter: 12.30 mm- Balance diameter: 10.00 mm- Number of jewels: 19- Balance: in Glucydur, with 2 arms and 4 setting screws- Moment of inertia: 11.50 mg.cm 2 , angle of lift 53°- Frequency: 3 Hz (21,600 vph)- Balance spring: in ELINVAR by Nivarox ®- Shock absorbers: Kif Elastor by KE 160 B28- Barrel shafts: in nickel-free Chronifer (DIN x 46 Cr13 + S), with the following characteristics: stainless, non-magnetic,tempered.CASEThe case of the RM 27-01 is made from an extremely strong anthracite polymer injected with carbon nanotubes. Thiscombination produces a material that protects the movement and the tourbillon positioned inside it against impacts.The caseband and case back feature monobloc constructions for evermore improved lightness and rigidity.The crystal, with its anti-reflective treatment, has remarkable properties that ensure extreme toughness and optimumrigidity.

THE TOURBILLON RM 27-01 RAFAEL NADAL WATCHThe partnership between Rafael Nadal and Richard Mille has led to a string of successes, on the courts forthe Majorcan tennis champion, notably with his 7 th successive victory at the French Open in 2012, and in thewatchmaking sphere for Richard Mille, with the Tourbillon RM 027 Rafael Nadal timepiece, renowned for itsextreme lightness, or the Chronofiable ® certified RM 035 Rafael Nadal, which can resist accelerations of over5,000 G without detriment to any aspect of its performance.In 2013, Richard Mille will present the Tourbillon RM 27-01 also designed in collaboration with Rafael Nadal. Anexceptional creation, it pushes the concepts of lightness and strength to the ultimate extreme.The caliber RM27-01 is a triumph of engineering and technology. Its complex, original architecture is the resultof Richard Mille’s determination to create a movement held in total suspension in the heart of its case. Inspiredby suspended civil engineering infrastructures, Richard Mille wanted to adapt these modes of constructionto the watchmaking sphere, occupying a space of just a few tens of millimetres. After many months ofdevelopment, Richard Mille’s movement engineers gave tangible form to this avant-garde concept, positioningit indisputably as one of the most innovative architectural constructions of recent years.The RM 27-01 Rafael Nadal has a baseplate attached to the case by four braided steel cables just 0.35 mmin diameter. This structure combines strength and flexibility to protect the movement, which weighs just 3.5grammes, thanks to the use of grade 5 titanium for the baseplate and tourbillon carriage, and of aluminiumlithiumfor the barrel bridges and gear-trains.These cables are held taut by means of an ingenious mechanism of tensioners (located at 3 and 9 o’clock)and pulleys, which act like pylons positioned at the four corners of the movement. Each cable is fixed to thetensioner, and passes over the upper pulley and into the movement, before returning via the lower pulley tofinish in the lower flange. Once the watchmaker has threaded the cables, he tensions them by rotating thecentral tensioner ring with a special tool.The installation and tensioning of the cables are extremely delicate operations. Excessive tension could breakthe cables and attachments at any time and damage the movement, while insufficient tension could put themovement into a resonance phase, disturbing its chronometric performance.Designed to stay in suspension inside its case, this exceptional caliber can withstand accelerations of over5,000 G.The RM 27-01 weighs just 19 grammes, Velcro ® strap included. This feat was made possible by the materialselected for the case. Carbon has the place of honour in the composition of the RM 27-01’s case, which featuresa monobloc back. Its anthracite colour is due to the high concentration of carbon nanotubes. The result: perfectresistance to shocks and scratches, and the comfort that is vital to Rafael Nadal during his tournaments, all ofwhich he now plays with an RM 27-01 on his wrist.The RM 27-01, available in carbon nanotubes and supplied on a Velcro ® strap, is available in a limited edition of50 timepieces.
