Brazilian Formula 1 driver Felipe Massa is the first sporting figure to have joined the Richard Mille family. A long-time test driver for Richard Mille watches, it was he who enabled the brand to initiate and accomplish astonishing feats in watchmaking development. Renowned by experts for its uncompromising technicality, at the very core of the RM 056 tourbillon caliber is a synthesis of the brand’s most exciting innovations. Comprised of more than 500 individual components, the grade 5 titanium RMCC1 caliber plays host to one of horology’s most exquisite complications: a split-seconds chronograph. This tourbillon movement also boasts indicators for the power reserve and torque, and a function selector. As meticulous in their craft as Felipe Massa in his own sphere, the engineers at Richard Mille have optimized the movement, fine-tuning its time-keeping precision and improving the operation of its split-seconds by reducing friction, and ensuring the long-term reliability of the caliber.
Often imitated, but never equaled, this tour de force of style and engineering represented a considerable challenge: machining sapphire is an exceedingly complex procedure, requiring no less than 1000 hours of work for each case, including 430 hours of filing and 350 hours of polishing for the bezel, case middle and case-back ensemble. Limited Edition of 10.
TORQUE INDICATOR Supplies information about the mainspring’s tension, thus permitting the optimalization of the chronometric functioning of the movement. Below 53 dNmm, the spring is considered to be too slack, while above 65 dNmm, the excessive spring tension can adversely affect the mechanism’s operation, or else actually endanger it. These indications appear on the numerical zone to the right of the barrel.
FUNCTION SELECTOR In a manner similar to a car’s gearbox, the function indicator allows one to see the winding, neutral and hand setting positions as the crown is pulled out. Each position is indicated via a hand at 4 o’clock displaying the following functions: W (Winding) – N (Neutral) – H (Hands).
CHRONO COMPETITION MOVEMENT The RMCC1 movement is inspired by the tourbillon caliber with split-seconds chronograph from the RM008. Released in 2004, this caliber has established itself as one of the most complex in the world thanks to its tourbillon movement operating a split-seconds chronograph. The caliber RMCC1 is not just a simple exercise based on the movement of the RM008. Richard Mille’s engineers spent several months reducing the weight of the caliber. This is a delicate operation when you consider that the weight of the caliber RMCC1 has been cut by 20% compared with the RM 008 to bring it under 10 grams. This required the reworking and manufacture of over 400 parts in the movement. At the same time our engineers have optimized this movement to the maximum, particularly in terms of its time-measuring precision and long-term reliability.
