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.

BALANCE WHEEL WITH VARIABLE INERTIA
This type of balance wheel which represents the ultimate in innovation, guarantees greater reliability when subjected to shock and also during assembly and dismantling of the movement, thus achieving better chronometric results over time. The index is eliminated, thereby allowing a more precise and repeatable adjustment using 4 setting screws.
FAST ROTATING BARREL (6 hours per revolution instead of 7.5 hours)
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.
BARREL PAWL WITH PROGRESSIVE RECOIL
This device permits an appreciable winding gain (circa 20 %), especially during the start of winding.
It also aids in the even distribution of the mainspring’s internal tension.
WINDING BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE
The wheel with a central developing profile and a pressure angle of 20° promotes rolling movement more effectively, compensates differences between centers, ensures excellent torque transmission and a distinct improvement in performance.
MODULAR TIME SETTING MECHANISM FITTED AGAINST THE CASE BACK
Provides the following advantages for longevity and maintenance:
- Since the component is mounted outside of the movement, the time setting assembly can be changed without affecting the integrity of the baseplate in the event of a possible defect or during maintenance,
- The mounting and dismantling of this module from the back will not require the removal of the hands and the dial.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE 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.
TORQUE LIMITING CROWN
This added security system prevents accidental overwinding of the watch, the result of which can cause damage such as breaking the winding stem or putting too much pressure on the barrel spring.
