AN EXCEPTIONAL SPORTING TIMEPIECE IN PERFECT HARMONY WITH THE WORLD OF F1

Richard Mille Watches is the official partner the Lotus F1 Team since 2013, and this fruitful collaboration on F1 tracks around the globe has given birth to the first tourbillon watch dedicated to the team and especially one of the Lotus F1 Team drivers, Romain Grosjean for whom Richard Mille created this new tourbillon driven timepiece.

Main characteristics

Limited edition of 30 watches, caseband in NTPT® carbon or red gold.
Each accompanied by hand assembled 1/5th scale model of the 2014 Lotus F1 racing car.

01
CALIBER RM 50-01
Manual winding tourbillon movement with G-sensor, Hours, Minutes and Chronograph with central seconds and 30 minute counter at 9 o’clock.

FUNCTION INDICATOR In a manner similar to a car’s gearbox, the function indicator allows one to see the winding, neutral and handsetting 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 (Handsetting).

02
CALIBER RM 50-01
Manual winding tourbillon movement with G-sensor, Hours, Minutes and Chronograph with central seconds and 30 minute counter at 9 o’clock.

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.

03
CALIBER RM 50-01
Manual winding tourbillon movement with G-sensor, Hours, Minutes and Chronograph with central seconds and 30 minute counter at 9 o’clock.

G-FORCE INDICATOR This mechanism was designed to visually display the number of the G’s accumulated by the watch’s wearer during rapid deceleration. The hand and scale located below 12 o’clock indicate whether the deceleration is mild (green zone) or critical (red zone) for the driver.

04
CALIBER RM 50-01
Manual winding tourbillon movement with G-sensor, Hours, Minutes and Chronograph with central seconds and 30 minute counter at 9 o’clock.

CASE RM50-01

The bezel and the caseback are in NTPT® carbon, an exclusive material with a unique appearance. Its remarkable surface displays extremely regular undulations, as NTPT® carbon is composed of multiple layers of parallel filaments obtained by dividing carbon fibers. These layers, with a maximum thickness of 30 microns, are impregnated with resin then woven on a special machine that modifies the direction of the weft by 45° between layers, creating this distinctive visual effect that is strongly reminiscent of Damascene steel. Heated to 120°C at a pressure of 6 bars, the NTPT® is then ready to be processed on a CNC machine in Richard Mille’s Proart case factory. When compared to composite materials, whose exceptional physical properties are already well known, NTPT® carbon improves the rate of occurrence of breaking stresses by 25% and of micro-cracks by 200%. The case of the RM 50-01 is water resistant to 50 meters, ensured by two Nitril O-ring seals. The case is assembled with 20 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel.

BRIDGES MADE IN GRADE 5 TITANIUM AND STAINLESS STEEL RM50-01

The bridges of the caliber RM50-01 are made of grade 5 titanium. To give more depth to the caliber, some bridges, such as the tourbillon and G-sensor bridges and certain components, such as the chronograph mechanism and the clutch rocker, are made of stainless steel and given a golden appearance by galvanization treatment.

CHRONOGRAPH RM50-01

The modern architecture of this new movement has allowed for a coherent and rational arrangement of each constituent part, avoiding unnecessary complexity and permitting the best possible use of the functions with technical solutions. For example, research was conducted into the geometric design of the column wheels that control the different levers in order to ensure the perfect, long-term, stable and simultaneous functioning of the chronograph mechanism, a feature that is essential for a high performance chronograph. Operation: the chronograph function is stopped and started via the pusher located on the lower left at 8 o’clock. The hands are reset by pressing another pusher located on the upper left at 10 o’clock.

SKELETONISED TITANIUM BASEPLATE RM50-01

The baseplate has been finished in grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% grade 5 titanium, 6% aluminium and 4% vanadium. This combination further increases its mechanical properties, which explains its frequent use in the aerospace, aeronautical and automobile industries. The baseplate of the caliber RM50-01 has been optimized to achieve an extreme weight/resistance ratio.

Characteristics

FREE SPRUNG BALANCE 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.
