RICHARD MILLE - RM 036 TOURBILLON G-SENSOR JEAN TODT
LIMITED AND NUMBERED EDITION OF 15 PIECES
SIHH 2013 - Salon International de la Haute Horlogerie
The SIHH will take place in Geneva this month.
Jean Todt is a French motor sport executive, and currently the President of the Federation Internationale de l’Automobile (FIA).
Previously, Todt was CEO of Ferrari Motorsports and began his career as a rally driver with the Peugeot Talbot Sport team.
Richard Mille has created this limited edition timepiece in his honor.
The RM 036 TOURBILLON G-SENSOR JEAN TODT
In addition to the lightweight architecture and large tourbillon that you're no doubt familiar with, Mr. Mille has added a G-Force sensor to the RM036.
With the thick (16.15mm to be precise) tonneau shaped case that Richard Mille is known for, this time crafted from lightweight titanium.
Inside is a skeletonized carbon nano fiber baseplate, grade 5 titanium bridges, rigidified arcap central bridge, and the usual Richard Mille spline screws holding everything together.
The idea here is to maximize rigidity and longevity of performance, even under harsh conditions.
The tourbillon has a free spung variable inertia balance, which helps the watch maintain accuracy after suffering shocks, and the barrel is both fast-rotating and has progressive recoil, making the force delivered more constant over time.
The centerpiece is the G-Force recorder, the first in a Richard Mille watch.
In the event of rapid deceleration, the amount of G-Force experienced by the wearer is displayed at 12 o'clock.
The scale is graded from green to red, alerting the wearer as to whether or not the amount of force is safe for the human body.
To reset the meter at any time, you just pump the push-piece at 9 o'clock.
The crown at 3 o'clock also has a push-piece in the center, which allows you to select winding, neutral, and hand-setting modes.
At 4 o'clock there is a small display marked W N H, so you never have to wonder which mode you're in.
A simple push and the needle jumps to the next mode.
Additionally, the module for setting the time is actually located behind the rest of the movement, making repairs easier and less invasive should they be needed.

SKELETONIZED CARBON NANOFIBER BASEPLATE
This is an isotropic composite material created from carbon nanofibers with high mechanical, physical and chemical stability in all directions.
The ribbed perimeter of the movement plate assures the highest rigidity between the baseplate and bridges.
Carbon nanofiber composite structures such as this are amorphous, chemically neutral and dimensionally constant within a very wide range of operating temperatures, including those outside of normal ranges.
This stability assures the highest integrity of the movement's going train under all conditions.
The skeletonized baseplate and the bridges have been subjected to intensive and complete validation tests to optimize their resistance capacities.
BRIDGES MADE OF GRADE 5 TITANIUM
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% 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.
This complex mechanism was designed to visually display the number of Gs accumulated by the watch's wearer during rapid decelerations The scale located at 12 o'clock, whose needle indicates whether the deceleration is safe (green zone) or critical (red zone) for the driver. A push-piece at 9 o'clock quickly resets it to zero.
In a manner similar to a car's gearbox, a push-button located at the center of the crown allows one to select the winding, neutral and hand setting functions with a simple push.
A hand at 4 o'clock displays the selected function: W (Winding) – N (Neutral) – H (Hands)
FREE SPRUNG BALANCE WITH VARIABLE INERTIA
It guarantees greater reliability when subjected to shock and also during movement assembly and disassembly, hence better chronometric results over time.
The regulator index is eliminated and a more accurate and repeatable adjustment is possible thanks to 4 small adjustable weights located directly on the balance.
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, 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 a profitable winding gain (circa 20 %), especially during the winding start. It is also helpful in the distribution of the mainspring's internal tension.
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 bottom plate 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.
WHEEL BASED TIME SETTING SYSTEM
On back of the movement:
Provides smooth time setting functions through the elimination of engaging friction by replacing it with rolling friction.
CERAMIC ENDSTONE FOR THE TOURBILLON CAGE
This reflects a technical and long-term view towards the elimination of wear phenomena, resulting in improved technical tribology.
CENTRAL BRIDGE IN RIGIDIFIED ARCAP
Ensures high rigidity of the baseplate and the bridge assembly of the going train.
WINDING BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE
The central involute profile of the winding barrel teeth and pinion provides 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.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES
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.
The design and execution of the entire watch bears witness to a complete conceptual approach regarding the movement, case and dial.
As a result, everything has been constructed according to an extremely rigorous specification, in the manner of the analytical engineering methods used in the design of Formula 1 racing cars where the chassis and the engine are developed in complete harmony.
The case of the RM 036 requires 86 stamping operations, of which 49 make up the striking of the three principal components (bezel, case middle and case back), before the cutting and milling can start.
It takes 20 hours to set a machine and 30 hours of programming to produce just a single kit.
The case requires 255 machining operations and the finishing phase involves 5 hours of satin finishing and polishing.
A five-axis machining centre (perfected machine) must be used to create the case's complex form.
For each case machined, a period of 45 minutes is needed just for the positive engraving of the name "Richard Mille".
The tripartite case 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.
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.
