The new RM 36-01 G-Sensor Tourbillon Sébastien Loeb is the result of the collaboration between Richard Mille and Sébastien Loeb, the most successful driver in WRC history, having won the world rally championship a record nine times in a row and set the new world record on the Pikes Peak Hill Climb in 2013.
The key to understanding this new creation can be gleaned from the rotating brown ceramic bezel: the G-force sensor can now be rotated manually to align in different directions, enabling drivers to view the lateral deceleration as well as longitudinal forces found respectively in corners, acceleration and braking on straights.
Directly connected to the bezel and sapphire glass, the sensor can indicate G-forces of up to 6 G’s.
Created in a limited edition of 30 pieces, Sébastien Loeb wears this exceptional timepiece during WTCC competitions and on all other motorsport events in which he will participate.
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).
BASEPLATE AND BRIDGES IN 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 % grade 5 titanium, 6% aluminum and 4 % vanadium.
ROTARY G-SENSOR Composed of over 50 parts and measuring a mere 17mm, the rotary G-sensor is designed to visually display the number of G’s accumulated by the driver during the different phases of driving such as rapid acceleration, deceleration and lateral forces. The direction of the G-force to be recorded is set by rotating the bezel. A needle on the scale indicates whether the number of Gs accumulated is mild (green zone) or critical (red zone). A push-piece set at the center of the sapphire glass quickly resets it to zero.
CALIBER RM 36-01 Manual winding tourbillon movement with hours, minutes, rotary G-sensor, power reserve indicator and function selector.
FREE SPRUNG BALANCE WITH VARIABLE INERTIA
The free-sprung balance with variable inertia and a terminal-curve spring guarantees greater reliability in case of impacts and during movement assembly and disassembly, thus achieving better chronometric results over time.
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 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 baseplate in the event of a possible defect or during maintenance, - The mounting and dismantling of this module from the back will not require there moval of the hands and the dial.
WHEEL BASED TIME SETTING SYSTEM (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.
