After making the RM 036 Jean Todt, whose objective was to promote civic responsibility by encouraging drivers to adopt a more relaxed driving style, it seemed logical we should make a product designed for pure competitive racing.
Who other than Sébastien Loeb could have embodied the use of this extreme-racing watch?
Limited edition of 30 pieces.
Rotating bezel: TZP brown ceramic made of aluminium oxide powder tubes injected at a pressure of almost 2,000 bar. It is noted for being a particularly scratch resistant material (1,400 Vickers), possessing a stable color.
Brown ceramic requires a long and difficult machining and grinding process using special diamond tools
Caseband: made from an extremely strong anthracite polymer injected with carbon nanotubes.
This combination produces a material that provides perfect protection for the movement and the tourbillon
Caseback and fixed bezel: grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy.
It is composed of 90% titanium, 6% aluminium and 4% vanadium, a combination that further enhances the mechanical properties of the material
The design and execution of the watch demonstrates a complete conceptual approach to the movement, case and dial. As a result, everything has been constructed according to extremely rigorous specifications, 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 three-part case is water resistant to 30 metres 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.
Manual winding tourbillon movement with hours, minutes.
Rotary g-sensor, power reserve indicator and function selector.
Composed of over 50 parts and measuring a mere 17 mm, 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.
The g-sensor system operates on the principle of displacement of a weight, and a hand above the scale indicates whether the number of g’s accumulated is mild (green zone) or critical (red zone) for the driver.
A push-piece set at the centre of the sapphire glass quickly resets it to zero.
In a manner similar to a car’s gearbox, a push-button located at 4 o’clock one to select the winding, neutral and hand setting functions with a simple push.
A small hand near at 4 o’clock displays the selected function:
W (Winding) – N (Neutral) – H (Hand Setting).
Anglage and polishing by hand
Locking sections hand polished
Sapphire blasted milled sections
Lapped and polished contact points
Burnished pivots Steel parts
Sapphire blasted surfaces
Anglage and polishing by hand
Drawn outer faces Wheels
Concave chamfering with a diamond tool
Rhodium plating (before cutting the teeth)
Minimal corrections are made to the wheels to preserve their geometry and overall performance.
Variable inertia, free sprung balance
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shock and also during movement assembly and disassembly, hence better chronometric results over time. The regulator index has been eliminated and a more accurate and repeatable adjustment is possible thanks to 4 small adjustable weights located directly on the balance.
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.
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.
