Montre concept Cartier ID Two

The case in Ceramyst reveals the revolutionary mechanism of the id Twoo Cartier.

This innovative new-generation material is the first transparent polycrystalline ceramic offering designers complete freedom of creation. The case in Ceramyst TM offers a fine view of each of the movement’s components coated in matte black with another cutting-edge material : ADLC.

Some facts:

1.Vacuum case

To shield the oscillator from air resistance as it beats, the interior of the single-block case/glass in Ceramyst™ transparent ceramic is a vacuum. Airtightness is reinforced by using gaskets doped with nanoparticles.

2.Barrels with double fiberglass springs

For the first time in watchmaking history, the springs providing energy to the watch movement have been made not in metal, but in glass microfiber, giving a considerable increase in power.

3. DRIE technology

DRIE technology (Deep Reactive Ion Etching) allows micromechanical components to be made with extreme precision (to the nearest micron) and lends itself particularly well to carbon crystal.

4.

Differential gearing

The differential gear train with ultra-light components works without lubrication, minimizes friction and offers an optimized reduction ratio.

5.ID Escapement

Cartier ID Two reuses the solution explored in Cartier ID One: components made using DRIE technologies, oscillator and escapement bearing in carbon crystal, and pivot axes in black ADLC- coated titanium.

6.ADLC coating

A mix of carbon and hydrogen, the ADLC coating (Amorphous Diamond Like Carbon) covers the components with a fine black protective layer unaffected by wear, self-lubricating, and highly shock-resistant. A technique used in aerospace and armament.

THE VACUUM-HOUSED WATCH

TO REDUCE AIR RESISTANCE, THE AUTOMOBILE WORLD’S ANSWER IS TO DESIGN SLEEK, AERODYNAMIC CARS. TO GET THE SAME RESULT IN THE WORLD OF WATCHMAKING, CARTIER DECIDED TO GET RID OF THE AIR INSIDE THE CASE OF ITS CONCEPT WATCH CARTIER ID TWO !

Inside a watch case a mind-boggling 75% of the energy is wasted through various friction and from air resistance. The case may be airtight but inside it each moving part, however small, undergoes aerodynamic pressure which dampens its movement. After examining the technical possibilities for improving the air penetration coefficients, the team at the Manufacture’s research and development laboratory had a brainwave: “What if, instead of trying to mitigate the consequences of aerodynamic pressure, we removed the cause ?” In other words : getting rid of the air ! Despite its apparent extreme simplicity, this revolutionary solution brought with it some equally extreme technical difficulties. To avoid the risk of leaks, the engineers had to design a case in just two parts, without any screws whatsoever. The seals between the case block and the back as well as those surrounding the setting crown have been made more airtight by the addition of nanoparticles. At the heart of Cartier ID Two, the movement beats freely inside a ceramic case whose perfect transparency reflects the absolute vacuum it houses. And in the absence of all aerodynamic resistance, it can develop considerably more energy than traditional watches.
