Cartier’s Crystal Ball: Inside the ID Two Concept Replica Watches

The ID Two’s most visually striking feature is its clear case, which is made from a material that is new to watchmaking. Cartier Replica Watches calls the material Ceramyst. It’s a polycrystalline ceramic consisting of magnesium, aluminum and oxygen. Unlike synthetic sapphire, Ceramyst can be molded – it does not require laborious machining and polishing. If you’re wondering whether the clear case is tough, Cartier says it’s the same material used for the bulletproof windows at the White House.

The case is manufactured in two parts: The Cartier Replica Watches US main case, including the lugs and crystal, are formed as a single unit. The second part is the caseback. Because the material can be molded, it can be formed into complex shapes.

The case material is extremely dense, and the two-part construction reduces the gasket length by 48 percent compared with a traditional design. These Cartier Replica Watches features facilitate another intriguing ID Two feature: a 99.8-percent vacuum inside the case.

To illustrate how the air inside a watch case affects the balance wheel, specifically, Cartier performed another of its science-class demonstrations. The results were surprising. A Calibre de Cartier Replica with 1904 caliber – minus the bracelet – was mounted on a stand, dial down. The balance wheel was tuned to oscillate at a lower-than-average amplitude of 140 degrees. A plastic hose ran from the watch case to an air pump.

The watch was also connected to a Witschi timing machine and to an air pressure gauge, and the Witschi timer and pressure gauge readings were displayed on a computer monitor, along with a video image of the balance wheel. Together, the various devices could pump the air out of the Best Cartier Replica Watches while displaying the air pressure inside the case and the effect on the balance wheel’s performance.
