    Ceramic case: robustness and luminosity
    This is the first time Greubel Forsey has demonstrated the movement inside a ceramic case. The manufacture of this case requires extremely high precision. The material is compacted by pressing and then shaped before firing. During the heat treatment, the material shrinks it by about 25%. Once the element is sintered at a very high temperature, the ceramic will solidify, making the watch case very hard and therefore more difficult to use. The material becomes very resistant to scratches and corrosion, which means that surface treatment requires excellent expertise. From polishing to linear or circular satin polishing, the surface treatment can perfect the outline of the timepiece, perfected with the true Greubel Forsey spirit. The dark blue ceramic brings a subtle flash to the Double Tourbillon 30 ° technology, while its physical properties make it extremely resistant.replica richard mille sapphire watches
