Silinvar

Patek Philippe is the Geneva-based manufacturer that developed Silinvar, a patented material obtained by oxidation in a vacuum that causes molecular changes in the surface of pure silica components. One of the main advantages of the components resulting from this technology is due to the fact that they allow the compensation of thermal variations, an essential quality for the stable operation of the oscillator. Another important point: since it is not a surface layer, they are not changed over time due to their operations.
