Spiromax is a totally new type of balance spring made from Silinvar, a revolutionary material based on monocrystalline silicon obtained by a vacuum oxidation process that allows it to compensate for temperature variations. This patented silicon-based material is the result of research financed in partnership with the Swatch Group and Rolex. Patek Philippe produced the reference 5350 in a limited edition of 300 pieces in 2006.
