10 years of the first Advanced Research
The principle is that for each new Silinvar® part developed (Silicon-based material), a new Patek Advanced Research timepiece is released, housing the new part and all the ones previously unveiled
First step: 2005
subir imagenAdvantages:
- No lubrication
- Less wear (maybe more yet on the anchor's side...)
- Lighter (less inertia=less impact on accuracy because of shocks, less energy needed)
Second step: 2006
They added to the previous escape wheel the Spiromax which is the flat hairspring element of the program, in the Patek 5350's 324 caliber (300 pieces).
sube fotosAdvantages:
- Better isochronism
- Amagnetic
- Temperature compensated
- Lighter=less damage issues
Third step: 2008
Finally, two years after the previous elements, three parts added together:

Final step (to date): 2011

The result in accuracy is significant when combining the four elements
