Replacement of damaged, deeply scratched, or aged original crystals
1. Is this a genuine Patek Philippe crystal?
No. It is a generic aftermarket replacement, not original, but matches the 5170J dimensions and includes a gasket.
2. Will the original 30m water resistance be maintained after installation?
Proper installation with the included new gasket can restore everyday splash resistance (30m). A water resistance test is advised.
3. What should I pay attention to during installation?
Clean the case groove, place the new gasket, then the crystal. Press evenly with a crystal press with the dome facing outward. Professional installation is recommended.
4. What material is the gasket made of?
Typically high-quality rubber or silicone, offering good elasticity and aging resistance.
5. Does this crystal fit other 5170 references like 5170G or 5170R?
Yes, the 5170G (white gold) and 5170R (rose gold) share the same case dimensions and crystal size.
