Replacement of aged, hardened, cracked, or deformed original crystal gaskets
Restoring water resistance during service or repair
1. Is this a genuine Patek Philippe gasket?
No. It is a generic aftermarket replacement, not original, but matches the dimensions of the listed Aquanaut models.
2. How do I choose the color?
Gold gaskets typically match rose or yellow gold cases; white gaskets match steel or white gold cases. Color does not affect function – choose based on preference.
3. What should I pay attention to during installation?
Clean the case groove and crystal edge. Place the gasket flat without twisting. Insert the crystal and press evenly. Professional installation is recommended.
4. How often should the gasket be replaced?
Rubber gaskets age over time. Replace every 2-3 years or whenever the crystal is removed during service. Replace immediately if hardened, cracked, or losing elasticity.
5. Will the original water resistance be maintained?
Aquanaut models are typically 120m water resistant. Proper installation with this gasket can restore similar resistance. A water resistance test is strongly advised.
