## Frequently Asked Questions
**1. Is this a genuine Rolex bezel gasket?**
No. It is a generic aftermarket replacement, not original, but fully compatible with the listed references.
**2. How do I know if the gasket needs replacement?**
If the bezel rotates too loosely, feels sticky, or if water or dust ingress is noticed under the bezel, the gasket has likely aged or failed.
**3. How do I install it?**
Place the gasket flat into the case groove without twisting, then press the bezel back on. Test for smooth rotation.
**4. How does nylon compare to rubber?**
Nylon has lower compression set and resists hardening over time, making it ideal for precision press‑fit applications. Rolex original bezel gaskets are also often nylon.
