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.
5. Is a water resistance test required after installation?
Yes, a water resistance test is recommended to ensure factory‑spec performance (typically 100m).
