This is a generic bezel gasket (O‑ring) designed for the Rolex Day-Date II reference 218235, made of durable nylon material. It sits between the rotating bezel and the case, providing a water‑tight seal and the correct friction for smooth bezel rotation. Replacing the original gasket when it becomes aged, hardened, or damaged restores bezel function and water resistance.
Nylon Material – Wear‑resistant, aging‑resistant, and corrosion‑resistant for long‑lasting sealing.
O‑Ring Design – Standard circular cross‑section for uniform sealing and damping.
Precise Dimensions – Specifically sized for the bezel construction of the 41mm Rolex Day-Date II 218235.
Restores Function – Replaces aged gaskets to eliminate bezel looseness or sticking, restoring smooth rotation.
Generic Aftermarket – Non‑original but fully compatible in size and performance.

Replacing aged or damaged bezel gaskets on the Rolex Day-Date II 218235.
Restoring water resistance and proper bezel rotation feel during service or maintenance.
Suitable for the 41mm Oyster case of the Day-Date II line.
1. Is this a genuine Rolex bezel gasket?
No. It is a generic aftermarket replacement, not original, but fully compatible with the 218235.
2. 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.
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. Should I replace other parts at the same time?
Inspect the bezel click spring and the ceramic insert adhesive ring; replace if worn.
5. Will the original water resistance be maintained after installation?
Yes, with proper installation and intact other seals, factory water resistance (typically 100m) can be restored. A water resistance test is recommended.
