This is a generic bezel gasket (O‑ring) designed for the Rolex Day-Date 36 reference 118235, measuring 32.3 × 0.6 × 0.6 mm, made of nylon material. Installed between the bezel and the case, this gasket provides a water‑tight seal and cushioning, ensuring a snug bezel fit and maintaining water resistance. Replacing the original gasket when it becomes aged, hardened, or damaged restores proper bezel seating and water sealing.
Nylon Material – Wear‑resistant, aging‑resistant, and corrosion‑resistant for long‑lasting sealing.
O‑Ring Design – Standard circular cross‑section for uniform sealing and cushioning.
Precise Dimensions – 32.3×0.6×0.6mm, specifically sized for the 36mm President case bezel construction.
Restores Function – Replaces aged gaskets to eliminate bezel looseness and restore water sealing.
Generic Aftermarket – Non‑original but fully compatible with the 118235.

Restoring water resistance and proper bezel seating during service or maintenance.

1. Is this a genuine Rolex bezel gasket?
No. It is a generic aftermarket replacement, not original, but fully compatible with the 118235.
2. How do I know if the gasket needs replacement?
If the bezel feels loose, shows gaps, 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. Check for a snug fit.
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).
