This is a generic bezel gasket (O‑ring) designed for the Rolex Yacht-Master 40 reference 126622, measuring 32.0 × 0.6 × 0.6 mm, made of nylon material. Installed between the rotating bezel and the case, this gasket provides a water‑tight seal and the correct rotational friction, ensuring smooth bezel operation and maintaining water resistance. This product is also compatible with the Yacht-Master 40 reference 126655, making it an ideal replacement for aged or damaged original gaskets.
Nylon Material – Wear‑resistant, aging‑resistant, and corrosion‑resistant for long‑lasting sealing.
O‑Ring Design – Standard circular cross‑section for uniform sealing and rotational friction.
Precise Dimensions – 32.0×0.6×0.6mm, specifically sized for the 40mm Yacht-Master bezel construction.
Multi‑Model Compatibility – Fits references 126622, 126655, and other 40mm Oyster case Yacht-Master models.
Restores Function – Replaces aged gaskets to eliminate bezel looseness or sticking, restoring smooth rotation and water resistance.

Suitable for the 40mm Oyster case Yacht-Master line.
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).
