Restoring crown operation and water resistance during service
1. Is this a genuine Omega crown?
No. It is a generic aftermarket replacement, not original, but matches the dimensions of 069SX42055.
2. How do I know if it fits my watch?
Measure your original crown diameter (5.0mm) and thread (M0.90), and check height compatibility. Consult a watchmaker.
3. Will the original water resistance be maintained after installation?
The crown includes a sealing gasket. Use a new gasket and silicone grease. Proper installation can restore everyday water resistance. A water resistance test is advised.
4. What should I pay attention to during installation?
Align the crown with the stem threads; avoid cross-threading. Professional installation is recommended.
5. Will the gold finish fade?
Electroplated gold resists fading under normal wear. Avoid chemicals or prolonged sweat exposure.
