Replacement of damaged, deeply scratched, or aged original crystals
Crystal refurbishment or repair projects
1. Is this a genuine Omega crystal?
No. It is a generic aftermarket replacement, not original, but matches the dimensions and AR coating of the listed Aqua Terra models.
2. Does this crystal fit other Aqua Terra sizes (e.g., 38mm or 41mm)?
The Aqua Terra line has multiple sizes (e.g., 34.6mm, 38mm, 38.5mm, 41mm). This crystal is specifically for 34.6mm. Measure your original crystal before ordering.
3. Will the blue AR coating peel off?
It will not peel under normal use. Avoid abrasion with hard objects or harsh cleaning. Fine scratches may appear over time – this is normal.
4. What should I pay attention to during installation?
Use a new sealing gasket, apply UV adhesive or crystal glue, and press evenly with a crystal press. Ensure the dome faces outward. Professional installation is recommended.
5. Will the original water resistance be maintained?
Aqua Terra models are typically 150m water resistant. Proper installation with a new gasket can restore similar resistance. A water resistance test is advised.
