1. Is this a genuine Audemars Piguet crystal?
No. It is a generic aftermarket replacement, not original, but matches the dimensions and appearance of the listed references.
2. Will the original water resistance be maintained after installation?
Proper installation with a new gasket can restore everyday water resistance (typically 50m). A water resistance test is advised. (Gasket not included)
3. What should I pay attention to during installation?
Use a new gasket and UV adhesive, press evenly with a crystal press. Ensure no tilt. Professional installation is recommended.
4. 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.
5. Does this crystal fit 34mm Royal Oak references like 15450?
No. 34mm references typically use a larger crystal. Measure your original to confirm.
