1. Is this a genuine IWC crystal?
No. It is a generic aftermarket replacement, not original, but matches the IW5004 dimensions.
2. Will the original 60m water resistance be maintained after installation?
Proper installation with a new gasket can restore everyday water resistance (60m). 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, dome outward. Professional installation is recommended.
4. Does this crystal fit other Big Pilot models like IW5002?
The IW5002 also has a 46mm case and shares the same crystal dimensions. It should fit, but measure your original to confirm.
5. Is a gasket included?
Usually not. The sealing gasket must be purchased separately. Confirm with the seller.
