1. Is this a genuine Cartier crystal?
No. It is a generic aftermarket replacement, not original, but sized specifically for 18.9mm octagonal Cartier cases.
2. Which specific Cartier models does this fit?
It fits watches using an 18.9mm square domed crystal, such as some Santos Galbée (older versions) and certain Must de Cartier models. Measure your original crystal to confirm.
3. 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.
4. Will the original water resistance be maintained?
Water resistance depends on the gasket and adhesive. Proper installation with a new gasket can restore everyday splash resistance (typically 30m). A water resistance test is advised.
5. Is a gasket included?
Usually not. The sealing gasket must be purchased separately. Confirm with the seller.
