Replacement of damaged, deeply scratched, or aged/yellowed original crystals
Crystal repair or case refurbishment projects
1. Is this a genuine Tudor crystal?
No. It is a generic aftermarket replacement, not original, but dimensionally and visually matched to the listed Black Bay references.
2. Does this crystal fit other Black Bay models like 79230?
No. Non‑chronograph Black Bay models (e.g., 79230) use a different crystal size (approx. 32.5mm). Check your original crystal dimensions.
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?
Black Bay watches are typically 200m water resistant. Proper installation with a new gasket can restore similar resistance. A water resistance test is advised.
5. Is a gasket included?
Usually not. The sealing gasket must be purchased separately. Confirm with the seller.
