Replacement of damaged, deeply scratched, or aged original crystals
Crystal replacement during repair or restoration projects
1. Is this a genuine Zenith crystal?
No. It is a generic aftermarket replacement, not original, but matches the 03.3100.3600 dimensions and pan shape, and includes a gasket.
2. Does this crystal fit other Chronomaster models (e.g., 03.3100.3600/21.M3100)?
All variants within the 03.3100.3600 reference share the same case and crystal size. Other Chronomaster models (e.g., 38mm or older 42mm) have different crystal sizes – do not mix.
3. What should I pay attention to during installation?
Clean the case groove, place the new gasket, then the crystal. Press evenly with a crystal press, ensuring the dome faces outward. Professional installation is recommended.
4. Will the original 100m water resistance be maintained?
The Chronomaster Sport is rated for 100m water resistance. Proper installation with the included new gasket can restore similar resistance. A water resistance test is strongly advised.
5. What material is the included gasket made of?
The gasket is typically high‑quality rubber or silicone, offering good elasticity and aging resistance. Confirm with the actual product.
