This is a generic sapphire crystal for the Omega Constellation 1202.10.00 (also fits 111.20.36.20), measuring 27.0mm in diameter, 2.6mm overall thickness, and 1.9mm step thickness, featuring a domed round profile with blue anti-reflective coating. The high-quality sapphire glass offers excellent scratch resistance, while the blue coating reduces glare and improves dial visibility, making it an ideal replacement for a damaged or scratched original crystal.

1. Is this a genuine Omega crystal?
No. This is a generic aftermarket replacement, not manufactured by Omega, but dimensionally identical to the Constellation 1202.10.00 crystal.
2. Which Omega models does this crystal fit?
It fits Constellation 1202.10.00 and 111.20.36.20. Other 27mm Constellation models may also fit, but always measure your original crystal dimensions before purchasing.
3. Will the blue coating peel off or affect readability?
The blue AR coating is durable under normal use but avoid hard abrasion. It reduces glare and improves readability; a slight blue tint at certain angles is normal and does not hinder clarity.
4. What should I pay attention to during installation?
This stepped crystal must be pressed into the case groove with a new sealing gasket and crystal adhesive (or UV glue). Professional installation is strongly recommended.
5. Will the original 50m water resistance be maintained after replacement?
Water resistance depends on the gasket and adhesive. With proper installation and a new gasket, everyday splash resistance (30-50m) can be restored. A pressure test is advised.
