## Product Description
This is a high‑quality generic replacement sapphire crystal for the Omega Seamaster Planet Ocean 600M reference 232.30.42 (42mm case), measuring 30.5mm (diameter) × 4.1mm (overall height) × 3.3mm (edge thickness) with a domed profile and anti‑reflective (AR) coating. Made of synthetic sapphire glass (Mohs 9), it offers exceptional scratch resistance and excellent optical clarity, serving as a direct substitute for a damaged or scratched original crystal.
## Features & Function
- **Material**: Synthetic sapphire (Mohs 9), highly scratch-resistant, resistant to daily wear.
- **Precision dimensions**: 30.5mm diameter × 4.1mm overall height × 3.3mm edge thickness – designed for the Omega Seamaster Planet Ocean 232.30.42 (42mm case).
- **Profile**: Domed – thick edge (3.3mm) and large‑radius dome, providing excellent pressure resistance and a vintage diver aesthetic.
- **Optical performance**: Features anti‑reflective (AR) coating, reducing glare and enhancing dial legibility, especially underwater.
## FAQ
**Q1: How to tell if the crystal has an anti-reflective coating?**
A: Tilt the crystal under a light. A blue or purple reflection indicates AR coating; a white or pale yellow reflection means no coating. This product features AR coating.
**Q2: Will the watch retain its original 600m water resistance after replacement?**
A: Due to tolerances in generic parts, the original 600m rating cannot be guaranteed. Always perform a high‑pressure test (30 bar) after installation. For daily use, consider it 300m resistant; always retest before professional diving.
**Q3: Is a gasket included with this crystal?**
A: No. Purchase a matching round gasket (approx. 30.5mm ID, 0.8‑1.0mm cross‑section) separately, and apply a thin layer of silicone grease before installation.
