## Product Description

This is a high‑quality generic replacement sapphire crystal for the Omega Constellation references 1202.10.00 and 111.20.36.20 (36mm case), measuring 27.0mm (diameter) × 2.6mm (overall height) × 1.9mm (edge thickness) with a domed round profile and a blue anti‑reflective (AR) coating. Made of synthetic sapphire glass (Mohs hardness 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**: 27.0mm diameter × 2.6mm overall height × 1.9mm edge thickness – designed for the 36mm case of Omega Constellation references 1202.10.00, 111.20.36.20, etc.
- **Profile**: Domed round – raised center with tapered edges, matching the classic curved appearance of the Constellation collection.
- **Optical feature**: Blue anti-reflective coating reduces glare while adding an elegant blue reflection, enhancing dial legibility and complementing blue hands/markers.

## FAQ

**Q1: What is the difference between blue AR coating and clear AR coating?**  
 A: Blue AR coating reduces glare while reflecting a subtle blue hue – a common feature of original Omega Constellation crystals. Clear AR coating only reduces glare without the blue tint.

**Q2: How to tell if the crystal has blue AR coating?**  
 A: Tilt the crystal under a light. A vivid blue reflection indicates blue AR coating; white or pale yellow reflection means no blue coating. This product features blue AR coating.

**Q3: Will the watch retain its original 30‑50m water resistance after replacement?**  
 A: Due to tolerances in generic parts, the original rating cannot be guaranteed. Always perform a pressure test after installation. Treat as splash‑proof only.

**Q4: Is a gasket included with this crystal?**  
 A: No. Purchase a matching round gasket (approx. 27.0mm ID, 0.8‑1.0mm cross‑section) separately, and apply a thin layer of silicone grease before installation.

Q2: How to tell if the crystal has blue AR coating? A: Tilt the crystal under a light. A vivid blue reflection indicates blue AR coating; white or pale yellow reflection means no blue coating. This product features blue AR coating. Q3: Will the watch retain its original 30\u201150m water resistance after replacement? A: Due to tolerances in generic parts, the original rating cannot be guaranteed. Always perform a pressure test after installation. Treat as splash\u2011proof only. Q4: Is a gasket included with this crystal? A: No. Purchase a matching round gasket (approx. 27.0mm ID, 0.8\u20111.0mm cross\u2011section) separately, and apply a thin layer of silicone grease before installation. Why Choose SOFLY Watch Parts?
