## Product Description

This is a high‑quality generic replacement sapphire crystal for the Maurice Lacroix Masterpiece reference MP6388 (43mm case), measuring 34.6mm (diameter) × 3.8mm (overall height) × 1.8mm (edge thickness) with a domed round profile. 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**: 34.6mm diameter × 3.8mm overall height × 1.8mm edge thickness – designed for the Maurice Lacroix Masterpiece MP6388 43mm case.
- **Profile**: Domed round – raised center with thinner edges, offering a vintage domed appearance and enhanced dial protection.
- **Optical performance**: Often includes anti‑reflective coating (confirm with seller), reducing glare and improving dial readability, especially for complex dials.

## 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. Confirm with the seller before purchase.

**Q2: Will the watch retain its original 30m water resistance after replacement?**  
 A: Due to tolerances in generic parts, the original 30m rating cannot be guaranteed. Always perform a pressure test after installation. Treat as splash‑proof only.

**Q3: Is a gasket included with this crystal?**  
 A: No. Purchase a matching round gasket separately, and apply a thin layer of silicone grease before installation.
