This is a high-quality generic replacement sapphire crystal for the Rado Diastar reference 160.0381.3, measuring 28.3mm (length) × 23.5mm (width).

Material: Synthetic sapphire (Mohs 9), highly scratch-resistant.
Precision dimensions: 28.3mm × 23.5mm (non-round, likely oval or shield-shaped), designed for the distinctive Diastar 160.0381.3 case.
Profile: Non-round (oval or faceted shield) matching the original crystal contour.
Optical performance: Often includes anti-reflective coating (confirm with seller), reducing glare.
Q1: What is the thickness of this crystal? Why is it not provided?
A: Thickness is not listed. Sapphire crystals typically range from 0.8‑2.0mm. Measure your original crystal‘s thickness and confirm with the seller before ordering.
Q2: 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; white or pale yellow means no coating. Confirm with the seller.
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 water resistance test after installation. Treat as splash‑proof only.
Q4: Is a gasket included with this crystal?
A: No. Purchase a matching shaped rubber gasket separately, and apply a thin layer of silicone grease before installation.
