Assorted Size Replacement Grooved Sapphire Crystal Compatible (No AR Coating)

Assorted Size Replacement Grooved Sapphire Crystal
Compatible with Rolex Models (No AR Coating)

This premium flat sapphire replacement crystal features a precisely machined center groove, engineered specifically to accommodate a waterproof compression gasket. Crafted from durable synthetic sapphire, it offers high scratch resistance and dial clarity — with no anti-reflective coating, preserving a natural high-gloss finish.

The centered groove is designed to hold a tension-style waterproof gasket, allowing for a secure press-fit installation directly into the bezel or case. This setup is commonly used in case builds inspired by classic diver and date watches, offering a reliable seal against water, dust, and impact.

Whether you’re restoring a vintage timepiece, performing a crystal upgrade, or building a custom mod, this crystal offers professional-level performance and precise compatibility.

Every crystal includes a free waterproof gasket to ensure a proper and secure fit right out of the box.
