Key Features
- White Sapphire Construction – Manufactured from high-grade white sapphire, this crystal offers outstanding clarity and structural strength. Its material properties closely mirror the premium feel and visual quality of original Rolex components, providing a factory-consistent appearance and performance.
- Scratch Resistant Surface – The sapphire surface is highly resistant to scratches from everyday contact with hard objects such as keys, phone screens, and metal surfaces. This ensures the crystal remains clear and unmarked, preserving the legibility and elegance of the dial over extended use.
- 2.5x Cyclops Magnification – Integrated directly into the crystal, the Cyclops lens delivers 2.5x magnification over the date window, matching the functionality of the original Rolex design. This enhancement improves date readability without compromising the overall balance of the watch face.
- No Lens Distortion – Precision-machined to exacting tolerances, the crystal eliminates visual distortion across the entire viewing area. Whether viewed straight on or at an angle, the dial remains clear and undistorted, ensuring accurate time reading in all conditions.
- Included Nylon Gasket – The package includes a pressure-resistant nylon gasket designed to create a tight seal during installation. This component is essential for maintaining water resistance and protecting the internal movement from dust and moisture.
