Product Overview
This sapphire watch glass crystal is a precision-engineered replacement designed specifically for 34mm Tudor Prince and Oysterdate models, including the 74033, 75203, and 25-282C. Crafted from high-grade white sapphire, it offers exceptional durability and optical performance that surpasses standard mineral or acrylic alternatives. The material’s inherent hardness—second only to diamond on the Mohs scale—makes it highly resistant to scratches, ensuring the crystal remains clear and unblemished even after years of daily wear. Whether you’re a watch collector restoring a vintage Tudor timepiece or a professional technician performing a repair, this crystal delivers factory-level accuracy in both fit and function. Its 29.1mm diameter matches the original specifications, and the integrated 2.5X cyclops lens provides true-to-form date magnification, just like the original Rolex and Tudor designs. The included gasket ensures a secure, watertight seal, helping maintain the watch’s waterproof integrity after installation. This makes the crystal suitable not only for dry environments but also for light water exposure, provided proper installation is performed.





Key Features
- Premium White Sapphire Construction – Made from genuine white sapphire, this crystal offers superior scratch resistance and long-term clarity. Unlike cheaper alternatives that may cloud or degrade over time, sapphire maintains its brilliance and structural integrity, preserving the watch’s appearance for years.
- Authentic 2.5X Cyclops Magnification – The built-in cyclops lens provides 2.5X magnification, identical to the original Tudor and Rolex specifications. This ensures the date display is easy to read without visual distortion, maintaining the classic aesthetic and functionality of the watch.
- No Lens Effect – Many aftermarket crystals suffer from a “fishbowl” or warped appearance due to poor lens curvature. This sapphire crystal is precision-molded to eliminate such distortions, delivering clear, undistorted viewing with accurate depth perception and color fidelity.
- Included Gasket for Watertight Seal – A compatible gasket is included with every crystal to support proper sealing during installation. This helps preserve the watch’s original water resistance, protecting the movement from moisture, dust, and other contaminants.
- Broad Compatibility Across Tudor Models – Designed to fit a wide range of 34mm Tudor Prince Oysterdate watches, including models 74033, 75203, 25-282C, and many others in the 74000, 75000, 84000, and 91500 series. This versatility makes it a reliable choice for multiple restoration or repair projects.
