It’s a practical solution for replacing a cracked, scratched, or yellowed original crystal while preserving the watch’s authentic appearance and performance.

Whether you’re refreshing an older timepiece or performing routine maintenance, this replacement crystal helps maintain both function and value.
Installation & Care
For best results, this sapphire crystal should be installed by a qualified watch technician using proper tools and techniques. The included Swiss nylon gasket must be correctly seated during installation to preserve the watch’s water resistance. While the crystal itself is highly durable and scratch-proof, care should still be taken during handling to avoid unnecessary pressure or impact. After installation, the watch can be worn confidently in everyday conditions, including exposure to water, thanks to the pressure-resistant gasket and secure fit. Regular cleaning with a soft, lint-free cloth will help maintain optical clarity over time.
