1. Is this a genuine Rolex crystal?
No. This is a generic aftermarket replacement crystal, not manufactured by Rolex, but built to the exact dimensions of the 116600 original.
2. Does the crystal include the Cyclops date magnifier?
Most generic 30.4mm crystals for the 116600 do include a Cyclops, but this varies by seller. Please confirm with the seller before purchasing whether the magnifier is present and its magnification level.
3. Will the original water resistance (1220m) be maintained after installation?
The crystal itself does not limit water resistance, but the final sealing depends on the gasket and installation quality. Always use a new, high-quality gasket and have a professional watchmaker pressure‑test the watch after installation (at least to 100m; for saturation diving, rigorous testing is required).
4. How can I be sure this crystal will fit my 116600?
Remove your original crystal and measure its diameter (should be 30.4mm) with a caliper. Also check for the Cyclops. If the dimensions match, this generic crystal will fit. Professional installation is strongly recommended.
5. Is a gasket included with the crystal?
Not always. Some sellers include a matching gasket, while others sell the crystal alone. A proper gasket is critical for water resistance. Please read the product description or contact the seller. We recommend purchasing a dedicated gasket for the Rolex 116600 separately if not included.
