1. Is this a genuine IWC crown?
No. It is a generic aftermarket replacement, not original, but matches the listed references‘ dimensions.
2. Will the original water resistance be maintained after installation?
The crown contains a sealing gasket. Use a new gasket and silicone grease; proper installation can restore factory water resistance (typically 60m). A water resistance test is advised.
3. What should I pay attention to during installation?
Align the crown with the stem threads; avoid cross‑threading. Professional installation is recommended.
4. Does this crown fit other IWC pilot models like IW3777?
Different references may have different crown sizes. IW3777 typically uses a larger crown – do not mix. Measure your original to confirm.
5. Is the crown tube included?
Usually not. If a tube is needed, purchase separately. Confirm with the seller.
