You say the crown was "bumped". It's hard to tell from your picture whether damage from a bump is obvious. If there is damage evident, the warranty may not apply, and you may have to pay to have it repaired. If the crown simply came apart, the warranty should cover it. Did you buy from an authorized dealer, and do you have a valid warranty? If it wasn't bought from an authorized dealer, you may be out of luck!
I was just sealing down the crown before going to the beach; Suddendly the crown bumped. Here there are more pictures...Do you think this a big problem? Seems just unscrewed.
Yeah; Just felt like unscrewed and when i tried to sealed again realized that the crown head can be removed easily
Bought from an AD with a warranty? Not a problem. Bought pre-owned, no paper or warranty? Problem! Bite the bullet, take it to an authorized repair facility and start the process. I very much doubt there is another option!
