Wow never saw that before man, sorry to see such a beautiful watch suffering like that. Unfortunately I think it's either take a shot on EBay , but more than likely that's something Panerai is going to have to fix. I know how you feel about the money man,. I know when I started buying nice watches I didn't think about the costs of service if something went wrong or just routine servicing in general. I thought great I bought a beautiful watch!!! But the first time something went wrong and I got the estimate from Breitling I was sorely mistaken. These things are made to last forever but forever ain't cheap.
I hope it works out for you buddy , still a great watch .
