I feel for you. I have a 359 as well bought from Mayors Jewelers down the street in Miami. Knock on wood, so far no problems other than running a few seconds fast per day. I'm writing to say, after a call to my guy at Mayors, he says there's one in the Orlando area and they are an Official Panerai AD. I'm not sure where you are in Central Florida but if you're interested, I'll get the address for that AD and we can go from there. I realize you didn't buy it from Mayor's but I was told they could help out if you do have some issues after dealing with the previous store. Hopefully, everything will go great and all this will be for nothing.
If you care to pursue it further, drop me a line at Russ767 at hotmail dot com.
