Dead Rolex--need help!

[GregStevens]

Watch belongs to my neighbor. Long story short, it originally belonged to his father, Chuck "Black Bart" Bartholomew, who was a Navy underwater salvage expert--acutually led up the salvage mission for the first space shuttle disaster back in the 80's. Anyways, he died in a diving accident several years ago and his son inherited the watch and promptly went swimming with it while the crown was open. When he first noticed the moisture inside he took it to an AD but didn't want to spend the $500 or so to fix it. That was probably 15 years ago. Here's the deal. His wife wants to fix it up for him and give it to him for his 40th birthday as a surprise. So, my questions are:

1) Since the movement is pretty much dead--where can I pick up another 5512 or 5513 movement? How much do those go for? And,
2) Who can I trust to get the watch up and running again? I'm located in the US--California specifically. And,
3) What would be the estimated cost range for a project such as this?

We'd like to keep everything looking the way it looks now and just want it to work. Does that make sense? I personally think it looks great and has some history so I wouldn't want to lose any of that. Just get it running! Anyways, thanks for your help.
