Oh be still my beating heart!!
An expression to bring desire to any vintage Breitling lover - original 765 AVI.
You have a very fine watch sir, and you must immediately restore it to full working order
There's some information on these watches here -

In terms of value, well assuming that you have it serviced and bring it back to good condition then you are probably looking at something around $4,500 for a 1960s piece which is what I am assuming as you said that you have had it since 1965 - earlier ones are worth more - an early to mid 50s example sold for over $7,000 a few months ago.
