What is my Tudor worth?

[Second_Life]

Thanks for reading,

I have a 1975-1976 Tudor Prince Oysterdate Submariner, blue face with serial 799***.

Its been had to get an idea of value so looking for your ball park values.

I'm the original owner, no paperwork, been maintained, had water leak in 80s but had watch immediately serviced. Face shows water damage but slightly though noticable when inspected.

I went to a local pawn shop that only does jewelry and since the face has water damage they wouldn't even quote a value.
