I have a vintage Rolex but I am having a difficult time identifying it and wonder if anyone is willing to help me.It is not in the original case,therefore I do not have a serial # but it clearly says Rolex 15 jewels and there are also the letters FSAR on the back.I know nothing about watches other than that they tell time and was hoping someone might be willing to help me identify this watch.I can also take a photo and email it if required.
Thank you
