I have just been given a 'genuine' Rolex Perpetual Date- Seamaster wrist watch. Well, that is what the man said. Whilst he had a lot of them under his old raincoat, he had an honest face!

So, he went and it stopped and I have got it going again, it is an automatic one. I now need to adjust the date etc. Can anyone tell me how to presumably unscrew the winder and which way to unscrew it to adjust it.

With such a valuable time piece, I am loathe to force anything!

Thanks in anticipation
