I've been lurking on the GP board for a while because I knew my grandfather has a GP he bought many years ago. He has been wearing the watch on a daily basis since he bought it new on February 22, 1975.
I am very happy as he has just given me this watch.
The warranty card says "Number of Watch: 8897-U" (or it could be a V at the end).
I'm curious on the movement inside, is it in-house?
Also, as can be seen from this photo, there's some damage on the outer edge of the face. Wonder if it's something that can easily be fixed?
Lastly, I think the watch might need a servicing. When winding, the crown makes a "clicking" sound once when starting to wind and it feels a bit "loose". I'm sorry, I don't know how to describe it better.
Thanks in advance for whatever info can be provided on this watch.
