Hi 60's Sub, this comparison side by side shows the difference, sorry mate, but that certainly is a re touched dial. The hands look as though they have been re lumed too. Still, since it was a gift from your grandfather you should cherish it, it's still an iconic piece and who knows, you might be able to find a good original period dial for it some day, they do appear from time to time. What serial no does it have and do you have any photo's of the movement.
