Let me weigh in with a balanced opinion. What JohnC said above is pretty much dead on - hard core collectors want completely original pieces. Once original is gone, be it the paint on the dial or the factory edges on the case & lugs, you can't get it back again.
However, there's a flip side to this coin. The Genève you bought is a great watch to test out what you like. Wear it for a while and see if you like what's known as
wabi-sabi because you might enjoy it. If not, have a watchmaker who's sympathetic to vintage restore it without butchering the case so it retains a large percentage of it's original facets and crispness, but looks much newer. While that is one of the last nice Genèves made, it's not like it's an 18ct Constellation DeLuxe worth thousands so you have room to learn without killing a true collector's piece.
Many of us have an early Genève automatics. They make a great daily driver (i.e.: you wear it often under normal use) and are very attractive watches. I'd say it's one step past a starter vintage Omega. Somebody who knew a thing or two must have helped you vet that.
