so I've recently found 4 vintage watches that belong to my grandfather, and they're all looking at a minimum of 30 years. As I'm a newbie when it comes to vintage watches, any help would be appreciated. First I have some general questions about vintage watches, for ex. do watch collectors (potential buyers) prefer the watch to be fixed when buying(new glass, cleaned mechanism from the inside, new strap etc) or do they prefer it to be in their original state with all the scratches marks that come with years? That being said, let me introduce you with the four watches (don't hesitate to give me an approximate price of the watches):
First one up is a Zenith, automatic in working condition with a gold electroplated bezel and original leather strap:

Next one is the Certina blue ribbon, also automatic and in working condition:
Third one is a Meister-Anker 22 jewels automatic, also in a working condition:
And the last one is a Helvetia automatic incabloc but in a non-working condition:
Thanks in advance for any advice and help provided!
