Not the best photos, but from what I can see:
The case appears to have been polished. Not over-polished, perhaps, but it does degrade the value somewhat. Presumably it measures 36mm, which is a plus.
The dial has been discussed. And as for this:
No, very unlikely.
The movement appears to be in "good" condition. Some might argue "very good", but I prefer to be conservative, and cannot see all of the parts. I am unsure on the originality of the crown, but that is a relatively minor issue in any case.
In my view, if presented honestly, it is a ~$600-700 watch
at best. I say that partly because the current market is different than even a mere one or two years ago. The values of vintage watches without original dials, and/or not in excellent or better condition, have been falling. Collectors with money continue to buy really good examples of desirable watches, but the much larger "middle market", which was for years arguably inflated (along with many other markets), is now deflating fairly rapidly.
Anyone buying vintage watches these days who is concerned about near/mid-term value retention would be well-advised to emphasize both condition and originality. In other words, pay more for a really good, original example, unless you are comfortable wearing a watch with issues, and are not concerned about resale value.
