I was excited to read that you got these from your Dad, but my heart sank a bit when I saw the photos. Both have major dial problems, which makes restoration more challenging. 🙁
The first one is badly damaged, and the second has apparently been repainted (note the gap between the "M" and "E" in Omega). So restoration would require dial refinishing in both cases. We can only know if it makes sense to make that investment if we can see the condition of the rest of the watches.
However, if they have major sentimental value, and money is not an issue, then I suspect they can be restored.
