This is a tough one. The printing on the dial looks OK in the closeups, yet the fact that the star and the Ω are off troubles me.
The caseback issues also trouble me. That's not normal wear, as the medallion on that caseback is correctly recessed. To do that, either there was a manufacturing defect or someone went a little crazy with the polishing disc. I tend to think the latter, but anything is possible.
Movement is in very good condition, and I think that a 26M serial number is just right for a later cal. 564 model.
