Sorry for the bad photos..I can't get the back open and before I send it out I want to see if it's even worth doing.

The date changes by pulling/pushing the crown in and out, is that normal?

Model? Date? Any other info? Its running and keeping perfect time too!!

Thanks in advance!!

Date changing by pulling the crown : it's a caliber 565, that's normal.
