Nothing is immediately jumping out at me for concern. However, I'm not familiar enough with this model to give a highly confident opinion.
My true initial thoughts are: A Tourneau card isn't worth much to me. Have you tried inputting the serial into the Panerai 8 yr warranty extension to see if it's valid? Even if the warranty is out of date, it will still register if it's a legit serial.
If it was me, I would hold for a piece with full box + papers. This isn't a rare model and that shouldn't be too difficult to come by.
