PAM90 Power Reserve

[zbrock06]

I have a friend who just purchased a PAM90 Power Reserve (no box or papers). I opened the case back for him to find that it had the 7750-p3 OP III Movement. I am not familiar with Panerai, he said it was a pam90. I thought the PAM90 had the Caliber IX but this has the Panerai OPIII w. power reserve. It's a F series.

Is this possible?

I have attached the picture of the movement from the watch he purchased.


Here is a picture of the dial.
