The one you are looking at has several obvious "tells" that it is a replica. As dadog13 pointed out, the most obvious one is the cannon pin fix. If you hang around here long enough and look at enough PAM reps, it becomes the most obvious clue that the watch is a rep. If you simply don't care whether your watch is accurate and close to the genuine then go for it. If you do, look around here, read the Panerai forums posts on cannon pin fixes and superlumes and you'll see the difference.
