It looks real to me. The pearl is perfect, but that is not the only tell. It could be a franken with gen bezel insert and gen tube/crown, dial and hands and crystal. So the only real way to tell is the serial number and a pic of the back removed showing the movement. That would be the 100% tell is the movement. But I doubt you'd be able to get that from the seller. You could ask if you can have 3 days to inspect or money back and take it to a dealer to have them pull the case back. Just an idea.
