Breaking News! Time Traveller goes back in Time to attend Chaplin Premiere!

Since practical time travel would violate much of what we believe to be true about the fundamental rules of the universe the first question would be how would you convince me that a photo that seems to contain irrefutable evidence of time travel wasn't a fake.

And assuming they're trying to blend in, it would be hard to say what would be proof because anything to obvious as a digital watch you'd have to wonder how they could be so stupid to leave it so visible.

One thing that comes to mind as something more likely to slip notice would be a polio vaccination scar (though that would place the time traveler as from a very specific future time). But that probably wouldn't be clear enough in most photographs to be certain of what it was. In a validated audio recording I imagine the occasional anachronistic form of speech couldn't help but slip in.
