I found a a25363 Motor T on Craigslist for what seems like it must be a fake price ($600 talked down to $400). I haven't seen it yet but I told him it had to be fake or he'd never sell it that low but he swears its real and he has "the certificate with the Breitling seal on it embroiled out on the paper in Swiss along with the box and booklet." I have requested better pictures and I may go see it tomorrow out of curiosity sake, but I was wondering if you could help me out. I called my local jeweler and they said they cant authenticate watches. I read "There is only ONE open-heart Breitling. That is the Breitling for Bentley Mulliner Tourbillon. Chances are if someone is selling you one with a visible escapement, its fake." The one he is selling has an opening at the bottom, so does that end the discussion right there?
This first image I pulled from online so I dont even know if this one is fake or real, but its a lot clearer than the one he sent me so far.

The ones he sent so far:
The box also concerns me since it's not the usual Bentley box.



Thanks for the help.
