I've owned a "few" VCs but I've never seen one like this. Maybe one of our other members have. You may want to contact Alex of The Hour Lounge as he will know for sure.
I have not seen a lot but i do not recall any with those hands, or the framed border around the Vacheron Contantin name on the dial.
You weren't kidding when you said poor pictures.. Try to ask for more, if he declines simply walk away; Its not worth getting scammed over a few photos. From the photos those hands look a little out of place to be honest.
