Thanks for the input guys

I have ordered a HBB, I got my QC pics but the dealer rejected it a few minutes after sending the pics because he found a problem, so I am now waiting for QC pics of another watch.
Anyway, is there any way to see if the watch is an incorrectly called "V6.5" in other words mk2/v2 from the V6 maker?
I read the crystal is supposed to be higher on the "V6.5" version, is this true?
Again, this particular one has already been rejected by the dealer himself, I am just curious about the version, is it the latest V2 version (sometimes called "V6.5") from the V6-factory?
