How did you see mainly that it was a V2 he sent and not a V1?
I just received my QC pictures of VSF V2 (10 days after I placed order) and I'm even not sure if it's a VSF or a MKF looking at the pictures

What is sure is that they put the wrong back case on it : it's backcase of a satndard 300m, there's no reference of SPECTRE or 007 on it at all... So I fell I'm gonna have to wait few more days to have this fixed :/
When it arrived I had no idea that there was a V2 that had been recently released.
But when i looked at it I thought the strap looked different from what i had seen in dealer pics.
The cut of the metal strap is flatter on the top and the angles are all cut on the underside.
Also the pics my dealer showed of the V1 there was a 'TM' etched on the clasp after the 007. (dont know if this was on all V1's but on his pics it was clearly there)
That is what made start looking at other dealers sites to see if i had been sent something else.
Ultimately that is where i discovered the V2 being listed.
How to tell it is VSF?
The movement i guess... Only VSF make the clone... all the others are decorated
Look for oversized balance wheel.... If its a decorated 2824 the balance wheel will be the same size as a normal 2824(smaller), it is very noticable.
Also Decorated movements will not have the regulator arm on the balance bridge, only the stud arm. The regulator will be hidden under the decoration to make it look more like the Omega.
The VSF clone will have the regulator arm and stud arm in plain sight.. (its the biggest 'tell' that it is not an Omega).
If your has none of the markings on the back that the Spectre should have then it must be something else he is showing you.
Hope you get it resolved
