I was lucky and picked up a brand new 7750 of the bay for £130 and the gen date wheel was another £30 but deals like that don't come up very often. As far as I know the date font is the same on both the 17 and 25j movements.
I have a gen blue diver pro for my blue dialled franken. I have a gen croc on the way from the US and that will go on a rep deployment. I want a gen pro 1 and pro 2. Overall I prefer the pro 2 but the pro 1 is chunkier and looks real blingy on a black Arabic or stencil dialled SA.
I got a similar deal for an Eta 7750 on the bay. A Baume & Mercier. I am not sure I want to fit it in the upcoming SA... I have a feeling that we are in need of a V4/2012...
If you are putting in a gen dial then it's worth putting in the 7750 at the same time then selling the A7750 or keeping it as a spare if you have other 7750 based reps. Otherwise I'd run the Asian till it dies then put the Swiss in.
With your setup I'd put the dial and movement in the v2 and save the bezel or sell it on.
you've really been lucky with those 7750 guys. i didn't manage to get something that cheap yet. i couldn't get a good pic of the bezel on my v2 due to bad camera and worse photo skills. i'll try in daylight. generally it looks bang on compared to the gen. it would really require a loupe to call it out. I think if you're lucky enough with v2 to have a good b print on the bezel there is really nothing to worry about.
