Is franken-ing really necessary for VSF you guys think? If I could swap out the rehaut somehow, I think it might (and I really mean "might") be worthwhile, but other than the hands (which btw are fricken ridiculously expensive) I just don't see much added value for swapping other parts out to gen. DW may be too I guess... but VSF looks pretty close.
I am as interested as you are!
My 2 cents (based on the 3 Gen parts I have lol):
Xtal- First impression is perhaps the xtal is slightly better but definitely not worth the 300 odd quid (which doubles the cost of the watch!!!) in my very inexperienced opinion.
Hands- TBH, it’s super tough for me to tell any difference with the hands unless I am splitting hairs. Maybe the gens are slightly - but ever so slightly - more 3D. Again not worth doubling the cost for perhaps a 1% improvement!
DW - For me, the DW is probably something (only a if you were looking for differences, again) that some numbers, more than others are every so slightly different.
Going to take the Gen DW, Hands and Xtal off my ZZF and swap to the VSF only cos I have the parts. Will try take some before and after pics on the VSF, although caveat that I don’t have a macro lens. Will try do it next week if I get some time.
