I had the VSF LN and now own the ZZF V3 Hulk and i still love more the ZZF because the quality, overall finishing and "gen" feeling is above to me !
The VSF has the perfect shape, crown guard, but finally feels more "cheap" than the ZZF...this is just the feeling i had once on the wrist .
I spent some time with the magnifier on the eye and i couldn't see a single flaw on the ZZF. The rehault engraving is very nicely done, the platinum coat on the bezel is perfectly applied, the bracelet sel is very sharp, etc... Do the same thing with the VSF and you will see that you are not at the same level of work !
I find also the brushing on the lugs and on the ZZ bracelet perfectly made, under the sunlight it's a true eyes pleasure.
The question is, what do you prefer ? ....a more accurate watch like the VSF, or a near perfect, a very high level of finish and quality ?
I think this is what you have to choose between the both watches, me i prefer the ZZF quality.
