What makes the upgrade little?
Honestly not sure on all the exact differences, but they are little for someone who wants a Panerai without nitpicking at the small differences compared to a gen. For someone who has pride in their collection and takes this hobby seriously, they would buy the Noob Fac.
Personally i bought the H-Fac, i think there is no difference in the movement being low and hi beat when there is only hour/minute hand. The H-Fac is also a 1:1 AFAIK, at least i one i bought was. The H-Fac also has its own differences that are closer to gen that the Noob doesn't have, and vice versa. There is a huge thread on this detailing the small differences. Personally, i couldn't see myself justifying that difference as it is 50% more of the price. I do this hobby for enjoyment, if i were to nitpick at all the small differences in gen for every rep i have, i could not be happy and could not enjoy this. Just buy the watch you know will be happy with, wear it and have fun.
