to all your questions, the previous version of the E series movement is a joke!! This is so much better but still not 100% gen like. I would rate the movement as 80%, but seriously I think they have done a great job in the movement.
As for the watch, the crystal has some distortions but so does the gen. I like the individual serial numbers on the new fiddys and also that the Cannon pin is perfect.
The case is really top notch!
For people who wants to franken a fiddy, for this watch, just pop in a gen movement and you are done!
It is good enough for me and I am not that easy to please, but this rep has really suprised me with its GEn like qualities.
