In general i agree with you better go clone, but noob and angus said that all diver's sold swiss will have a brand new swiss movement, i remember he even post pics of all the new movements for the diver over at RG in puretime threads..
After yes if you have a good watchsmith, you can always buy a gen eta yourself and ask him to install it in your diver... it depend on if you just want to receive the watch wear it and that's all or if you don't mind waiting a bit to install a swiss in it.. Like i said, i bought a clone, and if one day the movement dies on me, then i ll buy a gen eta low beat and ask my watchsmith until then the clone is good enough for me
