the best 16710 is to get a one of the new 16570 that are superlumed, take the bezel and put a tw bezel on it, and a noob dial. i did a build before and it was super close. it will take a gen crystal and crown/tube. however, i sold it and went to a gen 1675. the worse part of the build was the super thick case. there is no substitute besides going gen the rep factory will NEVER replicate a thin case.
