I am thinking about building a 1680 with Phong case and dial, gen 1570 movement ... etc. I have modded a number of MBW 1680's, but have always been bothered by the small flaws that can't be corrected (or easily corrected); like crown placement, date wheel printing/alignment, etc. Before I dump a lot of money in this project, I would like to hear from those who have built these super Frankens. Is the end result more gen like or will I need to bite the bullet and start saving for a gen to be happy?
