The problem with QC being asked for is that our dealers here probably have the best QC in the industry. The issue for the most part is, that we as a small subset of buyers really have much higher expectations for QC than others as we know the differences between versions, variations, nuances etc of the watches. I don't think we're going to get better QC than what we have...because you are asking for somebody to examine under a loupe all the details over the right sized flying "B", correct clasp, lume dot filling, etc which I don't think will happen.
Nobody else has mentioned it so it might not be that big a priority, but my desires for the rep world, are more movement based:
