I am not saying that he you are flaming DSN. I just simply said that if you read up more on DSNs watches before you bought, you would have known about the CG pin and lever and that you would have had to mod them yourself. These are not issues, and should be thrown out as problems. Same thing with the lume.
I would be a little upset about the brown strap when I clearly ordered black, but that would not be a huge concern to me either, as his straps would immediately come off anyway for a CBR or Tootall.
That crystal, however, is unexcusable. I would not have a watchsmith reseat it. Too much money for a crystal that is still either scratched or just plain bad. I would e-mail DSN and have him replace the watch for this. It will cost you a little extra to ship back to him, but will be cheaper than a new crystal and having it set. The crystal is just poor QC on DSN's part, but he will always make good on his mistakes, so you have nothing to worry about.
P.S. - the CG pin flattening and lever tightening are a piece of cake. Both can be done with basic household objects. Nice and easy.
