I tried a search but there were so many posts covering everything about this new DOXA but two questions: Why is there an O-ring on the crown stem?; and why, with welded markers was Tritrium not tried? I still keep looking at every post I can and picture trying to see if and how this one might grow on me but it is a work in progress. Also not getting the original owner discount makes the price a bigger issue. The great thing is seeing so much of what was requested, actually ending up on the piece.
