3-4 years ago, I posted a thread detailing my experience with a diy dial soldering station I put together from instructions in an old quartz watch repair guide. Unfortunately, the thread was 1 of those that got lost during 1 of the rwg upgrades, but, like I said, I was unsuccessful in securing feet without damaging the dial.
Try your luck with copper dial feet & epoxy or seek out an experienced watchmaker with the appropriate equipment (or find a dial/movement combo that matches).
