Apparently your dial has somewhat reacted to moisture that entered between it and the glass at some stage. I would get it checked by a good watchmaker if any of that is still in the case and for waterproofness, although it shouldn't be the case as long as the watch is working fine!
I would also keep the tritium lume dial as it is, if that doesn't bother you, who knows, maybe they will find a name for it, something like "bubbleini" and your watch will soon sell at stratospheric prices!
A nice story by the way. Thanks for sharing it.
