After ruining two Panerai dials, I've gotten pretty good at luming. I use Scotch tape to delineate my longer straight edges to protect against overruns. I remove the tape immediately while the lume is still wet. If it starts drying, it leaves an irregular edge. I was bored, so I thought I'd post pics. Obviously, the lume doesn't glow this brightly. I overexposed the lume pic. The lume edges look slightly irregular in the photos but part of that is due to reflections. To the naked eye even at ultraclose inspection, it looks perfect. Excuse the dust on the crystal.
