Me neither - but I assume it's correct / original to the watch, even if I didn't find any similar lume-style (also for other UGs) in Sala's book.
I should have taken a look in Salas book a bit more in depth than I did... Then I would have found sth. similar on page 255.
After reading I assume it's not lume but Sala calls it "small balls" / not "small balls made of ... gold" / "... tritium".
Those balls seem to look like the one on the posted watch - will post below for comparison.
Production time for both is within one year at around 1943+-
Still not sure what material it is.
Again for comparison:
