Here is my 145.012-67 for comparison (direct sunlight vs. post-strong illumination test)
Such a clean dial, is it a relume? It looks very similar to the watch in question.
I might be being stupid, but if it's original lume and tritium has a half life of 12.5 years, should it still glow so strongly? Or did they not use tritium and instead something else?
EDIT: Or did it glow like that because of something you did to induce that... 馃槣

It isn't the tritium that glows. The tritium is purely the energy source to excite the phosphor luminescent paint. As long as this paint hasn't been damaged it can still be excited by another energy source.
Hi,
You are right, tritium has a very short half life. However, tritium was useful only to constantly irradiate the zinc phosphate which is the luminescent material.
The pictures provided were taken after a super strong light exposure and collected during 10-15 secondes revealing the glowing effect of the dial/hands combo.
By the way, you can see it on the third picture I provided (with my two Speedies visible) as the second hand is blurred as the collecting time was of about 10 seconds.
