This filament is called "Glow in the Dark" and seems to have been invented specifically for a dial.

And this is what the clock looks like during the day.
The front and the dial were separated, so you can simply clip on a different one when the old one gets too boring.

There was a small problem with the electronics: although the "right" driver was ordered, the "wrong" one (electronics with only one transistor) was delivered. With a little drilling, the circuit board was installed.
The clock runs perfectly, albeit with a small amplitude but without any lost or double ticks, using the original parts from the blueprint.
I'm very happy, thank you Steve for the wonderful construction!
Wow, that dial looks incredible. The rest of the clock also looks great.
What brand of glow in the dark filament did you use? I tried it once and it was rather bland looking. Yours looks amazing.
