Looks like tritium.. try to charge it with a torch in the dark and observe its behaviour, tritium would dim slowly after you put the light source away.
I did, the hands and pearl light up immediatly, but the undices are dead. 0 lume
Tritium on a 25+ years old Rolex is usually absolutely dead. Dial doesn't look like the lume is missing or stripped. The hands might have been replaced later in a service. How long do they glow?
That is strange indeed.
So it doesnt even light uo while the light is on?

Well that's not true.
You can find late 60's lume that still glow (due to multiple mix with zinc sulphide) if stimulated with UV for example, and in someway they even react also with sun light.
90's (and sometimes also very late 80's) lume may still glow a little in the dark after being exposed to light as it should glow under the UV light: 25 years old lume doesn't just stop glowing but it decreases slowly.
If you check it with a UV loupe you can still find some reaction in some examples.
