Radium
If I I am correct the Atomic commission of the USA . Set rules on radium dials in the early 60s . Due to lots of watchmakers falling ill.

So what you see on early 1960s Rolex they changed from radium to tritium .

That is also the period when the underline or exclamtion dot on the 6 o clock position appeared on the dial . As a way to show they have been tested for radium .

I also believe that it was only for USA market Rolex.
.
Rolex passion report has a great write up on that .

Question:
If anyone would give you a bottle that contains radium, would you take it home?
Your Rolex 5508 is a great catch.
Did you measure the strength or just guessing. With a dial that has no pitting may not be the material you think. Let me know. Bill
Hi bill , a guess
But the combination of grey plot colors change of color in the hands ,olive green underground, and the bezel turning grey at the same rate I am pretty sure it is radium. If it would've due to moisture and oxidation I would turn mor chocolate brown and it ...
