Rolex 1680 tritium

Recently looking at some old posts /articles mentioned that 1680made by tritium should be glow under uv exposure. Wondering if anyone heard this before or could share ur 1680 on hands to have a real uv light test ? Cheers

That is false,It will not glow.There will be tiny red and green specs that kind of glow under a 10x loupe.

Sorry that let me clarify the glow mean reaction under uv exposure. Ofcos this is not glow under normal dark environment. But I want to be confirm the reaction under uv . Since tritium has been used start around 60s late... some 5513 also used tritium but it had reaction under uv? How to explain this?

Under UV light, tritium looks green up to 1967 and possible 1968. It could possible glow for a few seconds once the light is shut off.

After 1967/68, the tritium will look white with a UV light and should not glow when the light is shut off.
