Point is- its not helpful when people post information thats not relevant or is misleading. Certain models of the 5513 and 1675 made around 1966-1967 still glow today and the uneven look of the lume is very similar to this time period as well.

I see nothing in these photos that would lead me to believe the watch is re-lumed. That being said, I would need more information to be certain. Like, what is the serial number?

Ahh okay, thanks for clarifying, I didn’t know that. From the previous threads on lume it was my impression that none of the Submariners from that period still held glow, when the light source was turned off, which was why I commented like I did with a reference to two other watches far younger than the OP.

Agreed, this is specialized info, so people shouldn't guess. In particular, a zinc sulfide dial should glow under UV excitation. Here is a photo of my 1966 and 1977 ref 5513 Subs side-by-side under UV excitation.

Very interesting but not sure to understand. Does it mean that the 1977 lume does not react at all under UV?

No real emission. Some types of UV light make the lime look whitish, and people sometimes confuse that with emission, IMO.

I asked this question because I recently had in hand a 1675 from 1978; the dial was really original, not "perfect", with a very nice vanilla patina. Under UV: nothing... Like if it was just a yellow painting...
And I heard that the tritium Rolex lume changed a lot according to the era, and that in end of 70's, 80's, it could be normal to see a lume like that.
This picture in this thread was another example.

So of course the question, for the 1675, was: how to determine if it is a relume or not.... !

By the way, I had the answer, for the 1675 down there. From a dial specialist. Probably the best relumer in the world today.
It is an original.
No UV glow, except a white back light, no post glow.
