As for vintage panerai, my opinion is a matter of taste and personal preference.
I'm not sure if anyone who builds the 6514 homage wants to pretend that this is a gen of historical watches from the middle of the last century, for 100 + k $, one of the few units that have survived to our days.
For personal satisfaction with design and appearance, it can have any properties that interest its owner.
And yes, in most cases, this is a custom build. And this always prevents her from fully accepting another person. Buying stranger custom builds can match your taste in the unlikely event that it happens.
And finally, there are enough examples, valuable builds with no luminescent luminescence. In any case, it’s not radium, and not even tritium, so it’s hard to talk about the historical model. Just a vintage spirit, as close as possible to the details and personal preference of the builder / customer.
Just build what you like.
If you mean the PRE-V period, speaking of "vintage", then you don't have to worry, DSN shines no better than 30 year old tritium, like most well-known quality manufacturers.
If, as mentioned here, talking about the "call out" of your vintage pams, then I think there are not many people in the world who will take the responsibility to definitely say, guaranteeing with their reputation and means, whether, for example, any 3646 gen or not. This is a highly professional field, and what we try to do and wear with pleasure are just toys.
To summarize, the community knows what should and shouldn't glow.
Everyone makes a decision and does for himself. Do it for yourself, or go along with what others are suggesting for a fraction of the cost of building.
As for the usefulness of certain details, this is also a personal question, I am sure there will be a person who will say that it does not matter whether the dial is lit or not, if there is no gen SF240 inside to match the historical model, and this will also be a justified position. But personal.
