First off I'd just like to know what they phosphorescent material on most Luminors is. Its been hard to google, so maybe its a trade secret?
I'd also like to know how the patina is simulated on the "dirty dials". I'd imagine its replicating an older (and probably more radioactive) natural patina of the watches of the 1950s. I just wonder what it is (now) as well as what its replicating. Perhaps its literally just a tinted layer with high reflectiveness but also high transmittance to allow the Luminor to shine through easily in lower light. E.g. its not a patina at all, which to my understanding is an oxide, or at least an oxygen reaction.
Nerdy question.... any ideas?
