As I understand it, Rolex moved from Tritium to Superluminova sometime in the 90s. They use white C0 or C1 Superluminova. Though it glows all night expecially in the big round and trianglular indices... though it does glow all night, it glows weaker than most of the other SL colors. Of course C3 is the champ. iwc3

Maybe The Zigmeister and others have been doing this as well. I don't know, but I've been able to come up with a blend of Superluminova the resembles vintage tritium and vintage radium and yet glows almost as well as C3. I've been luming with superluminova for quite awhile. Its great stuff, but you can ruin a dial if you so much as blink at the wrong time. I posted some pictures of two original Tudor subs that have the vintage "Tritium" look and a 60s Certina that I relumed with the vintage "Radium" look. iwc3 If anyone is interested you can PM me. I have to tell you though, that I am pretty busy, and the turnaround time is about 4 weeks.
