Afterglow: A 1967 Rolex Submariner Reference 5512 With Tritium/Zinc Sulfide Markers
I recall when I first found a Rolex Submariner 5512 with zinc sulfide on the dial. It led to a major discussion on an Internet forum about whether the dial had been re-lumed or not. Well, years later, we know a lot more; and one thing that is now certain is that the dial had not been re-lumed, but that it was an original zinc sulfide dial.
