This explains an ongoing mystery with my watch. I have a Submariner date with the tritium markings on the dial, and I always assumed it was just...you know...tritium. I always wondered why it would glow off and on even after the tritium died away since I know that tritium itself isn't phosphorescent.

Thanks for solving my mystery!
