...and you might get an inkling as to why the lume has gone berserk. It's marked for radium, not tritium. Not really a health hazard except for anyone working on the dial - they would need to take a few common sense precautions. You'd have to be careful about getting a replacement radium dial too, you might come up against import restrictions.

That said, I actually prefer the other version of the dial anyway. The text on the radium dial comes very close to fouling both the date window and a marker, on the dial on the left there is clearer separation.
