It seems like the tritium dial on the Omega Speedmaster from the 90`s is fading, shrinking, and blemishes a lot faster than other tritium dials. I love the color and the way these dials look now, but will it be a problem further down the road. I am thinking dials where the tritium simply falls apart and off the watch?? Here is a pic from 1997 and one from 1977!!
