    Which are brighter, Ball watches marked with "T25" or simply just "T"?

    I am comparing the Enineer III Marvelight To the Engineer M Marvelight, the Engineer III seems to have thicker tubes but I don't know about the different Tritium markings on the dial. Which is brighter?

    My understanding is that T25 is the standard T. T50 is much brighter.

    The "T" rating has nothing to do with how much Tritium is in each tube. It measures the total amount of Tritium radiation within the watch. In fact some countries outlaw T100 for example.

    So basically A T100 watch will be brighter than a T25 because it has more Tritium in it. Not because the tube itself is brighter than a same color tube found in a T25 watch.

    So why do some Ball watches specify "T25" but others are simply maked "T Swiss"?

    Ball's T rating is actually between 25 - 100 for the aggregate of all the tritium, GTLS, markers.

    So a watch with a T rating may come in at 30, not that much brighter than T25, or it may be closer to 100. Most of the time, watches with the T rating are closer to 100, and so quite a bit brighter than a T25 rated watch, as in the case of a Spacemaster X-Lume or Engineer II Dual Time.

    That makes sense, so chances are the Engineer M Marvelight would be a fair bit brighter than the Engineer III M Marvelight

    Tube size and height matters as well. The Marvelight has some of the largest tubes of all of the Ball models to date.

    Two of my Ball watches side by side for comparison. One is labeled as T25 and one is labeled as T. I'll leave it to you to decide which is which, or whether it really matters.
