I just heard about tritium luminescence and was curious.  The price was right so I bought it and it arrived in a couple of days.  I like it a lot.  I have to get up early and I can read this watch easily in total darkness.  It's nice and light and is easy to read the date and it has the military 24 hour numerals as well as the standard ones.  The white hands are easy to read in the daylight.  Just a nice clean watch.  I would recommend it.  I do wish the band was waterproof so I could wear it in the shower but it has leather components and I'm afraid it will ruin the band if I do so that's why only 4 stars.
