I wanted a cheap, tough watch.  I work as a private security contractor and tritium was a benefit to me so that when I am doing surveillance I could check the time quickly one handed at a glance - without lighting up the interior of the vehicle or my face with a backlight (some indiglos are quite bright in pitch dark and any light is undesirable).  I don't care about alarms or hourly beeps - in fact, I don't want them.  This is simply a watch that tells time in the dark with a spinning bezel.  Just think of it as a cheap $30 watch (but tougher) that is illuminated by vials containing a glowing, chemical reactive gas.  The rotating bezel won't matter to most, but I use used it as an outdoorsman to practice dead reckoning navigation because you never know when you will need that skill.  I also understand that you can use this feature to very roughly calculate trajectory, but since I don't direct artillery strikes on anyone I'm not worried about that.
  This watch was great - the second time around.  The first one broke within two weeks of normal wear.  All of the hands simply fell off.  Literally, all of them.  I called Campco, the distributor, and they sent me a new one right away even before I could get the broken one in the mail.  The replacement worked under all sorts of abusive conditions as a nuclear security contractor and guardsman for two years.
  After two years the only trouble that I had out of it was after forgetting to screw down the knob after adjusting it during a trip to the beach, water logging it with sea water.  This was my fault.  The bezel started to turn hard and then eventually locked into place.  However, it still functioned for another year until it was lost.  So _ALWAYS_ screw down the knob after adjusting or it will not be waterproof!  If your bezel gives you trouble, take it to a jeweler right away to get a new seal.
  This thing got beaten, logged with ocean water, washed accidentally twice in complete cycles, made a 100 mile trip under my hood on top of my engine when I took it off to work on my truck and forgot about it, etc.  I am here to buy another one because my toddler nephews did something with my old one and I can't settle for a lesser watch now - and after the service it gave me I can't be bothered with paying $300 for a Luminox.  Three years of faithful service with lots of abuse.  And it is probably still ticking somewhere in a hidden crevice in my house.  No one is perfect and if you get a bad one Campco will treat you right with expediency.
  IMPORTANT! - _always_ make sure that you screw down the button after adjusting the time or date.
