Its not a bad watch, at first I was disappointed that it didn't appear as bright as my phoso-illuminated watch, but when I compared them after about 30min in complete dark, the tritium won out and stayed mid bright all night as advertised. It isn't as bright as some expensive tritium watches out there, but it is a fraction of the cost. Drawbacks are that the second hand is standard phosphorescent material and diminishes after about 30min with no light exposure. Next drawback is that there are only phosphorescent dots for the 1,2,4,5,7,8,10,11 marks so you are making a judgment call in complete darkness as to where the hour hand and min hands are really pointing too. not a terribly big deal, you just don't get an EXACT point of reference with the limited tritium markers on this one. if you want to spend double plus the amount of money you can get the defender that has tritium markers on all numbers. Next drawback is the thickness is bulkier than it really needs to be, but you get used to that pretty quickly. The weight is light and you hardly notice you are wearing it. The movement keeps very accurate time, you may gain a few seconds a month 2-4. All my Casios ranged about 8-15 per month. If you want a Tritium watch this may be the ticket for a low budget purchase. Give it a couple of days and it will grow on you. Your going to be surprised how easy it is to read when you wake up at night to do your "business".

Addition on 8-8-11. Have had this for over a year now, no issues. remember to keep the movement screwed in to prevent water damage, it has a seal inside(o-ring) that is easy to forget about when adjusting your time.
