Friend of mine swears by them as a survival watch. Especially the underwater demolition model with is about 500 dollars... Any opinions on durability, design, functionality?

How about tritium being as bring as luminox stuff?

I have Omega SeaMaster I bought me self when I graduated but I will not use it in the field. It is my official tuxedo, suit, 007 night out watch that sits in my gun safe. Other watches that I have are source of my complains and those are Luminox navy seal and Marathon. I'm still looking for a perfect watch.
