Which Watch Should I Get?

I have about $350 and I want to buy a nice watch. I usually prefer the Dive watch or the hefty well build watch look. My original choices were between the Seiko Black Monster, Citizen Eco Drive, Luminox, Traser, Reactor Trident. Can I get some advice on which movement you prefer, which model you like out of those or another model you can think of, and the usual life expectancy the watch chosen. I also prefer the stainless steel or maratac watch bands over rubber. I really would like to get a Marathon Tsar but I'm not sure if I could spent $500 for a watch but if you look at it in the long run I'd have the watch for probably 20+ years. I'm just so confused :(
