I have the "Diver Professional" LUM with the camo face that I got for a real good price. The band was too big (because I think it was made to fit over a wetsuit) so I changed it out for one of their (overpriced) velcro & nylon straps. I've had it for a year or so and really like it. It's great for fishing - sturdy and heavy feeling, durable, waterproof and, most importantly, I can see it when I wake up at 4AM and thru until the sun rises. I don't know WHY I need to do that, but I like that I can.
My wife has one of the smaller "Navy Seal" ones (actually, I think the Seals tend to wear G-Shocks) and likes it because she can see it at night without her reading glasses.
I have one of the 'officer' ones which I like very much - dressy and I wear it to plays and concerts...that sort of thing.
I don't think they're worth the "list" price, but they're a good watch for the money if you get them on sale. For me, the specific purpose is to be able to clearly see the time at night - be it fishing, in a motel without a clock, or at a play/movie.
I got my fishing buddy an "Uzi" watch (which cost about 1/3) because it also has the tritium dial. Not as heavy or as 'solid' feeling, but he's taken it fishing with him for on to 7 months now and it takes a beating and does the job.
