I've read some negative comments about LumiNox, but I needed a good watch and I'm glad I jumped. After a week of nearly constant use, it's comfortable, lightweight ( thanks to the carbon-fiber case ), and the nighttime illumination is superb! The gray face background is very stylish, not garish, which makes this watch good even for semi-formal outings -- if I ever go to one. The only thing I had a small problem with is the Evo rubber strap. I don't SCUBA anymore, and buckling that strap every morning was a bit of a hassle, so today I changed it to a tactical nylon strap from one of my failed watches. Much easier to work with. I obviously can't speak to long-term durability yet but since I don't dive and just use it for travel and night work I'll bet I get a good long use. A little more expensive than I had planned, but so far, I'm very satisfied.
