So I'm a little late to the party, but being a noob on the forums and seeing a thread that I could actually contribute to, I had to jump at the opportunity ... I've been a Combat Controller in the Air Force for almost 6 years now, and have had a few good "military" watches. My favorite and current is a Luminox, which is also a favorite of all those Squiddies in the Navy. I used a Casio forever and liked it just fine (I'll still even wear it most days when in civvies or training), but switched over to the Luminox after hearing great things about them, including how easy they are to read under water. They use small gas capsules rather than standard glow in the dark material, so they don't need light to charge, and are nice and bright without being too bright. The watch is accurate and durable, pretty resistant to scratching - great watch! Not familiar with their current lineup, but you could probably find a decent price online for a slightly older model.
I'm assuming those capsules contain tritium. What do you do when they go dim? Can they be replaced? The reason I ask is that I have some nite-sites on firearms and the tritium does decay over time.
