Nice article, G Shocks are popular with the Army. I didn't care for them, 3 out of 4 broke on me, so I stopped buying them. I was a firefighter in the Army, so maybe I was just harder on them.
I preferred Reactor, nicely priced and tough as nails. A cheap way to have a tube watch.
I had a couple of Invicta divers that were not even water resistant to rain, so I could never recommend them to someone in the military.
I also used a Deep Blue original 1000m watch and it did extremely well for me. I am not sure if I would trust the new Deep Blues, the new ones just don't seem as good as when they first came out.
I went with Reactor and Deep Blue because they were solid, tough and cheap. Those are the ones I found I could count on.
Several friends had Lume Tec and swore by them. I can't recall a Lume Tec needing replaced.
It's easier to fool people than to convince them that they have been fooled.
