I am looking for my second G. As much as I love my square, I want a rounder, larger watch. As funny as it may sound, I also want a snooze on the alarm (overslept a couple of times). I'm torn between the GD-350 and the GW7900-B. Both are stealthy, which is one of my criteria. Both also have larger buttons, which I like. I've heard concerning things about the solar battery on the GW7900 and I've heard that the lithium battery on the GD can last a long time. But - I like the looks of the 7900 slightly more.
