The Casio G-Shock MTG tough solar atomic watch is near bulletproof, and a technological marvel. All for a very small price. I started collecting G-Shocks in 1987 when I worked outdoors using chain-saws, and I needed a tough, accurate watch. My first purchase was waiting 15 miles from where I was dropped off and I forded a stream and got hit by a car to get it. This Casio MTG is my fifth G-Shock, and I swear by them. I've had the MTG for three years and it does a fine job keeping track of my medications, with four timers and a stop watch. It's like something out of science fiction. The only problem I've had is the buttons, two of them breaking off because I pushed too hard and used the stopwatch heavily, a problem corrected by using a pen. But I'm getting a sixth Casio G-Shock, a newer MTG tough solar atomic watch, for Christmas. Because you can't have too many around.
