TR853-1 has written a new 50Gs blog post on the red S-Kool G-5500C-4. This G-Shock model was released in 2007 in a set with two other colors. It has Tough Solar charging and all the standard functions found in the 3062 module, but it's matching red negative LCD is probably its most distinguishing feature. It's pretty tough to find one of these new nowadays, but follow the link over and you can get a good look at this watch.
