I'm not a big G shock expert, but I admire the watches for their toughness and functionality. I'm thinking about adding one of the GW3000s to my collection because I like the look of them, but I'm curious on what you have to do to reference a 2nd timezone. I use GMT a lot at work, an I like being able to see two time zones relatively quickly. I looked a the GW-3000 manual, but without the watch in front of me it was a little tough to figure out. Thanks!
