I'm planning an Appalachian trail thru-hike and I'm trying to decide which watch to take. My top choices so far are the Casio Pathfinder PAG240, Suunto Core, and the Suunto Vector. I'm wanting something that will hold up considering that it will get wet, muddy, and possibly take a few bangs against rocks. I thought someone might have some suggestions. Maybe you know of another watch that would be better. I'm thinking I need an ABC watch. Are there any G-shocks with this capability? Thanks for any suggestions.
