The Casio Pathfinder PAG40B-2V
Talk about the Casio Pathfinder PAG40B-2V. It's a very, very good watch if you're looking into buying something that you will use for a very long period of time. I've had mine since 2000, and I must say, aside from replacing the batteries every 2-3 years (depending on usage), it hasn't had anything repaired on it yet. Of course there are some minor scratches, but the triple sensor system is magnificent! It's almost like having a weather station attached to your wrist! The only thing you're missing with the Casio Pathfinder is a GPS feature.
