I'm looking for an outdoor watch for hikes (and my preps) and found The Casio G-Shock G9300-1 and the Pro Trek PRG-270-1. I've tried to read reviews, but couldn't find out if they are both solar atomic. What would be the main differences in terms of the solar cells and their longevity? It would be nice to have an ABC watch with the Pro Trek, but I'd like something built to last. Thank you!
