I've owned three Ecodrives, have never babied them, and years later they are all still running. Great. They've worked around the house, gone fly fishing in some big rivers, mountain biking, hiking, shooting, kayaking, all without a whimper. Citizen has come up with "Super Tough" models and have had the Royal Marine version out for awhile and I have to wonder how much more durable can these models be? How do the standard Ecodrives and these "tougher" models compare to the G-Shock and Luminox offerings? Whatcha all think?
