The Casio PRO TREK PRG-340B-3 timepiece is an adventure-ready accessory engineered to help maximize wearer capabilities without losing sight of rugged style. The watch boasts a durable construction outfitted with tachymeter scales, stopwatch timing and textured bezels with metallic accents to give it an outdoor-ready profile. The accessory is solar-powered to eliminate the need for battery replacements or manual charging to simply take advantage of sunlight for power.

The Casio PRO TREK PRG-340B-3 timepiece also covers barometric pressure with altitude readings, temperature, compass and more. The watch has a bio-based resin base with a CASTLON cloth band that's 100% plant-derived Nylon 11fiber treated with a flame retardant. The olive green color scheme of the watch further drives home it naturalistic ethos.
