For the modern explorer, whose appreciation for the intricate mechanics of a fine timepiece is matched only by their reverence for the natural world, Casio presents a compelling proposition: the Pro Trek PRG-340B-3.

This is not merely a rugged outdoor companion; it is a testament to thoughtful engineering and a commitment to minimizing environmental impact, seamlessly blending robust functionality with a conscious approach to materials. The PRG-340B-3 stands as a sophisticated tool for those who venture off the beaten path, offering a suite of advanced features powered by sustainable technology.

At the heart of this Pro Trek lies a dedication to practicality and environmental responsibility. Key components, including the bezel, case, and case back, are crafted from bio-based resin, a material derived from renewable organic resources. This innovative approach not only contributes to a reduction in environmental footprint but also underscores Casio’s forward-thinking ethos.

This commitment to sustainability extends to the olive-green cloth band, fashioned from CASTLON®, a 100% plant-derived Nylon 11 fibre produced using castor oil plants. This carbon-neutral material boasts impressive strength, lightness, and enhanced resistance to wear, chemicals, and low temperatures, further demonstrating that performance and environmental consciousness can go hand in hand. Notably, the band is also treated with a flame-retardant finish, a thoughtful detail for those who embrace the campfire as part of their outdoor experience.

The Pro Trek PRG-340B-3 is a veritable command centre for the wilderness, equipped with Casio’s renowned Triple Sensor technology. This suite of sensors provides precise readings for compass bearing, barometric pressure, altitude, and temperature, essential data for navigating and understanding the surrounding environment. Powering these advanced features is Casio’s Tough Solar system, which harnesses the energy of the sun to keep the watch charged, ensuring reliable operation far from any power outlet. This self-sufficiency is a hallmark of the Pro Trek line, offering peace of mind to adventurers who venture into remote locales.

The watch face features a duplex LCD, a clever design element that enhances the readability of the digital compass. Compass graphics are displayed on the top layer, while the bottom layer provides a clear and concise presentation of the time and various measurements. This dual-layer construction is remarkably slim, minimizing bulk without compromising functionality.

Beyond its core sensor capabilities, the PRG-340B-3 offers a comprehensive array of features, including world time with 31 time zones, sunrise and sunset display, a 1/10-second stopwatch, a countdown timer, five daily alarms, and a full auto-calendar. A Super Illuminator LED backlight ensures excellent visibility in low-light conditions.

With an accuracy of ±15 seconds per month and a battery life of up to 27 months with the power-saving function engaged, the Casio Pro Trek PRG-340B-3 is a reliable and enduring companion for any outdoor pursuit. Priced at an accessible $260, this timepiece offers a compelling blend of advanced technology, sustainable materials, and rugged durability, making it an ideal choice for nature enthusiasts who appreciate both innovation and environmental responsibility in their gear.
