For decades, Casio’s ProTrek line has been synonymous with rugged outdoor capability, consistently pushing the boundaries of what a tool watch can do since its inception in 1995. With roots going back to the first watch with a GPS sensor and evolving through high-tech quad-sensors, ProTrek has spent three decades pursuing the ultimate in outdoor gear. The Casio ProTrek PRG-340 Recycle Band Watch represents the next evolutionary step in this storied lineage, showcasing ProTrek’s commitment not only to performance but also to reducing environmental impact through the use of sustainable materials, while remaining a formidable companion for life out of doors.


This robust timepiece, measuring 51.7mm in diameter (54.7mm length, 15.1mm thickness, 23mm lug width) with a mineral glass lens, features a resin case and silicone strap specifically created with recycled materials. The new Dura Soft strap’s unique finish is a direct visual result of this recycling process, adding a tactile dimension to its sustainable origins. This commitment to recycled materials is a key aspect of the PRG-340 series, reflecting a conscious effort towards environmental responsibility.


Functionality is where ProTrek truly shines, and the PRG-340 is packed with sensors designed for life out of doors. It features a thermometer, barometer, and altimeter – providing crucial environmental data at a glance – coupled with a digital compass to aid in navigation, ensuring you can find your way regardless of the conditions. All this vital information is clearly visible through the watch’s new dual-layer LCD display, which also includes a Sunrise/Sunset Display, adding another layer of outdoor utility.



Powering the Pro Trek PRG-340 series is Casio’s reliable Tough Solar 3513 module. This means the watch is powered by light, eliminating the need for regular battery changes and offering an environmentally friendly power source with a power reserve of approximately 7 months when fully charged. Beyond the core outdoor sensors, the module delivers a comprehensive digital experience for the outdoorsman, featuring World Time, a 1/100-second stopwatch, a 60-minute countdown timer, 5 daily alarms and an hour time signal, an LED light for visibility, and a full-auto calendar extending to 2099. With an accuracy of +/- 15 seconds per month, it keeps precise time even in challenging environments. The watch also boasts 100m of water resistance, ensuring it’s ready for unexpected rain or splashes encountered on the trail.



Rooted in Casio’s broader legacy of innovation since 1946 (from calculators to synthesisers and cameras, alongside famous watch lines like G-Shock and Edifice), the ProTrek line embodies a tech-forward approach. The ProTrek PRG-340 Recycle Band Watch is a compelling evolution, blending ProTrek’s renowned outdoor capability with a clear commitment to sustainability through recycled materials in its construction. Available at a price point of $280, it stands as a reliable, feature-packed tool watch for the modern adventurer who values both robust performance and a reduced environmental impact, proving that going green doesn’t mean sacrificing capability.
