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.
What Makes This Trend Stand Out
- Solar-powered Wearables
- Widespread incorporation of photovoltaic charging into wristwear and small devices enabling prolonged off-grid operation and reduced reliance on disposable batteries.
- Bio-based Materials in Accessories
- Use of plant-derived resins and Nylon 11 textiles creating durable, lower-carbon components that redefine sustainability expectations for rugged products.
- Integrated Environmental Sensing
- Miniaturized barometers, altimeters, thermometers and compasses combined into single consumer-grade devices offering richer contextual data for outdoor decision-making.
Sectors Adopting This
- Outdoor Gear
- Equipment portfolios that blend technical sensing, eco-conscious materials and self-powering systems to meet demand for high-performance, low-maintenance expedition kit.
- Consumer Electronics
- Wearable electronics shifting toward energy-autonomous architectures and multifunction sensor arrays that expand use cases beyond conventional smartwatches.
- Textile and Materials
- Material suppliers and fabricators exploring bio-derived fibers and flame-retardant treatments that balance safety, durability and reduced environmental impact.
