The Casio Pro Trek PRW-61-1AJF is a high-performance outdoor watch designed for hikers, climbers, and nature enthusiasts. Part of the Pro Trek Climber Line, this model combines advanced sensor technology with environmentally conscious materials, delivering both functionality and sustainability.
This watch features Casio’s Triple Sensor technology, allowing users to measure direction, barometric pressure and altitude, as well as temperature with a single push of a button. These tools provide valuable environmental data for outdoor activities such as hiking, trekking, and mountaineering.
The PRW-61-1AJF is also designed with eco-friendly biomass plastics, derived from renewable organic resources. The case, band, and case back use plant-based materials such as castor oil and corn-derived components, reducing environmental impact while maintaining durability and comfort.
Powered by Casio’s Tough Solar charging system, the watch converts light into energy to keep the watch running without frequent battery changes. Multi-Band 6 radio reception automatically synchronizes the time using standard time signals from Japan, North America, the United Kingdom, Germany, and China.
The watch is built to withstand outdoor conditions with 100-meter water resistance and low-temperature resistance down to −10°C. A highly readable STN LCD display, bold bar indices, and dual LED lighting ensure excellent visibility in various environments.
With its advanced sensor capabilities, solar power technology, and eco-conscious design, the Pro Trek PRW-61-1AJF is a reliable companion for serious outdoor adventures.
