Casio's Tough Solar Technology is the driving force behind the watch's ability to convert light into energy. This innovation is part of Casio's green initiative, which also features Eco-Friendly Biomass Construction and environmentally friendly/recyclable packaging, paperwork, and the user's manual. The Triple Sensor (Version 3) incorporated in this timepiece includes a Digital Compass, Barometer, Thermometer, and Altimeter, providing users with a comprehensive set of outdoor tools. With 100M Water Resistance, a Rotating Bezel, and a Super Illuminator with Full Auto LED/LCD Screen, this watch is built to withstand the demands of the great outdoors.

The measuring range extends from -700 to 10,000 m (-2,300 to 32,800 ft.), catering to the adventurous spirit. Originating from Japan, this watch is a testament to the manufacturer's commitment to craftsmanship and environmental consciousness.

The case, case back, and soft urethane band are all constructed with a material known as biomass plastics, a part of Casio's Bio-mass Plastics initiative. By utilizing renewable organic resources such as castor oil plants and corn, the brand aims to reduce its environmental footprint. This eco-friendly approach is a fitting choice for an outdoor tool that aims to bring the wearer in harmony with nature.

The Triple Sensor feature allows for direct access to measurements of direction, air pressure, temperature, and altitude, all accessible at the press of a single button. The oversized buttons are designed with a nonslip finish, ensuring effortless operation even when wearing gloves. Additionally, the improved sensor placement contributes to a slimmer profile on the side of the case.

Tough Solar Powered technology ensures long-lasting battery life, with an approximate operating time of 7 months on the rechargeable battery under normal use without exposure to light after a full charge. When stored in total darkness with the power save function on after a full charge, the battery can last up to 27 months.

Complementing the watch's rugged capabilities are features such as 100M Water Resistance, Low-temperature Resistance (-10°C), and a Tough Solar (solar-powered) system. The Triple Sensor suite includes a Digital Compass, Barometer, Altimeter, and Thermometer, providing a comprehensive set of outdoor tools. Additionally, the watch displays Sunrise and Sunset times, offers a 1/10-second Stopwatch (measuring capacity: 1,000 hours), a Countdown Timer, and 5 Daily Alarms, all enhanced by a Full-auto LED backlight (Super Illuminator).

The Duplex LCD design allows for the seamless integration of compass graphics on the top layer, while the bottom layer showcases the time and various measurements. This dual-layer construction has been engineered to minimize bulk, ensuring a slim profile.
