The bio-based resins used for the strap and the main components of the case and back ensure light weight on the wrist and plenty of comfort for days spent outdoors. Just press the buttons on the right side of the case to control compass direction, barometric pressure/altitude and temperature. The function name is visible next to each button, so you know at a glance what will be displayed digitally. The STN (Super-Twisted Nematic) LCD and large digital display offer excellent readability anywhere, even in the harshest environments. Add to this range of features Casio performance with Tough Solar charging, Multiband 6 radio control and water resistance to 100 meters and you're ready for action, anywhere.
