A truly complete watch: practical outdoor features thanks to a single button; This watch is also made with environmentally friendly materials. Satisfy your passion for the outdoors and respect for the environment with the digital PRW-35. The soft urethane strap was designed by inserting slits, thus ensuring breathability and comfort. The bio-based resins used for the strap and the main components in the case and back guarantee a lightness on the wrist and plenty of comfort for your momentous days outdoors. Simply press the buttons along the right side of the case to control compass direction, barometric pressure/altitude, and temperature. The name of the function is visible next to each button, so you’ll immediately know what will appear digitally. The STN (Super-Twisted Nematic) LCD display and large, clearly visible digital display offer excellent readability wherever you are, even in the most challenging environments. To this range of features, add Casio performance with Tough Solar charging, Multiband 6 radio control and water resistance up to 10 bar and you’ll be ready for action, anywhere.
