This timepiece really delivers the whole package — convenient, one-push outdoor functionality in a watch that incorporates materials expected to help reduce environmental impact. Satisfy your passion for the great outdoors and love of the environment with the digital PRW-35.
The soft urethane band, designed with slits, delivers breathability and comfortable wear. Bio-based resins used in the band and key components in the case and case back keep the weight of the watch down and the comfort to your wrist up on those epic days you spend outdoors.
Simply push the large dedicated buttons along the right side of the case to check compass bearing, barometric pressure/altitude, and temperature. The mode name is shown near each button so you know at a glance which digital reading is displayed. The super-twisted nematic (STN) LCD and large, bold digital readout deliver excellent readability wherever you find yourself, even in the harshest terrains.
To this array of functions, add Casio performance with Tough Solar charging, Multiband 6 radio control, and water resistance up to 100 meters, and you are ready for action wherever you go.
