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.

Operation Guide

Compact, lightweight digital watches made with bio-based resins

Featuring a digital display that’s easy to read and use, even on a more compactly sized watch. Key resin components are made with eco-friendly bio-based resins. The lighter weight of these watches also supports your active and eco-conscious outdoor life. Ideal for camping, mountain-climbing, and everything in between.

FEATURE1

Lightweight and compact

The smaller case does not impede wrist movement and won’t get caught on your shirt cuff. The compact size also sits comfortably on slimmer wrists, too. The use of bio-based resins for the case-back also keeps the weight down, so you can wear this watch in comfort during long days spent enjoying the great outdoors.

FEATURE2

Expected to reduce environmental impact bio-based resins

The resin components of the case, case back, and band are made with bio-based resins produced using renewable organic resources such as castor oil plants and corn, helping to reduce the ecological footprint of these watches. Eco-consciousness rendered in physical form, a fitting material for a real outdoor tool.

FEATURE3

Large dedicated function buttons for one-push measurements

Get measurements of compass bearing, barometric pressure/temperature, and altitude with a single push of one of the three large dedicated function buttons. The non-slip knurled finish makes for more intuitive and accurate button operation, even when wearing gloves.

FEATURE4

Soft urethane band for a comfortable fit

The band is made with soft urethane for both strength and flexibility. Slits help shed perspiration for more comfortable wear, and a simple lever makes it easy to attach and remove — handy for cleaning and other maintenance. The PRW-35Y-3 features a rich blue-green band that recalls the forest.
