Casio PROTREK PRW-2500

Casio introduces new PROTREK Watch for various environments including mountain and ocean. Displays Compass Bearing, Atmospheric Pressure/Altitude, and Temperature. In addition to displaying compass bearing, atmospheric pressure/altitude and temperature, the new PRW-2500 offers the enhanced performance and functions needed for use in water activities, such as 20 Bar water-resistance and a tide graph function.

The PROTREK series of outdoor watches make the most of Casio’s cutting-edge sensor technology to measure various kinds of natural data. Using separate sensors to gauge magnetism, pressure, and temperature, the triple-sensor models can display compass bearings, atmospheric pressure/altitude and temperature. This makes PROTREK watches very popular, not only among climbing enthusiasts, but also people who enjoy trekking and camping.

The new PRW-2500 is an all-round triple-sensor model that can be used in a wide range of settings including mountain, ocean and river environments. The watch not only offers the compass bearing and altitude features necessary for mountain climbing, but also strong water-resistance for river climbing and river rafting where the user may encounter strong water pressure, as well as convenient tide information for sea kayaking and fishing. It is even ideal for extreme adventure racing, which combines two or more endurance disciplines into a single outdoor race.

With a large display delivering outstanding readability, the PRW-2500 has a dual-layer LCD construction. The sensor and other data are shown on the upper and lower LCDs, allowing the user to easily see the desired information.

For the compass function, the upper LCD shows a graphic of the compass bearings, while the lower level displays the current time, bearing and bearing angle. For the tide function, the tide level graphic is displayed on the upper level, while the date, time, and moon phase and age are shown on the lower level. The vivid blue transparent graphic on the upper LCD still allows the graphics on the lower LCD to be seen underneath, maintaining good watch readability.

In addition to being displayed numerically and in a trend graph, atmospheric pressure is shown using simply designed arrow icons which depict characteristic barometric pressure patterns. This function was developed under the supervision of a meteorologist. Consequently, an upward arrow is displayed when the atmospheric pressure suddenly rises, forecasting better weather ahead. A downward arrow appears when the pressure suddenly falls, indicating weather deterioration. There are also arrow icons to show when rising pressure changes to falling pressure, or vice versa, making it easy to ascertain weather changes.

Naturally, the PRW-2500 can also measure altitude based on changes in atmospheric pressure. It not only displays the current altitude up to 10,000 meters, but also shows the current time and the recent change in altitude at the same time. This is handy for monitoring the pace of ascent up a mountain.

Among its strong basic features, the PRW-2500 employs radio-controlled technology for automatic time calibration using standard radio waves from six transmitters around the world. It also boasts the reliability of solar-powered time keeping. Finally, the watch’s basic shape and design make it easy to use as an essential tool, the softer resin watchband adds comfort, and the large compass bezel and buttons ensure good operation.
