About PRG-30 in Short. These are three new mid-size additions to the PRO TREK lineup of outdoor gear watches.
Maintaining Triple Sensor and Tough Solar functionality, the size and weight of these models have been reduced for better comfort during long-term wear.
The buttons for direct access to Triple Sensor measurements are located along the right side of the case, and a function name for each button is marked on the bezel for smooth, error-free operation.
The display uses a bolder font for improved legibility of both current time and other display information, even while the display is illuminated.

    Enjoy Japanese approaches to Travel and Functional ProTrek Watches!

    ProTrek Philosophy. Every adventure needs a reliable partner. PRO TREK is exactly the kind of watch that you need to meet the demands of your interests. PRO TREK is equipped with functions such as solar power operation, a digital compass, an altimeter, a barometer and a thermometer. The combination of innovative technology, a robust precision movement and state-of-the-art design makes the PRO TREK the perfect companion for all adventures under the open sky. Mountain or valley? Forest or meadow? River or lake? No matter what awaits you, you will be well-prepared to make any rough terrain your own thanks to the PRO TREK.
    Experience for yourself how PRO TREK opens up new horizons while always pointing you in the right direction!

    Triple Sensor. PRO TREK watches are equipped with the latest Triple Sensor, version 3 technology, making them even more accurate than before. Three highly sensitive, extremely small sensors measure with absolute precision and instantly display changes in your environment. The precision of the digital compass, altimeter, barometer and thermometer is only possible with the Triple Sensor technology. At the same time, the three layer sensor is 95% smaller and consumes 90% less energy than before.

    Tough Solar. The CASIO Tough Solar System is now so advanced that even the weakest light sources are sufficient to operate the watches. The solar cells are so small and inconspicuous that they can be integrated easily into every watch face design.
    An accumulator in solar watches saves “superfluous” energy and releases it when the watch is in darkness. The accumulator is charged automatically and does not require manual activation.

    Altimeter. For all those who set their sights high
    The built-in altimeter uses a pressure sensor to measure the current air pressure.
    The measured air pressure is then used to provide an “estimate” of the current altitude.
    The electronic mechanism in the watch is pre-programmed with “ISA values” (“International Standard Atmosphere”) used to convert pressure values into altitude values.
    The air pressure and temperature generally become lower as the altitude increases.
    These values define the connection between altitude, air pressure and temperature.


    Barometer. The barometer measures the air pressures and displays tendencies in the weather.
    The higher a person goes (ascent/terrain), the lower the barometric pressure will be.
    An increase in air pressure usually signifies an improvement in the weather.
    A decrease in air pressure usually means that bad weather is on its way.
    The air pressure is displayed with an accuracy of 1 hPa (hectopascals).
    The barometer can measure and display a range from 260 hPa to 1100 hPa.

    Digital Compass. The PRO TREK digital compass shows 16 compass points. The direction of magnetic north and the bearing are calculated by the compass’s directional sensor The directional sensor consists of two rectangular coils that detect slight tensions created by the earth’s magnetic field. Depending on the position and direction, these tensions vary in intensity. There is a non-magnetic resistance between the two coils, which absorbs the subtle changes in tension. With each new position, the values that are measured by the resistance change. A microprocessor converts the measurements so that they can be displayed clearly on your watch.

    Thermometer. The thermometer is used to measure the outside temperature.
    The temperature is displayed with an accuracy of 0.1 °C.
    The thermometer can measure and display a range from -10.0°C to 60.0°C.

    WATERTIGHTNESS. The watertightness of the CASIO watches complies with DIN 8310 and ISO 22810. These standards describe the various classes of watertightness and the test procedure used to determine watertightness.
    These standards apply to the general wristwatch usage. Watches with metre indications for watertightness cannot be used immediately in this water depth, however, as water resistance metre indications are merely a pictorial representation of the test pressure. A wristwatch withstands the impact of water at the static pressure specified on the watch (e.g. 10 bar) and the theoretical immersion in water to the specified depth.
