  • Super-Full-Auto LED light
    If the ambient light fades, a turn of your wrist illuminates the watch display particularly brightly.
  • Low-temperature resistant (-10 °C)
    Even temperatures as low as -10 °C have no effect on this watch.
  • Solar Power
    A solar cell provides power for operation.
  • Radio signal reception (EU, USA, Japan, China)
    Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China – once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time.
  • Digital-compass
    A built-in direction sensor detecs the magnetic north.
  • Barometer (260 / 1.100 hPa)
    A special sensor measures the air pressure (measuring range: 260 / 1100 hPa) and presents this on the display in the form of a symbol. This enables early detection of weather trends.
  • 10,000 m Altimeter
    A pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10,000 m.
  • Height Gain
    The height gain sums all the meters you have climbed in a session, so that you can see at a glance the total ascent on a tour.
  • Altimeter data memory
    Depending on the model, up to 40 sets of elevation data can be stored in the watch’s data memory and re-accessed at any time. Each of these data sets consists of a measured altitude as well as the date and time. In addition to the individual altitudes, the maximum and minimum altitudes during a measurement are also stored.
  • Thermometer (-10°C / +60°C)
    A sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C).

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.

RADIO WATCH TECHNOLOGY.
The advantages of radio-controlled watches are obvious: Once they have been set to the relevant time zone, they always display the exact local time. All CASIO radio watches receive signals almost anywhere in Europe. Some models even receive signals in North America, parts of Canada and Mexico (the radio tower in Fort Collins sends signals for a radius of up to 3200 km) and even in Japan or China. In Europe, the change from summer to winter time is also completely automatic.

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.

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.
