About PRG-600 in Short. Representative of the tourist destination ProTrek with ana-digi display. Slim and compact body is the hallmark of the series. Due to the reduced dimensions, the PRG-600 has become a more attractive option not only for lovers of tourist walks, but also for ordinary people in urban areas. All the necessary information is displayed in a digital window at the bottom of the display – so the dial has become more minimalistic. The silicone strap is easy to remove – a special mount allows you to replace the strap in seconds. The case and display are resistant to frost [up to -20 ° C], and the solar battery removes the issue of replacing it every 2-3 years. The watch is equipped with a triple third-generation sensor – a barometer, thermometer and compass. The Japanese did not forget the basic features – a stopwatch, timer, alarm clock, world clock and calendar.

Feedback from users *accumulated information from our own comments and emails, forum threads, socials, reviews, etc.
+ full featured ABC functions and tough solar
+ easy to read and navigate
+ the coolest light up display at night
+ the numerals in the LCD window are positive
+ its a good one for an every day wear
– the crystal is flush with the bezel and not very well protected
– does leak a little in cold (at about 40 deg F or below) and tend to fog up inside
– the glass scratches easily
The most distinctive specs of PRG-600 *Editorial
— 100-meter water resistance (good for swimming but not for deep diving)
— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
— Low temperature resistant (stable operation of the watch is guaranteed even at a temperature of -20°C)
— Digital compass (measures and displays direction as one of 16 points)
— Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
— Barometer (measures the air pressures and displays tendencies in the weather)
— Altimeter (The electronic mechanism “estimates” the altitude based on the air pressure)
— Smart Access (the system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown)
— Dura-soft band (Despite the bands soft feel that made by silicon, it remains highly resistant to tearing and abrasion.)
— Moveable lugs (Moveable lugs connecting the band to the case assure a comfortable fit on the wrist)

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!
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.
Quick Access to Important Functions
With its electronic crown, the innovative Smart Access system provides intuitive access to key functions. By rotating and pressing the crown, the user can switch between individual features such as the altimeter or alarm, and settings can be adjusted quickly and directly. The Smart Access system is protected by a crown switch locking feature, preventing the watch from switching unintentionally to another mode.
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.
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.
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.
