The ProTrek travel budget series with a triple sensor and digital display. The bezel in this model is aluminum – now the case not only looks more solid, but has become stronger. Advanced filling PRG-330 includes a barometer for measuring atmospheric pressure, a thermometer and a digital compass. Each of the listed functions has a separate quick launch button. The display and case are resistant to low temperatures – the manufacturer guarantees stable operation of the watch at -20 ° C. Thanks to solar power, you can forget about the periodic replacement of the battery. The basic functionality is represented by a stopwatch, timer, world clock and alarm clock.

- Full-Auto LED light
A twist of the wrist in weak light conditions automatically lights up the display backlight.
- 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.
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.
- Thermometer (-10°C / +60°C)
A sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C).
- 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.
