Casio Pro Trek PRW-6900

The PRW-6900 uses Casio's Triple Sensor system for a digital compass, barometric pressure and altitude, and temperature readings. It is designed for outdoor activities such as hiking and trekking.

It has stopwatch and timer functions, but it is not a racing chronograph in the same sense as a metal Edifice watch. Its main purpose is combining timekeeping with outdoor sensor data.

Yes. Its barometer can track pressure changes and provide a pressure-tendency alert, which may warn of a rapid shift in weather conditions. Such readings are useful clues, but hikers should still use a forecast and observe local conditions.

The PRW-6900 uses Tough Solar charging and Multi-Band 6 radio-controlled timekeeping on supported versions. Radio synchronization depends on regional transmitter coverage, while solar charging depends on regular exposure to light.
