Casio's solar powered ProTrek Sports Watch PRG-600-1ER makes a great companion for trekkers as well as outdoor enthusiasts and explorers.
The watch has a number of practical features such as the World Time Function that keeps the time synched with a range of destinations, and the automatic LED face lighting as the watch is tilted towards you. You can set up to five separate alarms throughout the day to ensure you stay alert, while an auto calendar keeps track on the date.
A stopwatch allows you to keep time, with a countdown timer meaning you can create sessions on the go. But the best thing about the ProTrek is the Tough Solar power system, which allows the watch to charge the watch in low ambient lighting. This means it can be worn on expedition without the worry of your watch battery failing.
Navigation is also aided with a digital compass included to find north, an altimeter to measure height, a barometer to measure pressure, and a thermometer measures the temperature. It's a dynamic watch ready for adventure!
