Casio PRO TREK PRG-340-1ER

Product Information
Overview
The Casio Pro Trek PRG-340 is an outdoor-oriented digital watch built for hiking and outdoor activities, featuring Tough Solar and sensors to help you navigate and follow the elevation profile. The duplex LCD screen provides a larger compass display for faster reading, and the rotating bezel makes it easy to mark direction. Bio-based materials in the case and band provide a more environmentally conscious choice without compromising on function.
Comfort
Despite its size, the PRG-340 is light on the wrist, weighing around 54g, and the soft urethane band provides a flexible fit that works well even during activity. The watch is adapted for outdoor use with low temperature resistance down to -10°C and has clear LED lighting for dark conditions. Power Saving and a battery indicator make it practical on longer trips.
Why choose Casio Pro Trek PRG-340
Choose the PRG-340 if you want a serious outdoor tool on your wrist. You get a digital compass with memory function, altimeter with logging, barometer with pressure trend and alarm, and a thermometer for quick readings in the field. There's also world time, sunrise/sunset, stopwatch, timer and multiple alarms. Tough Solar provides operation with light as an energy source and 10 ATM water resistance makes it ready for weather and water.
