Casio Protrek PRG-300CM-4DR, Tough Solar Digital Men's Watch , Orange
Stay one step ahead of Mother Nature with the Solar Powered PRG-300CM-4DR with the module no. 3443, incorporating Casio’s new Triple Sensor Version 3 engine. Advanced CASIO original technology has allowed for a 95% smaller direction sensor and 90% reduction in sensor power consumption compared to previous models. Despite their smaller size, the new sensors in this model delivers better accuracy and energy efficiency. This model can measure Altitude in 1m increments (previously 5m) and display compass readings with 60-seconds of continuous measurement (previously 20 seconds). In addition to the altimeter and digital compass, the watch’s Barometer, incorporates a unique Barometric Pressure Tendency Alarm that alerts the wearer to sudden changes in pressure readings.
