Don't be fooled by the classic analog look of the Casio Pro Trek PRG550-1A1 Altimeter Watch; behind that pretty face lurks an altimeter, compass, barometer, thermometer, and full-featured watch. As rugged as it is feature-packed, this new member of the Triple Sensor family runs on Tough Solar Power technology that recharges every time you take it out into the light.
The solar-powered, triple-sensor Casio ProTrek PRG550-1A1CR multifunction watch sports easy-to-use features, including a digital compass, altimeter, barometer and thermometer. No batteries to replace! Efficient, large-capacity solar battery requires very little light to recharge and lasts up to 6 months without recharging. 3-hand analog face features an LCD window, bringing together classic timepiece looks with cutting-edge data display capabilities. Triple sensors measure compass bearing, altitude/atmospheric pressure and temperature. Depending on the function selected, the second hand can point to magnetic north and indicate changes in atmospheric pressure or altitude from a preselected location. LCD window displays numerical sensor information such as compass direction angle value, altitude, atmospheric pressure and temperature. Features include a countdown timer, 1/100 second stopwatch, time in 12- or 24-hr. format, world time with 29 time zones, 5 daily alarms and hourly chime. Full auto LED light activates with a quick flick of the wrist, allowing you to check data and take readings with ease. Tough Solar Power conserves energy, allowing the Casio ProTrek PRG550-1A1CR multifunction watch to power down when not exposed to light for a certain period of time. 100m (330 ft.) water resistance and a stainless-steel case help protect the watch; resin wrist band is comfortable and durable.
