The Pathfinder PAW1200T-7V features Casio’s revolutionary waveceptor atomic timekeeping technology and tough solar power, meaning no more worries of changing the time for daylight saving time or leap years. Atomic time is the official U.S. government time, the time that NASA uses when they’re counting down a shuttle launch and the time our military relies upon. The atomic transmitter conveys the time data as it is received, several times daily, through an antenna built right into the watch! The PAW1200T-7V is so much more than a timekeeping device. Incorporated into the new Pathfinder is a mass of features, including a digital compass, altimeter, barometer and thermometer. It’s every weather afficionado’s dream come true!
