The PRO TREK series of outdoor watches leverages Casio’s cutting-edge sensor technology to measure different types of outdoor data. Flagship PRO TREK models are equipped with triple sensors that measure compass bearing, altitude/atmospheric pressure, and temperature. They have continued to evolve as Casio seeks to develop watches that offer ultimate utility in the outdoors
