This year sees CASIO upping its game as it introduces the most advanced multi-functional timepiece in its PRO TREK series for outdoor adventurers—the PRO TREK PRW-3500.
Initially released in February 2015, the Triple Sensor Version 3 delivers altitude, barometric pressure and direction readings that are more accurate than the previous models while boasting sensors that are 95 percent smaller.
