Casio Protrek Atomic PRW-3000-1JF Watch

The Casio Protrek is all about advanced measurements and it’s the miniature sensors to thank. They monitor every change in the surrounding and the measurements are remarkably accurate. So think it as an essential outdoor tool doubling up as a precision, fine-quality timepiece. PRO TREK measures directions, temperature and barometric pressure/altitude; even sudden changes. Hadn’t it been the 3-sensor technology, it would have taken another couple of decades for this 3rd generation wrist-wear to show up.
