Casio Pro Trek PRW-30-1A

A digital PRW-30 model from the PRO TREK Climber line that can be intuitively operated. A large direct button that enables measurement of direction, barometric pressure/altitude, and temperature with a single press is positioned on the right side of the watch, while measurement results are displayed numerically in digital format. Next to each button, icons indicating direction, altitude, and barometric pressure are available, so functions can be recognized immediately, offering intuitive measurements and discernment of necessary information even in challenging outdoor environments. Furthermore, visibility has been improved through the use of STN liquid crystals and bold characters. In addition to measurement functions, the watch is equipped with basic performance functions, including Tough Solar, a radio wave reception function, and water resistance up to 10 bar: all of which make it suitable for even the toughest situations. And thanks to its more compact and lightweight design, the watch does not hinder wrist movements. Equipped with the durable Durasoft strap, it ensures greater wearability and can be worn for long periods during climbing and outdoors.
