PRW-30Y-1B. Casio Protek. NWT. A digital model PRW-30 from the PRO TREK climber line that can be operated intuitively. A large direct button that enables measurement of direction, barometric pressure/altitude, and temperature with one push is placed on the right side of the watch, and the measurement results are digitally displayed numerically. Icons that indicate the direction, altitude, and barometric pressure are provided near each button so that functions can be recognized instantly. This enables intuitive measurement and grasp of necessary information even in harsh outdoor scenarios. Additionally, visibility has been improved by adopting an STN liquid crystal and bold font. In addition to the measurement functions, the watch is equipped with basic performance functions such as Tough Solar, a radio wave reception function, and 10 bar water resistance, so it can be used even in harsh scenarios. It has also been made smaller and lighter so as not to interfere with the movement of the wrist. It also uses a more durable Durasoft band. A stylish model that uses an inverted liquid crystal.
