Among the well-dressed outdoor gear, Protrek’s triple sensor watches offered (equipped with mass solar charge system and wave ceptor,) a thin model with advanced fitting characteristics in June 2003.
PRW-1300J-1JF is still equipped with the multiband radio signal receiving function that corresponds with the five transmitting stations worldwide, and the solar-powered “Tough Solar,” When compared to the PRW-1100BJ, this watch was successfully downsized to 4.8mm(approx. 30%) x 5mm(approx. 10%) using thinner smaller electronic parts along with Casio’s original high-density packaging technology.
This thinner body dramatically improved its fitting character and reduced friction with outerwear. Improvements for outdoor gear have been achieved
Even when you wear gloves, you can operate the directional, barometric pressure, temperature and altitude measurement function by pushing a direct button, located in an independent position.
By full metal construction, it improved the quality of the material, toughness, and equipped with button guard on the back casing, which prevents operational failure.
It measures the direction, barometric pressure, temperature, and altitude. The newly developed compact pressure sensor and review of the temperature sensor’s position, improved the accuracy of the pressure sensor’s measurement.
The digital compass measures the direction by sensing geomagnetism
Equipped the barometer and thermometer to display the trend of barometric pressure
The relative altimeter that measures the altitude based on change in barometric pressure

Corresponds to 5 standard radio transmitting stations worldwide. Provides automatic time correction in 2 transmitting stations of Japan, North America, Europe region.
Casio's own high capacitance solar system charges power even under relatively weak fluorescent lighting This system functions stably in many devices that need large amounts of power
