Abstract
The "PROTREK" is the wrist watch series that CASIO has been producing for outdoor use which has advanced sensor technologies to measure various data. We proudly announce the newly developed analog wrist watch PROTREK PRX-7000T. This analog wrist watch is an atomic watch with solar powered and with three sensors to measure atmospheric pressure for altimeter and barometer, magnetic field for compass and temperature for thermometer. PRX-7000T is targeted to develop as a practical tool with the high visibility even at 8,000 meters altitude peaks in the Himalayan Mountains. This paper explains the technical summary of the development of PRX-7000T.
