Due to the diversification of users’ tastes and preferences in recent years, we have already released the solar powered analog watch with the TripleSensor system as an outdoor watch. However, since further multifunctional demand has increased, we have developed a radio wave solar powered analog watch with multiple functions achieved by the development of a quad sensor system. This quad sensor system has a newly developed water depth sensor and the TripleSensor system with an improved digital compass achieved by an automatic horizontal correction function with an acceleration sensor.
