Official Marketing Focus from Casio

By adopting a metal layer structure in which the watch body is sandwiched between metal bezels and a lug-integrated case back, the size fits perfectly at your fingertips. In addition, we have adopted a square side button with a special pattern that improves the feeling of holding the finger and a button guard that prevents malfunction of the button, achieving high operability in the field.
In addition to a triple sensor that can measure azimuth, altitude, pressure, and temperature, it is equipped with a tide graph that reads the ebb and flow of the tide and a fishing time function. It has a water resistant specification of 20 bar to cope with unexpected bad weather and various activities. In addition, the model has been finished to expand the range of activities in outdoor scenes such as mountains, rivers and the sea.
