These subseries come with Compass
G-Shocks with compass can display the geographic orientation of the watch. Most models can also show the angle in degrees.
G-Shocks use a sensor made of two rectangular coils that detect slight tensions created by the earth's magnetic field. Depending on the position and direction, these tensions vary in intensity. There is a non-magnetic resistance between the two coils, which absorbs the subtle changes in tension. With each new position, the values that are measured by the resistance change. A microprocessor converts the measurements so that they can be displayed clearly on your watch.
