CASIO G-SHOCK GPW-1000 is equipped with a low-power consumption, high-performance GPS LSI manufactured by Sony Corporation, which both companies collaborated on to customize for wristwatches. This enables the watch to achieve world-leading low power consumption. By combining Multi-Band 6 technology for receiving Radio Wave signals transmitted from six stations around the world with the GPS receiving function in a hybrid system, this new G-SHOCK can maintain accurate time more easily than ever before. The watch automatically receives standard time-calibration radio waves where available. When they are not available, the watch automatically receives GPS signals and adjusts the time, enabling the wearer to view the correct time at the current location.
