Casio G-Shock Aviation GPS Hybrid Gravity Master GPW1000-1A

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.

Two mutually complementary time correction systems are integrated in a hybrid system that provides easier, more reliable time-calibration signal reception by using GPS data to adjust the time, even in environments outside the range of terrestrial radio waves.

Global Positioning System + Multi Band 6 radio signal reception capability

GRAVITYMASTER is equipped both to receive time-calibration signals by radio wave from any of the six transmission stations worldwide for use in precision time correction and to receive transmissions of position and time data from GPS satellites. It integrates the applications of two types of timepiece — a radio-controlled watch capable of more reliable signal reception and a GPS watch with wider-area coverage —to ensure time-keeping accuracy beyond the limits of conventional watches.

Original GPS algorithm providing faster, more accurate positioning information

When it receives positioning data from a GPS satellite, the system employs high-resolution map data to determine the user’s current location more precisely. Application of a variable data analysis technique to group regions with the same Summer Time setting in the same time zone enables it to make quick, accurate time difference adjustments.

New evolutionary advances in time telling

When the watch receives transmissions from a GPS satellite, the second hand indicates the current time and appropriate city name, while the small hand in the 3 o’clock position displays the latitude at the current location. A next-generation solar-powered, radio-controlled watch with full functionality in any region or time zone, the new GPS HYBRID WAVE CEPTOR has evolved uniquely in terms of both time telling and data presentation.
