Among Casio’s new product releases presented to the press at Baselworld is a new, analog G-Shock watch that combines GPS information and radio wave signals. This marks the first time that Casio has incorporated GPS technology into a G-Shock watch. The watch, called the GPW1000, will be able to synchronize to GPS and smartphone devices and to check its own timekeeping accuracy against satellites and atomic timekeeping signals.
The watch has several technological updates. Casio collaborated with Sony to make a new integrated GPS circuit for the watch. According to Casio, this Sony-manufactured LSI (large-scale integration) chip consumes less power than other GPS devices, and is customized for wristwatch use. The GPW1000 has a new shape of solar cell as well.
The GPW1000 uses Casio’s Multi-Band 6 technology to receive radio signals from one of six atomic-timekeeping stations around the world. Two calibration stations are located in Japan and one each in China, North America, the U.K. and Germany. The G-Shock will calibrate itself by default when it receives a time signal from one of these stations. Where a signal is not available, the watch will instead calibrate by GPS signal. As a result, Casio claims that the watch will always have the correct time for a given location.
The watch also has Multi-Mission Drive, a proprietary Casio technology that allows each of the watch’s hands to perform multiple functions. The motors that serve the Multi-Mission Drive are 26 percent smaller than in earlier watches.
