The G-Shock GPW1000 series is the first hybrid watch that receives both GPS and radio signals.
The first G-Shock was born in 1983 out of an engineer’s passion for creating an “unbreakable watch,” challenging the common notion of the wristwatch. Since then, the G-Shock has continued to evolve over time by incorporating advanced technology and capturing trends based on a platform of toughness, to offer features, performance, and design that surpass the imagination of its wearers.
The GPW1000 watch was developed to realise the ultimate in toughness through refinements in accuracy and durability drawing on Casio technology. The watch offers unsurpassed toughness combined with the world’s first hybrid time keeping system. From dense forest to desert dunes, in marine environments or surrounded by buildings or indoors, the GPW1000 keeps accurate time anywhere in the world by receiving GPS signals and radio wave time-calibration signals transmitted from six stations worldwide.
The watch uses ultra-small motors for the hand drive mechanism, to secure the space to mount the hybrid time keeping system. To compensate for increased power consumption, the G-Shock GPW1000 features a new low-power consumption, high-performance GPS LSI, as well as a new shape of solar cell with high-efficiency output. Other features include a ceramic GPS antenna and fine resin case for high-signal sensitivity and shock-resistance.
The Triple G Resist construction features a reinforced construction to resist shocks, centrifugal force, and vibrations. A high strength and durability carbon fiber insert band, and bezel with scratch-resistant DLC coating ensure a level of toughness to withstand the harshest of environments.
