In 1983 Casio launched its first Casio G-Shock model and made it clear that watches can also be unbreakable.
They first experimented with a mud-resistant casing, then shock-proof. Later they implemented the thermometer so that the clock also indicated the temperature.
These watches were also designed for divers with a water resistance of up to 200m. Subsequently, the pressure sensor for changes in temperature and the measurement of depth and altitude were implemented in Casio
In 1998 they eliminated the need for battery change by including solar-powered charging. 4 years later, the watch already had radio frequency.
The straps have also improved since their inception, with unbreakable fabric.
Nowadays, in addition to all these functions, the Casio G-Shock also have multiband technology, with altimeter, barometer, temperature sensor, either for use on land or for divers or aviators. In addition, some models also allow you to connect the watch with the Smartphone via Bluetooth.
In short, Casio G-Shock watches are resistant, functional, ecological and designed for the modern man and woman.
