Casio G-Shock GPR-B1000 Watches

The largest and most massive jishoks to date are 60.3 × 57.7 × 20.2 mm. This watch represents the Rangeman range, which means it was created to survive in the harshest conditions. Dust and dirt-resistant housing, resistance to severe frosts and unsurpassed impact resistance – GPR-B1000 will become a reliable assistant in any situation. The strap is additionally reinforced with carbon inserts. A triple sensor [barometer / altimeter, thermometer and digital compass] will help you navigate in an unknown area and predict the weather, and the GPS navigation function will make it possible to track your route without using smartphones and other gadgets – a separate GPS receiver is installed here. For GPS navigation, a wireless charging function with a ceramic back cover and an uninterrupted operation reserve of up to 33 hours at maximum load is provided. The Bluetooth function allows you to connect to smartphones and intuitively configure all the functions of the watch. In navigation mode, you can keep a log of visited points on the ground – up to 60 records with information about the exact coordinates, time, altitude, air temperature, etc. A map of visited points is displayed directly on a new generation digital display with separate independent pixels. Sapphire crystal [not scratched], solar power, powerful backlighting and a basic set of features – the GPR-B1000 can be called the most “sophisticated” G-Shock-s at the moment.
