Casio Releases New G-SHOCK RANGEMAN with Integrated GPS Navigation

February 28, 2018


28 February 2018 – CASIO has extended the G-SHOCK’s MASTER OF G collection with a new RANGEMAN model, the GPR-B1000. This addition to the family retains the successful formula of its predecessors, but comes enhanced with solar-powered GPS navigation capability – the first such function for a wristwatch in the world.

Like the rest of the MASTER OF G collection, the new RANGEMAN is built to thrive in demanding environments. Its oversized case has the familiar shock-resistant construction all G-SHOCKs come with, plus additional dust- and mud-resistant features to ensure its survival out in the field. The watch is also capable of functioning down to temperatures of -20 degrees Celsius. Within it is CASIO’S Triple Sensor, which measures compass bearing, atmospheric pressure/altitude, and temperature – vital information that contribute to the wearer’s situational awareness.

In a first for any G-SHOCK timepiece, the GPR-B1000 comes with standalone GPS navigation capabilities. The watch doesn’t just display the current location on a route or bearing to a location in real time, but also saves route and point data (including location, altitude, and temperature) throughout a track. By connecting the GPR-B1000 to a smartphone via Bluetooth, its wearer can download logged data from the watch and view it either as a map or a timeline. Routes can also be uploaded from the smartphone to the watch.

Powering the watch’s myriad functions is a battery that’s rechargeable via both wireless and solar charging systems. A 5-hour charge on the wireless system will power the GPR-B1000’s GPS functions for up to 33 hours, after which timekeeping functions will continue to be available. Solar charging supplements this out in the field, with GPS navigation extended by 1 hour for every 4 hours of charging under 50,000 lux conditions (equivalent to an overcast day in summer). To achieve this level of efficiency, CASIO refined its case construction to use a ceramic case back for the first time, to support both wireless charging and high-sensitivity GPS reception.
