CASIO to Release New G-SHOCK RANGEMAN with the World's First Solar-Assisted GPS Navigation
Designed for the Ultimate in Survival Toughness;

Norderstedt, January 9, 2018 - CASIO announced today the release of the latest addition to its RANGEMAN series of watches, which support the wearer even in survival situations. The new GPR-B1000 features the world's first* solar-assisted GPS navigation and will be available in two models.
* Based on a CASIO survey as of January 9, 2018.

The RANGEMAN is part of the "Master of G" series of watches designed for use in the most extreme conditions. RANGEMAN watches incorporate Triple Sensor to measure compass bearing, atmospheric pressure/altitude, and temperature, based on the concept of "Survival Toughness."

In addition to Triple Sensor, the new GPR-B1000 is capable of GPS navigation – a first for a G-SHOCK watch. The watch collects location data from GPS satellites to display the current location on a route or bearing to a destination, in real-time. The watch also saves track and point data (including longitude/latitude, altitude, and temperature) in memory.

Using Bluetooth®, the watch pairs with a smartphone to connect with the G-SHOCK Connected app, allowing the user to create routes or manage log data in the app. Tracks and point data saved in memory are displayed on a 3D map or as a timeline. The watch also receives data from time servers to keep accurate time anywhere in the world.

The GPR-B1000 features dual wireless and solar charging systems. The GPS functions are usable for up to 33 hours on a wireless charge of about five hours. Even if the battery level drops below a usable level for GPS while outdoors, solar charging can be used to resume GPS functions for a limited time. The time display is kept powered at all times using solar charging, regardless of the status of GPS functions.

The GPR-B1000 delivers toughness in construction and materials, with a dust- and mud-resistant structure and carbon fiber insert band. Designed for the ultimate in survival toughness, the GPR-B1000 is the latest evolution of G-SHOCK.

Main Features of the GPR-B1000

GPS Navigation
  • Navigate and Log
    The watch collects location data from GPS satellites to display the current location on a route or bearing to a destination, in real-time. Turn on GPS navigation to automatically record tracks with either four-second or one-minute interval recording. (Save up to 20 tracks in memory.)
  • Backtrack
    The watch helps users navigate back to where they started, using track data to display the route back to the starting point and bearing.
  • Point Memory
    The user can save point data (including date/time, longitude/latitude, altitude, atmospheric pressure, and temperature) by just pushing a button. Set point icons to indicate the type of point. (Save up to 60 points.)

Bluetooth Smartphone Pairing to Connect with G-SHOCK Connected App
  • Receive data from time servers to keep accurate time anywhere in the world
    When paired with a smartphone, the watch receives data from time servers to keep accurate time anywhere in the world. Easily configure world time cities, alarms, and timers from the G-SHOCK Connected app.
  • Start/End Point, Route Setting
    Set the start/end points to use GPS to navigate to a destination and create routes.
  • Display Tracks on 2D or 3D Maps
    Display saved tracks on a 2D or 3D map in the G-SHOCK Connected app.
  • Timeline display of waypoint data
    Display saved waypoint data in a timeline. View photos taken with the smartphone while using GPS navigation, in the timeline.

Solar and Wireless Charging
The GPR-B1000 is equipped with dual wireless and solar charging systems to support activities in the outdoors. GPS navigation is usable for approximately 33 hours on a wireless charge of about five hours. If the battery becomes depleted, GPS functions can be resumed by charging the watch in bright light. (GPS functions are usable for one hour on a solar charge of approximately four hours in 50,000 lux conditions.) Regardless of the status of GPS functions, solar charging keeps the time display powered at all times.

Ceramic Case Back – A First for G-SHOCK
The watch uses a ceramic case back to support wireless charging and high-sensitivity GPS reception. The case back uses a 2.0 mm thick ceramic material, making the watch shock-resistant and waterproof down to 200 meters.

Tough Construction to Withstand Harsh Conditions
The watch is designed to withstand harsh conditions with dust- and dirt-proof, mud-resistant construction, low-temperature resistance down to -20°C (-4°F), a carbon fiber insert band, and sapphire crystal.
