The new G-Shock Rangeman watch was first revealed at the 35th Anniversary event in New York City and is coming in April 2018. The updated edition of the iconic survival series launches with two models, the black GPR-B1000-1 and khaki GPR-B1000-1B.

The new Rangeman is the world’s first solar-assisted GPS navigation device and also has a Triple Sensor (alti/barometer, compass, thermometer) and Bluetooth connectivity. The watch has a low-temperature LCD display (-20°C, -4°F), sapphire crystal, and carbon fiber insert band for enhanced durability. It is water-resistant to 200 meters and like the original it is resistant to mud and dust.

The GPR-B1000 is the first G-Shock with the Navigation System feature. The watch can display the current location on a route or bearing to a destination in real-time. Tracking data can be saved automatically in intervals and point data (time/date, longitude/latitude, altitude, atmospheric pressure, and temperature) can be recorded with the push of a button. Up to 20 tracks and 60 points can be saved to the memory log. The Backtrack function allows the user navigate to the starting point, using track data to display the route and current bearing. New routes can be created and log data managed on a Bluetooth-connected smartphone with the G-Shock Connected app, with a 2D and 3D map display and timeline for tracking data. Photos taken with the phone while using GPS can be displayed in the timeline view.

A connected smartphone also allows the watch to sync with internet time servers, and time-syncing can also be done with GPS signals. Like the original, the new Rangeman has sunrise and sunset data and now also has a tide graph and moon data feature is used past its limit.

Another new feature is wireless charging with a USB-powered base station. On a full wireless charge of five hours, the watch can use GPS functions for about 33 hours. Four hours of solar charging in bright sunlight (50,000 lux) will provide about one hour of GPS use. A full charge combined with solar power can up the total usage time to 48 hours. Casio says that the solar charging keeps the time display powered at all times, regardless of the status of GPS functions. That sounds like the time display will remain working even if the GPS
