The World’s First*1 Solar-Assisted*2 GPS Navigation

*1 Based on a Casio survey as of January 9, 2018.
*2 Battery level drops below a usable level for GPS while outdoors, solar charging can be used to resume GPS functions for a limited time.

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.)

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.)

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.

Solar and Wireless Charging

GPS Antenna Bezel
The stainless-steel bezel incorporates a GPS antenna function. Stable reception is achieved by thus arranging the ring-form antenna outside the case.

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.

Bluetooth Smartphone Pairing to Connect with G-SHOCK Connected App

Navigation Route Setting
Register the start point, the destination and key points along the way on the map to create a GPS NAVI route map.

GPS Log Function
Save the trajectory of your movements on the app.
Review your route, altitude transitions and information on points along the way on a timeline display or 3D graphic display.

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.
