About the watch

Part of the MASTER OF G series of watches designed for use in the most extreme conditions, the all new RANGEMAN challenges the limits of what a timepiece can be in true G-SHOCK style. Combining built in GPS Navigation with Bluetooth Low Energy technology and a Triple Sensor, this model is the pinnacle of outdoor practicality and desirability. All powered by a combination of Tough Solar power and/ or a ground breaking Wireless Charging system. A triumph of engineering, the GPW-B100 is built to the exacting standards expected from the G-SHOCK brand, resistant to shocks, freezing temperatures and deep water.

Collection tech

Mud Resistant

A cylindrical guard structure is adopted for all the buttons, and the cylindrical button shafts are fitted with gasket linings. This structure not only protects the buttons against intrusion by dust and mud, but it also helps to eliminate shocks. The crown is also protected by a highly airtight screw-lock structure. Gaskets are installed at points where the crown meets the surface of the case to assure superior resistance to dust and mud.

Vibration-Resistant

Alpha Gel is packed under and around the module to protect the watch from malfunctions or damage due to vibrations. Washers securing the lug screws help prevent vibrations from loosening the band.
