Pursuit of the Power and Functionality to Survive in Desolate Places Designed for use in the most extreme environments on earth, from jungles to deserts, these G-Shock models feature a mud-resistant structure that ensures reliable performance under harsh conditions by preventing intrusion by sand, mud or dust and a Twin Sensor, sensor function that accurately detects such vital survival information as directions and temperatures. It is the watch of choice for rangers and rescue crews who conduct missions under the harsh conditions.
Mud-Resistant Structure Mud Resist construction helps to ensure that nothing gets into the watch when down and dirty work takes you deep into the dirt and sludge. Multiple gaskets are used on the pipes that guide buttons and shafts which keeps mud out. These pipes not only act to protect buttons from impact, they also enhance button operation.
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 alleviate 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.
Mud-Resistant Screw-Lock Structure
The pipes guard against intrusion by mud and alleviate lateral shocks.
Gaskets installed inside the cylinders and button shafts increase their airtightness.
Air vents positioned in the base of the button shafts prevent button malfunctions due to changes in air pressure.
