Experience the ultimate in durability and style. The GGB100 MUDMASTER model features a high rigidity carbon case that prevents damage and warping, ensuring extreme airtightness and shock resistance. The back cover is made of shock-resistant fine resin embedded with glass fibers, providing a high level of resistance to dust and mud. The bezel features three layers of fine resin with carbon fiber inserts and is accentuated in bright yellow, similar to that of rescue teams. It's also packed with features, including a digital compass, altimeter/barometer, thermometer, and step counter. Correcting time is easy with the dedicated G-SHOCK app, and you can access other useful functions such as the Mission Log that automatically records altitude data from the watch and route data from your smartphone. Get ready to take your timekeeping to new heights.
