Take on the toughest terrain with the G-SHOCK MUDMASTER GWG2000-1A3, designed to handle the harshest, roughest on-land environments. This shock-resistant watch is constructed to withstand all the mud and sand your adventures may bring, and it leverages our latest exterior technology to deliver a smaller profile with an even better fit. This compact design is made possible by the forged carbon bezel, carbon core guard case structure, and mud-resist buttons combined with stainless steel pipes and silicone buffers. Finely powdered carbon fiber is kneaded into resin, then heat-pressed to mold a bezel that is more complex, yet even stronger than before. Triple sensor measurements keep you updated with direction, altitude, barometric pressure, and temperature readings. Large Arabic numeral indexes, extra-thick arrow-shaped hands, double LED lights, and sapphire glass ensure high visibility. The band is textured in the style of heavy-duty no-slip rubber grips, and the buttons are knurled for easy operation. A MUDMASTER designed for practicality, durability, and power.SPECIFICATIONS25 months on rechargeable battery (operation period when stored in total darkness with the power save function on after full charge) Size of case : 61.254.416.1mm Total weight : 106g Case / bezel material: Resin / Stainless steel Resin Band Neobrite Screw Lock Crown Carbon Core Guard structure Mud Resistant Multi-Band 6 Atomic Timekeeping Triple Sensor: Altimeter, Barometer/Thermometer, Digital Compass Countdown timer Measuring unit: 1 minute Countdown range: 60 minutes
