Experience extreme adventures with the GWG-B1000 from the G-SHOCK Mudmaster series.
Designed to resist even the most difficult situations, this Master of G is particularly resistant to impacts, dust and mud thanks to the seal system and the completely redesigned protection structure which integrates components made of different materials: for the exterior in metal High-precision forging techniques are used, while the case is made of resin reinforced with carbon fiber.
The watch is equipped with a triple sensor that provides data on altitude, barometric pressure and temperature to follow you everywhere. And with the position indicator you will always follow the correct direction, even when visibility is limited.
The functions of this model are completed by solar charging and the radio control and smartphone connectivity system for greater precision and reliability.
The double LED lights and sapphire glass also guarantee high readability, so you can always see the time and other data in all light conditions.
For greater attention to the environment, the case, bezel and strap are made of bio-based resins
*Due to the characteristics of carbon fiber reinforced resin, the pattern and color tone that appears on the surface will vary model by model.
