Casio G-Shock Master of G Mudmaster GG-1000-1A5ER

This model belongs to the prestigious G-SHOCK Mudmaster series, uses carbon materials, and has been specifically designed to operate in the most extreme environments, riddled with earth, rubble, and debris. By pressing a single large button at 3 o'clock, you can check your position thanks to the integrated Compass. The temperature can also be easily detected by pressing the button located at 4 o'clock. The entire watch has been developed with operability as the top priority, so that anyone can intuitively control direction via the Compass, even in the most prohibitive climates and without the need for direct visual contact. The cylindrical structure protecting the buttons, totally resistant to dust and mud, prevents fine sand and debris from penetrating the mechanisms, while also helping to absorb accidental impacts and improving ergonomics. To maximize legibility, enlarged hour and minute hands have been adopted, combined with indexes with large Arabic numerals. The design is rich in tactical and military-inspired details, including a gear mode indicator that uses a cogwheel-like disc dial, and a heavily textured strap to prevent any slippage on the wrist.
