Designed for professionals who work in the harshest environments, the G-Shock Master of G watch line introduces the Mudman with three sensors and mud-resistant construction. The large, easy-to-use front button and three direct sensor buttons on the side are shaped to deflect mud and water and are protected by cylindrical stainless steel components. The button shafts are fitted with seals to keep mud and dust out too, so you're ready for the toughest off-road conditions.
