This is the latest addition to the MASTER OF G MUDMASTER Series. Built to prevent intrusion by sand, mud or dust and to ensure reliable operation in the harshest environments, this tough structure is prepared to support training and actual missions in environments such as jungles and deserts. It's an ideal tool for rangers and rescue crews. Mud Resist construction helps to ensure that nothing gets into the watch when down and dirty work takes you deep into the dirt and sludge. Multiple gaskets are used on the pipes that guide buttons and shafts, which keeps mud out. These pipes not only act to protect buttons from impact, they also enhance button operation.
