This new MUDMASTER model was created especially for those people who work or play in areas where mud, rubble, dirt, and debris are present.
This is CASIO's first analogue watch to come with a Mud Resistant construction, and coupled with a special vibration-resistant construction, this lets the watch stand up to the wear and tear experienced while operating heavy machinery. 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. The screw-in force of the screw lock bezel on an internal gasket further increases mud resistance.
A new bezel structure lets you visually check whether the bezel has been screwed in adequately. In addition, Triple Sensor Version 3 capabilities provide instant access to direction, height,barometric pressure, and temperature information when needed under tough conditions. The face is illuminated by a double LED light and protected by a sapphire crystal to ensure high visibility under virtually any conditions imaginable. The band surface is processed to resemble a cloth band texture, and the military green shade makes it perfect for all environments. Even the hour and minute hands have been designed and shaped with points that make them resemble warning markers. All buttons have a checkered surface for confident operation, and the overall design is tough and rugged.
