This new MUDMASTER model was created especially for those whose work takes them to areas where piles of rubble, dirt, and debris are present. A special vibration-resistant construction lets them stand up to wear while operating cutters, crushers, drills and other heavy machinery to clear way large obstacles. This is CASIO's first analog watch to come with Mud Resist construction, which 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. The screw-in force of the screw lock bezel on an internal gasket further increases mud resistance.

    Excellent watch

    Bought this for myself as a Christmas present and have zero regrets.

    It's going to take me some time to learn all the features.

    Very happy with my purchase.

    1st time G Shocker

    First time giving a G Shock a go. I typically only wear automatic divers watches but figured everyone needs at least one G Shock in their collection. It wears large even for a big wrist but comfortable. Love the analogue face with minimal digital screen and was one of the main reasons I went with the Mudmaster. Have found the features really handy.

    Never bought from Watch Direct before but purchase was smooth with no issues and good postage speed and packaging. Would have no hesitation buying from them again.
