The Casio G-Shock Mudmaster is a dust- and mud-resistant multi-function watch.
The case of the Mudmaster features an elaborate case construction allowing for its superior dust- and mud resistance. The crown is protected by a highly airtight screw-lock structure; the oversized buttons feature a cylindrical guard structure. The movement ('module') is protected by Alpha Gel to protect the watch from malfunctions or damage from vibrations, while washers securing the lug screws help prevent vibrations from loosening the strap.
Its 'Triple Sensor Technology' allows it to measure directions, atmospheric pressure, altitude and temparature. When engaged, the digital compass indicates North through a hand, with bidrectional calibration and magnetic declination correction. The altimeter has a measuring range of -700 to 10.000 meters (-2.300 - 32.800 ft) using measuring units of 1 meter (5 ft). The barometer can be set to hPa or inHg and -amongst other things- alerts the user of significant changes in presure. Being a Casio G-Shock, these represent just a small amount of its functions.
