Description
The Casio G-Shock Mudmaster GG-B100-1A3DR represents the pinnacle of tactical watch engineering, designed for the most demanding terrestrial environments. This formidable timepiece combines advanced sensor technology with military-grade construction, delivering exceptional functionality for professionals and outdoor enthusiasts who require unwavering reliability. The black dial with high-contrast luminous Arabic numerals at 12, 3, 6, and 9 o'clock ensures instant readability, while yellow accent details and the signature Mudmaster branding reinforce its rugged aesthetic. At Cassims & Co., we are proud to be an authorised retailer of CASIO watches, ensuring every G-Shock Mudmaster comes with full international warranty and genuine provenance.
The GG-B100-1A3DR is equipped with Casio's revolutionary Quad Sensor technology, incorporating a compass, thermometer, altimeter/barometer, and step counter — four critical instruments integrated into one shock-resistant package. Bluetooth connectivity enables seamless pairing with your smartphone for automatic time synchronisation and access to over 300 world cities through the dedicated G-Shock Connected app. The Carbon Core Guard structure utilises carbon fibre reinforcement in the bezel, creating an exceptionally strong yet lightweight case that measures 55.4 × 51.3 × 19.4 mm. The olive green textile and resin hybrid strap features a herringbone weave pattern that combines comfort with durability, while the protective button guards and mud-resistant construction ensure operational integrity in the harshest conditions.
Built to military specification, this Mudmaster offers 200-metre water resistance and comprehensive shock protection, making it equally at home in desert expeditions, jungle treks, or urban tactical operations. The dual-layer LCD display provides both analogue and digital readouts, with the digital window offering access to sensor data, world time, five daily alarms, and a full auto-calendar programmed to the year 2099. LED backlighting with afterglow ensures visibility in complete darkness. Our watch servicing and repairs team is always available to support your Mudmaster throughout its operational life, from battery replacements to technical service.
Whether you're navigating uncharted terrain or simply demand a watch that can withstand anything your lifestyle throws at it, the GG-B100-1A3DR delivers uncompromising performance. Visit us at our Mall of the South boutique to experience this exceptional timepiece first-hand, or take advantage of our secure nationwide delivery service across South Africa. This is G-Shock engineering at its most sophisticated — a tool watch in the truest sense.
Care guide
- Clean the case, bezel, and strap regularly with a soft, lint-free cloth slightly dampened with fresh water, especially after exposure to saltwater, mud, dust, or chemicals.
- For stubborn dirt on the resin and textile strap, use a soft brush with mild soap and lukewarm water, then rinse thoroughly and air dry completely before wearing.
- Avoid exposing the watch to extreme temperatures (below -10°C or above 60°C), strong magnetic fields, or harsh chemicals including solvents, petrol, cleaning agents, and insect repellents, which can damage the resin components.
- After saltwater exposure, rinse the watch thoroughly with fresh water and ensure all buttons and sensors are cleaned to prevent corrosion and maintain mud-resistant integrity.
- Do not operate the buttons or crown while the watch is wet or submerged, as this can compromise water resistance and allow moisture ingress.
- Store the watch in a cool, dry place away from direct sunlight when not in use, as prolonged UV exposure can cause resin discolouration over time.
- Have the battery replaced by authorised technicians when the low battery indicator appears, and request a water resistance test after any battery replacement to ensure gasket integrity.
- The Bluetooth connection range is optimal within 2 metres of your smartphone; ensure the G-Shock Connected app is updated to the latest version for best performance.
- Avoid dropping the watch or subjecting it to severe impacts beyond normal G-Shock shock resistance parameters, particularly direct impacts to the crystal or sensors.
- The compass sensor requires periodic calibration for accuracy; follow the instructions in the user manual or via the smartphone app to perform compass calibration, especially when travelling to different geographical regions.
