Casio Expands Its G-Shock Master of G Lineup in Europe With New Mudmaster, Mudman, and Gravitymaster Watches
Casio has officially expanded its latest G-Shock Master of G collection into Europe, bringing three rugged new models to outdoor adventurers, aviation fans, and everyday watch enthusiasts who want durability with serious functionality. The new lineup includes the G-Shock Mudmaster GG-B100XMH-5A, Mudman GW-9500MH-5, and Gravitymaster GR-B300H-5A.
The collection first appeared in Japan earlier in August, and its arrival in European markets confirms a wider rollout for Casio’s newest tough-watch trio. Each model carries the unmistakable Master of G identity, combining shock-resistant construction with purpose-built features for demanding environments.
All three watches share a coordinated design theme, featuring a light yellow gold ion-plated bezel, brown detailing, and a dark brown resin strap. The result is a rugged yet refined look that feels ready for the trail, cockpit, or daily wear.
The Mudmaster GG-B100XMH-5A is the most robust model in the new European lineup. Weighing 104g, it features a stainless steel bezel, a carbon fiber-reinforced resin case, and Casio’s Carbon Core Guard structure. Built for challenging outdoor conditions, it is resistant to mud, dust, shocks, and water up to 200 meters.
This model is also packed with practical tools for explorers and field use. It includes a digital compass, altimeter, barometer, thermometer, and step counter. Bluetooth support allows the watch to connect with the Casio Watches app, enabling automatic time adjustment and Mission Log functionality for tracking activity data.
For those who prefer a tough outdoor watch with solar power and radio-controlled accuracy, the Mudman GW-9500MH-5 stands out. At 88g, it is slightly lighter than the Mudmaster but still built for harsh conditions with mud resistance, dust resistance, shock resistance, and 200-meter water resistance.
The Mudman includes Casio’s Triple Sensor technology, giving users access to compass direction, altitude, barometric pressure, and temperature readings directly from the wrist. It does not include Bluetooth connectivity, but it makes up for that with Tough Solar charging and Multi Band 6 radio-controlled timekeeping. Its duplex LCD display is designed to make outdoor data easier to read at a glance.
The lightest model in the group is the Gravitymaster GR-B300H-5A, weighing 71g. Designed with aviation in mind, it uses a carbon-reinforced case and Carbon Core Guard construction. Casio says its smooth bezel design takes inspiration from next-generation aircraft, giving the watch a modern and technical appearance.
The Gravitymaster includes Bluetooth connectivity, Tough Solar charging, dual-time support, and flight log features. A rotary disc at the 9 o’clock position serves multiple roles, including status display, stopwatch indicator, and battery level indicator. This makes it a strong option for frequent travelers and aviation-focused G-Shock fans.
European pricing starts at €299 for the Gravitymaster GR-B300H-5A. The Mudman GW-9500MH-5 is priced at €399, while the Mudmaster GG-B100XMH-5A sits at the top of the range at €419. In the UK, availability is currently limited to the Mudmaster GG-B100XMH-5A, where it is priced at £365.
The three models are listed across several European markets, including Germany, France, Spain, the Netherlands, Sweden, Italy, Portugal, Norway, and other regions.
With this launch, Casio continues to strengthen its G-Shock Master of G lineup with watches built for real-world toughness. Whether buyers want a mud-resistant outdoor tool, a solar-powered digital adventure watch, or a lightweight aviation-inspired model, the latest Master of G collection gives European G-Shock fans three distinctive new choices.
