Casio releasing new G-Shock Mudmaster triple sensor watch in Europe

The upcoming Casio G-Shock Mudmaster GWG-B1000MG-1A9 watch is set for release in Europe. This watch has been rumored since late 2025, with various images of the model appearing earlier in 2026.

Now, French retailer David et Philly suggests that the Casio G-Shock GWG-B1000MG-1A9 will be released in the EU in June 2026. In this market, it will retail for €899. Another reputable source, morgan_gshock on Instagram, indicates that this magma-themed watch will be launched in Japan in May 2026, with an RRP of ¥143,000.

The G-Shock GWG-B1000MG-1A9 watch’s listing at the European retailer includes some new and clearer images of the product (below). As shown in the earlier leaked images, this model has a black precision-forged metal casing, reinforced with a carbon fiber structure, and a gold ion-plated bezel. Set against the dark dial are red and orange tone hands and hour markers, tying in to the magma theme. Plus, it has a marbled black resin strap.

The David et Philly page also appears to confirm the specifications of the watch. This mud and shock resistant model features a Triple Sensor: a compass, a thermometer and an altimeter/barometer. Bluetooth connectivity allows you to access more features in the Casio Watches app. Plus, this radio-controlled watch has a dual LED backlight and Tough Solar charging technology.

Whether or when the Casio G-Shock Mudmaster GWG-B1000MG-1A9 watch could be officially released in the US remains to be seen.
