Five new Casio G-Shock Mudmaster watches coming soon to UK

Casio has officially confirmed that the new G-Shock Mudmaster GG-B100X watches will soon be released in the UK. These five models were recently launched in Japan following a series of rumors.

This Casio G-Shock Mudmaster range roughly splits into two sections. The first are Casio G-Shock GG-B100X watches, which have a carbon fiber bezel. The GG-B100X-1A is an all black model, the GG-B100X-1A3 has a khaki strap and black casing, and the GG-B100X-1A9 has a vivid orange band accompanying the watch. The second category is the GG-B100XM watches, which have metal bezels. The GG-B100XM-1A has a black body and silver bezel, while the GG-B100XMB-1A has a black ion-plated stainless steel bezel.

Now, at the Casio online store in the UK, you can find product listings for these new G-Shock Mudmaster watches. All are set for release in February 2026; if you want to receive an email notification on launch, you can sign up on each product page. The three Casio G-Shock GG-B100X watches will retail for £349.00, while the two GG-B100XM watches have a higher RRP of £369.00. As usual, these prices are subject to change.

Casio’s GG-B100X watch is an upgraded version of the GG-B100 range, launched in 2019. While the designs are similar, the refreshed model features a newer 5744 module. This brings a new Location Indicator and Location Memory tools, accessed via the Casio Watches app when the watch is connected to a smartphone via Bluetooth. Plus, the standard resin, used for the casing and strap, has been switched out for a bio-resin alternative.

Features of the GG-B100 include a digital compass, an altimeter, a barometer, a thermometer and a step counter. These mud-resistant and water resistant watches also support world time, and have basic functions like alarms, a stopwatch and a timer. It is worth noting that the new module does not appear to be more efficient than its predecessor, with Casio estimating a two year battery life for this model. Whether or when they could be released more widely in Europe or in North America is unclear.
