A molten-hot rumor is bubbling up for G-Shock fans: a magma-themed Casio G-Shock Mudmaster is reportedly on the horizon. Believed to carry the model number GWG-B1000MG-1A9, the new variant would expand the GWG-B1000 line that debuted in October 2023 with the GWG-B1000-1A, GWG-B1000-3A, and GWG-B1000-1A4, followed by the GWG-B1000EC-1A in 2024 as part of the Emergency Colors collection.
The “1A9” suffix typically points to a black-and-gold or black-and-orange palette. Given the lava-inspired theme, expect a dramatic black-and-orange look that fits the name. As with the rest of the Master of G Mudmaster family, durability and utility should be the headline acts.
The Casio G-Shock Mudmaster GWG-B1000 platform (also referred to as GWGB1000) is built for hostile environments and hard use:
– Multiband 6 radio-controlled timekeeping and Bluetooth connectivity
– Shock, vibration, and mud resistance with Carbon Core Guard structure
– Triple sensor suite: compass, barometer, altimeter, and thermometer
– World time, stopwatch, countdown timer, and daily alarm
– Sunrise and sunset times for location-aware planning
– Tough Solar charging to extend battery life between exposures to light
According to the latest whispers, the G-Shock Mudmaster GWG-B1000MG-1A9 could arrive sometime in 2026, though the exact release window remains unclear. Pricing is tipped between £700 and £800, roughly $922 to $1,053, signaling a small premium over earlier models that typically retail around £699 (about $800).
As with any pre-launch leak, nothing is official until Casio confirms it. Still, a magma-themed GWG-B1000MG-1A9 sounds like a perfect fit for the rugged Master of G lineup—especially for anyone who wants field-ready specs wrapped in a fiery, attention-grabbing design. Stay tuned for confirmation on the final colorway, release date, and price.
