Casio’s next Mudmaster is still unofficial, but the GG‑B100X looks to be an incremental, materials‑and‑display‑focused refresh of the Bluetooth Mudmaster rather than a clean break from the current GG‑B100. New renders circulating via @geesgshock show a familiar case silhouette, sensor layout and analog‑digital dial, wrapped in updated bezels and what appears to be a darker, higher‑contrast LCD window.
Side‑by‑side close‑ups of the digital display suggest the GG‑B100X will likely keep the same segmented layout but shift to a deeper black background with warmer digits - so we can expect an improved LCD stack or MiP‑style treatment. The pixel structure still looks closer to classic Casio negative LCD than to the finer dot‑matrix panels on confirmed MiP G‑Shocks (like the GW-BX5600), so any upgrade here is likely evolutionary, not transformative.
Aside from that, the leaked images support earlier claims of forged‑carbon or carbon‑composite bezels on at least one variant, alongside a brushed metal‑guard model that would make the "X" line the more premium expression of the platform. Model numbers reportedly include GG‑B100X‑1A, GG‑B100X‑1A3, GG‑B100X‑1A9 and GG‑B100XM‑1A, just like the color logic of the 2019 range. There's also a modest UK price bump expected, to around £350-£375 (~$472-~$506).
Core functionality wise, the watch is still described as a quad‑sensor Mudmaster with compass, altimeter/barometer, thermometer, step counter and Bluetooth link, sitting between the GG‑1000 and GWG‑2000 in Casio’s off‑road hierarchy. Solar charging and launch timing is still iffy, and until Casio publishes an official product page, all of these details should be treated as informed leaks rather than confirmed specifications.
