Casio launches new feature-loaded watches with carbon and stainless-steel cases
The brown-and-gold Master of G trio we covered as a Casioblog leak back in July is now official. It is arriving under a proper collection name: "Master in Horizon Gold," which Casio frames around the point where "earth meets sky." All three watches share a similar look — light yellow gold ion-plated bezels, brown ion-plated metal accents, bio-based carbon cases, and dark brown bio-based resin bands — but split on function.
The Mudmaster GG-B100XMH-5A skips solar power for a CR2025 battery rated at roughly two years, alongside Bluetooth instead of radio sync. It's the heaviest of the three at 104 grams, and the only one with a step counter alongside its altimeter, barometer, compass, and thermometer. The Mudman GW-9500MH-5 takes a different direction entirely — Tough Solar plus Multi-Band 6 radio time correction, no Bluetooth at all, running the same triple-sensor suite through a duplex LCD display, at 88 grams. The GravityMaster GR-B300H-5A is the lightest of the bunch at 71 grams and the outlier spec-wise, since it skips the ABC sensors in favor of dual time zones, a screw-lock crown, and a rotary disc indicator at 9 o'clock that doubles as a stopwatch and battery gauge — solar-powered and Bluetooth-equipped, like the Mudmaster.
Confirmed Japan pricing lands below where the leak had estimated: ¥60,500 (about $383) for the Mudmaster against an earlier $460 guess, ¥63,800 (~$404) for the Mudman versus a projected $440, and ¥49,500 (~$314) for the GravityMaster, close to but still under the leaked $320 figure.
This isn't Casio's first color-mathcing trio across these three lines — 2024's orange-and-yellow "Emergency Colors" release followed the same format, with a Mudmaster, Mudman, and GravityMaster under one shared palette — so a wider international rollout beyond Japan is likely to follow.
