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.
