Casio has introduced three new Master of G watches in the United States, part of the Horizon Gold collection that debuted in Japan last month.
The lineup includes the Gravitymaster GRB300H-5A, Mudmaster GGB100XMH-5A, and Mudman GW9500MH-5, all available on Casio's US website.
Design and Pricing
The Horizon Gold finish features light yellow-gold ion-plated bezels, brown metal accents, and dark brown bio-based resin bands.
These updates are purely cosmetic, with core hardware and features unchanged from standard models.
The Gravitymaster GRB300H-5A is the most affordable at $330, featuring a carbon fiber-reinforced resin case, analog dial with dual-time display, and a rotary indicator for battery, stopwatch, and alarm status.
It supports Tough Solar charging and Bluetooth connectivity with the Casio Watches app for automatic time adjustment.
The Mudmaster GGB100XMH-5A costs $460 and includes a stainless steel bezel with a mud and dust-resistant case.
Its quad-sensor system provides compass, altimeter/barometer, thermometer, and step counter, while Bluetooth enables altitude and route logging.
It runs on a CR2025 battery with an estimated two-year lifespan.
The Mudman GW9500MH-5 is priced at $440, featuring a mud and dust-resistant case, duplex LCD, and Triple Sensor for compass, altitude/barometric pressure, and temperature readings.
It operates on solar power and uses Multi-Band 6 radio signals for automatic time calibration.
All three models retain standard G-Shock specifications, including 200-meter water resistance, shock-resistant construction, daily alarms, and LED illumination.
