Casio G-Shock Mudmaster GWG-B1000MG-1A9ER Men's Watch Gold-Tone • Sapphire Crystal • Solar & Radio-Controlled

The Casio G-Shock Mudmaster GWG-B1000MG-1A9ER is an exceptional sports watch from the flagship MASTER OF G line. Under the name "Magma Gold", it combines rugged extreme protection with a striking aesthetic inspired by flowing magma and solidified rock layers. The case, crafted from bio-based resin with a forged metal outer shell and the patented Carbon Core Guard structure, delivers maximum shock resistance while keeping weight to a minimum. Indices and hands glow in vivid shades of red and orange, while ion-plated metal components in varying gold tones accentuate the watch's structural beauty.

As a solar- and radio-controlled timepiece, the GWG-B1000MG automatically synchronises to the precise radio time signal and is continuously powered by light. The integrated Triple Sensor measures bearing, altitude, barometric pressure and temperature — indispensable for use in extreme conditions. The scratch-resistant sapphire crystal and dual LED illumination ensure reliable legibility in any weather. The position indicator at the 3 o'clock position aids navigation even in reduced visibility, such as during sandstorms.
