GST-W1000D-3A G-STEEL GST-W1000 Series

The GST-W1000 reimagines the G-SHOCK pursuit of toughness with a minimalist design shaped by contemporary sensibilities. 

Crafted in stainless steel, the exterior embodies a reductionist aesthetic. Minimizing the bezel lugs and integrating them with the bracelet creates a seamless flow of metal surfaces, delivering balanced proportions and a stable, comfortable fit on the wrist. Four distinct finishes — mirror, circular hairline, straight hairline, and honing — bring out the hard, refined texture of the metal. The multi-hand dial, featuring three inset dials, pairs long, sharply defined hour and minute hands with phosphorescent indexes for excellent readability. Together, these elements give the watch a clean, refined appearance.

At its core is TOUGH MVT.2, an evolution of the original Casio solar-powered analog movement with auto time adjustment. Along with Bluetooth® connectivity, Multiband 6 radio-controlled timekeeping, and Tough Solar charging, TOUGH MVT.2 incorporates self-regulating features that detect strong impacts and magnetic fields and automatically correct hand positions, delivering dependable timekeeping from everyday wear to more demanding situations.

Every element of this watch’s structure, design, and functionality comes together to mark every moment with beauty. From business settings to casual wear and outdoor activities, the GST-W1000 is an all-around timepiece that transitions effortlessly across all the scenes of contemporary life.
