GSTB1000D-3A

Tough, innovative, functional beauty — reimagined in sharp, minimalist style.

The GSTB1000D carries on the G-SHOCK heritage of tough construction and design rooted in functional beauty, reconstructing this legacy to achieve a polished, sleek expression.

The bezel goes logo-free for a clean, modern look, while three separate finishes — vertical hairline, circular hairline, and mirror polishing — create a rich and sophisticated textural appeal that changes as light is reflected at different angles. The mirror- and hairline-finished solid stainless-steel band is paired with a tri-fold clasp also crafted from solid stainless steel. This sharp, flat design takes you from business meetings to casual settings to outdoor activities with ease.

This is a timepiece built to be tough. A metal bezel guards against impact, while the carbon-reinforced resin case protects the module. Urethane buffering components where the metal band meets the case absorb shock and reduce stress on the joints — enhancing durability and ensuring a more secure connection. Adhesive glass bonding and a compact module design make for a slimmer, lighter watch, without compromising shock resistance. All of this comes together in an exacting combination of comfort, toughness, and everyday usability.

Compact form, minimalist design, and rugged performance — this timepiece is an all-around companion, ready for whatever comes your way.
