Casio G-SHOCK G-STEEL GST-B1000D-1AJF – Japan Domestic Genuine Model
Tough, innovative, functional beauty — reimagined in sharp, minimalist style. The GST-B1000D carries on G-SHOCK's heritage of tough construction and functional design, reconstructing that legacy into a polished, sleek metal expression. The bezel goes logo-free for a clean, modern look, with three separate finishes — vertical hairline, circular hairline, and mirror polishing — creating a rich, sophisticated textural appeal that shifts as light hits it from different angles. The mirror- and hairline-finished solid stainless steel band pairs with a tri-fold clasp, also crafted from solid stainless steel, for a sharp, flat design that moves easily from business meetings to casual outings to outdoor activities. The inset dial features accent colors inspired by the first G-SHOCK: red for the passion to take on challenges, blue for water resistance, and yellow for outstanding shock resistance.
