A featherweight, minimalist reinterpretation of the iconic 1983 G-SHOCK silhouette, the GAC-2500-1A distills legendary G-SHOCK toughness into a clean, all-black analog design. Crafted from durable bio-based resin from bezel to strap, this slim 12.7 mm timepiece tips the scales at just 47 grams—delivering effortless all-day comfort for streetwear, travel, and outdoor adventures.
Minimalist Three-Dimensional Analog Design
The stealthy black resin dial features raised bar indexes that echo the parallel lines of the hands and octagonal case. A dedicated small seconds subdial at 9 o'clock—detailed with the signature Shock Resist mark on the tail of the hand—sits opposite a color-matched, fan-shaped three-cell date window at 3 o'clock that doubles as an elapsed-minute counter in stopwatch mode. When you need an unobstructed view of the subdials, the hand-shift function smoothly moves the hands aside. Finished with Neobrite luminous hands and a warm amber LED backlight, the dial stays legible day or night.
Engineered for Impact
Built with a shock-resistant bio-based resin case and bezel, the GAC-2500-1A is engineered to withstand heavy knocks and harsh conditions. Equipped with Casio’s Shock Release Hand technology, the minute hand uses a magnetic holding structure to absorb and dissipate impact energy, automatically returning to its proper position if jarred—delivering true G-SHOCK resilience in an ultra-light analog format.
