About This Item
The G-SHOCK GA-100-1A1 delivers a bold blackout design paired with the toughness and functionality the GA series is known for. Its combination analog-digital layout features a powerful millisecond stopwatch and speed measurement capabilities for high-precision timing. JIS Class-1 magnetic resistance protects the movement from interference, while the lightweight aluminum hands and four large digital displays create a dynamic, high-visibility face layout. With shock resistance, 200-meter water protection, and a rugged case shape built for impact, this model is engineered for reliability in demanding environments. The all-black finish and oversized silhouette make it a standout choice for everyday wear, training, outdoor activity, and professional use.
