The Casio G-Shock G-Squad GBD200-1 is where legendary G-Shock toughness meets serious fitness functionality. Designed for athletes and active wearers who demand more from their wrist, this all-black square-case watch delivers a powerful suite of training tools wrapped in a slimmer, more wearable profile than its predecessors.

At 48.4mm x 45.9mm x 15mm and weighing just 58 grams, the GBD200-1 is thinner than previous G-Squad MOVE models, making it genuinely comfortable for all-day wear and active workouts alike. The soft urethane band features a wave-shaped form to prevent sticking to skin, ventilated lugs for breathability, and extra band holes for a precise, personalised fit — thoughtful details that make a real difference during training.

Via Bluetooth, the watch links to your smartphone's GPS for quicker and more accurate distance calibration, going well beyond what the onboard accelerometer can achieve alone. Training data is displayed and tracked across an impressive range of metrics including distance, speed, pace, lap times, average pace, calories burned, and more — with customisable training display screens so you see exactly what matters most. The built-in Auto Lap feature and interval timer make it equally capable for casual joggers and dedicated runners, while training logs store up to 100 runs with up to 140 lap records per run. A daily step counter and monthly running distance summary round out the life-logging features.

Watch vibrations alert you to training milestones, incoming calls, emails, and social media notifications from your linked smartphone. The high-definition MIP LCD ensures data stays sharp and readable in any conditions, backed by a Super Illuminator LED backlight with auto light switch for night training.

Shock resistant and water resistant to 200 metres, world time across 38 time zones, and an approximate two-year battery life complete the package. The GBD200-1 is the ultimate training companion for those who refuse to compromise on toughness or performance.
