Casio GBD-200-9ER

The Casio GBD-200-9ER represents the G-Squad line's commitment to serious training functionality wrapped in bold yellow aesthetic. This isn't watch with fitness features added as afterthought—it's purpose-built training tool with accelerometer, distance measurement, and Bluetooth smartphone linkage designed specifically for runners and workout enthusiasts. The yellow colour makes statement whilst the square digital face prioritises legibility during activity.

The accelerometer tracks steps, distance, and pace without requiring smartphone GPS during runs. The dedicated Bluetooth connection links to the G-SHOCK MOVE app, syncing workout data automatically. Life log functionality tracks daily steps and calorie consumption beyond structured workouts. Training history builds over time, providing insights into progress and patterns. The step tracker mode remains active continuously, capturing everyday movement alongside dedicated exercise sessions.

The square digital display shows workout data clearly at glance—no struggling with tiny text or insufficient contrast during activity. The dedicated run mode captures pace, distance, and time simultaneously. Interval training gets proper support through programmable timer. The countdown and stopwatch functions handle circuit training and timed exercises. The multi-alarm capability helps schedule workout timing.

Shock resistance handles the impacts that running, CrossFit, or outdoor training deliver. Water resistance to 200 metres covers swimming workouts and outdoor training in rain. The resin case and band shed sweat and moisture easily—quick rinse restores cleanliness. The yellow colour shows dirt readily but cleans effortlessly with damp cloth.

Battery life approaches 2 years with regular Bluetooth use and workout tracking—impressive runtime given the connectivity and sensor activity. The backlight remains visible during early morning or evening runs. The watch face can be customised through the app to prioritise preferred metrics.

This GBD-200-9ER serves serious fitness enthusiasts who want proper training data without smartwatch complexity or daily charging. The G-Squad approach combines G-Shock toughness with genuine training functionality. Essential kit for those whose workouts demand more than basic step counting.
