This new model joins the G-SHOCK sports line, the G-SQUAD. It now features Bluetooth smartphone connectivity. By linking with your smartphone's GPS function, distance measurement using the accelerometer is calibrated. Once calibrated, the watch can measure more accurate distance from the next time you run. By linking this distance measurement with running time measurement, you can measure your running pace, and it also features an auto-lap function that automatically measures your time after each set distance run. Along with the existing step tracker (step counting function), interval timer (up to 5 x 20 sets), lap time measurement (up to 140 x 100 runs), and calorie burn measurement, this watch supports your daily training.
