Push it even further with the G-SQUAD GBD-H2000 — a selection of G-SHOCK multi-sport watches with heart rate monitor and GPS. These watches come packed with functions for tracking all kinds of workouts. Measure your heart rate with the optical sensor; use the accelerometer to count steps; and take swimming sessions up a notch with a gyroscope that detects strokes and turns. Not only that, sensors that detect orientation, altitude/atmospheric pressure, and temperature help you navigate through whatever you do. With a 53mm resin case and a water resistance of 200 metres, this watch is durable through any condition.
