The Wellograph Sapphire Wellness Watch is no ordinary activity tracker - it encourages you to exercise, breathe hard, and break a sweat. The sleek, stylish design conceptualizes a healthy heartbeat and represents it through gentle convex surfaces like the domed crystal surface. On the back you will find the unique technology - a Tri­-LED Heart Rate Sensor integrated into a soft spherical surface, which replicates the action of a doctor using his/her fingertip to feel a pulse, allowing for accurate heart signals. You can view your resting heart rate lower over time as you increase your fitness level.
