ScanWatch Nova isn’t just a snazzy dive-style watch with health tracking – it’s a medical-grade electrocardiogram. Its upgraded PPG heart rate sensor makes this even more accurate than the original. It can reliably detect potentially serious heart rate irregularities, including atrial fibrillation. And you can relax because you’ll be notified in real-time, 24-7. And you’ll sleep soundly too, with clinically validated SpO2 keeping a watchful eye.
