Withings makes hybrid smartwatches that look like fine timepieces and work like medical-grade health monitors. Founded in France and developed in collaboration with leading hospitals and universities, Withings ScanWatch is the only hybrid watch cleared to perform a medical-grade ECG, detect atrial fibrillation, track blood oxygen, respiratory health, and body temperature — all with an analog watch face and up to 30 days of battery life.

The ScanWatch lineup includes the ScanWatch 2, ScanWatch Light, ScanWatch Nova, and ScanWatch Nova Brilliant — spanning everyday wellness to premium health monitoring. All Withings devices are directly HSA/FSA eligible at checkout, making them one of the most accessible medically-focused wearables on the market.
