Evidence-based evaluation by medical professionals

"A sophisticated hybrid watch that bridges the gap between traditional aesthetics and advanced medical-grade health surveillance, featuring an industry-leading 35-day battery life."
Strong Clinical Evidence Highly Recommended

Score

The Withings ScanWatch 2 (Model HWA10) is a premier hybrid smartwatch that integrates advanced clinical sensors into a timeless analog design. Its core medical utility centers on the Scan Monitor, which is FDA-cleared for recording single-lead ECG rhythms to detect Atrial Fibrillation (AFib). Clinical validation in a study of 262 subjects demonstrated a 96.3% sensitivity for AFib detection and 100.0% specificity for normal sinus rhythm. Beyond its EKG capabilities, the device features the TempTech 24/7 module, which uses a heat-flux sensor and a temperature sensor to provide continuous baseline temperature variations. It also passively monitors for irregular heart rhythms via a multi-channel PPG sensor and tracks blood oxygen (SpO2) levels. Designed for health-conscious adults (22+ in the U.S.), the ScanWatch 2 offers a 'spot-checking' approach to health monitoring, providing professional-grade PDF reports for easy data sharing with clinicians. While its grayscale OLED screen is minimal, its 35-day battery life ensures near-continuous health data collection that few other smartwatches can match.
