The Withings ScanWatch Horizon is a hybrid smartwatch that blends the aesthetics of a classic diving watch with advanced health monitoring features. It includes clinically validated ECG and SpO₂ measurements, continuous heart rate tracking, and sleep monitoring. Unlike many smartwatches, it offers up to 30 days of battery life, making it highly practical for long-term use. As a niche French health-tech manufacturer, Withings emphasizes strict data protection measures, including GDPR compliance and encrypted cloud storage.
