Overview
The Withings ScanWatch 2 is a hybrid smartwatch that marries classic Swiss watch design with advanced medical-grade health sensors. It features a 316L stainless steel case, sapphire crystal glass, and analog hands alongside a small OLED display for health data. It offers single-lead ECG for atrial fibrillation detection, SpO2 monitoring, and a new temperature sensor for improved cycle tracking and fever detection at $349.
Design & Build
The ScanWatch 2 is a beautiful timepiece that can pass as a traditional analog watch. The 316L stainless steel case is available in 42mm and 38mm sizes, with sapphire crystal glass protecting both the analog dial and the small OLED display. The analog hands are available in several styles, and the watch faces are replaceable with standard 20mm (42mm) or 18mm (38mm) bands. The OLED display remains off most of the time, activating only when you press the crown or receive a notification. Build quality is exceptional, with the weight and feel of a premium mechanical watch. The 5 ATM water resistance is suitable for swimming.

Performance
The ECG sensor provides medical-grade single-lead electrocardiogram readings that can detect atrial fibrillation. The FDA-cleared algorithm provides results in 30 seconds. SpO2 monitoring tracks blood oxygen levels during sleep and on demand. The new temperature sensor improves menstrual cycle tracking and can detect fever trends. Sleep tracking is comprehensive, with automatic sleep stage detection and Sleep Apnea Detection using the SpO2 sensor. Battery life is a standout at up to 30 days, far exceeding any full smartwatch. The watch stores up to 21 days of data locally before needing to sync to the app.
Features
Withings Health Mate app provides a clean dashboard for all health metrics, including heart rate, SpO2, sleep, activity, and weight from Withings smart scales. The watch tracks steps, distance, calories, and automatically detects walking, running, swimming, and cycling. Smart notifications are subtle with vibration alerts and the ability to read messages on the OLED display. Withings Pay supports contactless payments. The watch includes an altimeter for floor counting and an ambient light sensor. It also supports automatic time zone updates and sunrise/sunset times based on location.
