Full Review
Overview
The Withings ScanWatch 2 proves that health tracking does not require a chunky smartwatch. Behind its classic analog watch face lies a suite of medical-grade sensors including ECG, continuous SpO2 monitoring, and skin temperature sensing.
Sleep Tracking
The ScanWatch 2 tracks sleep stages, breathing disturbances, and SpO2 throughout the night. Its Sleep Score combines duration, depth, regularity, and interruptions into an actionable daily metric. The breathing disturbance detection can flag patterns consistent with sleep apnea.
Medical-Grade Features
The ECG function is cleared by the FDA for detecting atrial fibrillation. Continuous SpO2 monitoring can detect breathing disturbances during sleep, and the temperature sensor tracks variations that may indicate illness.
Design
The analog watch face with a small OLED sub-display gives it a sophisticated look suitable for both office and gym. Available in 38mm and 42mm sizes.
Battery Life
Up to 30 days on a single charge, making it one of the longest-lasting health watches available.
Who Should Buy This
Those who want medical-grade health monitoring in a watch that looks like a traditional timepiece, not a gadget.
