Withings ScanWatch 2 looks like a traditional watch and works like a medical-grade health monitor.

The stainless steel case and sapphire glass give it a refined, timeless look you can wear everywhere — while under the surface, it's running continuous health scans around the clock.

The HealthSense 4 platform monitors 35 health parameters with advanced algorithms, including a clinically validated ECG for atrial fibrillation detection, SpO2 overnight tracking, 24/7 skin temperature with workout temperature zones, and Irregular Rhythm Notifications throughout the day and night.

Sleep tracking now includes REM phase detection alongside all other sleep stages, and the Breathing Quality Index monitors respiratory rhythm overnight. The HRV-powered Vitalité Indicator synthesizes all of that data into a single daily readout — telling you when to push, restore, or take extra care.

Women's health features include enhanced temperature-based cycle tracking that retrospectively confirms ovulation windows and works through perimenopause and menopause. Connected GPS tracks outdoor routes via your phone.
