Withings ScanWatch 2 42mm Blue

The Withings ScanWatch 2 is a hybrid smartwatch for comprehensive health tracking day and night. It combines precise sensors with HealthSense 4™ software to enable continuous monitoring of key vital signs. With advanced analytics, temperature functions, and heart rhythm monitoring, it provides a holistic view of fitness, sleep, and well-being—with a battery life of up to 35 days.

Advanced sensors and software
The fourth generation of proprietary HealthSense™ operating software uses machine learning directly on the watch and processes data from the latest 16-channel multi-wavelength photoplethysmogram (PPG) sensors. Together with the new TempTech24/7 module, which integrates four sensors for measuring heat flow, thermistor values, movement, and pulse, the ScanWatch 2 delivers accurate temperature, activity, and health data.

Your health guide – day and night
The PowerSense™ Pro system (Gen 3) automatically detects when the watch is being worn, tracks sleep and wake cycles, and optimizes energy consumption. In addition, ActivitySense 2 provides improved activity recognition with over 40 automatically tracked exercise types. With the help of special measurements, the ScanWatch 2 allows you to improve your cardiovascular fitness. It features Connected GPS and an altimeter for floors climbed, and can evaluate your performance based on heart rate zones and fitness level measurements via maximum oxygen uptake (VO2max). At night, the watch collects measurements on sleep metrics, breathing rate and disturbances, and average blood oxygen levels during sleep to detect sleep apnea.

Heart health
The ScanWatch 2 is not only a valuable companion for sports, but also helps you keep an eye on your health despite the stresses of everyday life. It monitors your heart rate day and night and notifies you if your heart is beating too fast or too slow. If there are fluctuations in your heart rhythm, the smartwatch can record a medically accurate 1-channel electrocardiogram (ECG). Immediate ECG results are displayed on the watch screen and can be viewed in the Withings app. The app also provides a detailed diagnostic report that includes passive signs of atrial fibrillation and relevant information.

Continuous body temperature tracking
Thanks to the TempTech24/7 module, changes in core body temperature during the day and night can now be recorded, which may indicate the onset of an illness or other health condition. The measurements also help to increase performance and recovery by determining body temperature zones during exercise.

Sleep analysis and activity logging
Improved algorithms enable accurate measurements of sleep quality, duration, and phases—including a new REM sleep analysis. The watch also tracks breathing disturbances, breathing rate, and average SPW during the night. In everyday life, ScanWatch 2 offers advanced activity tracking with heart rate zones, estimated maximum oxygen uptake (VO₂max), active minutes, calorie consumption, and distance measurement via Connected GPS. Progress can be viewed directly on the watch, and manual activities and menstrual logs can be recorded discreetly at any time.

Cycle tracking
The ScanWatch 2 also offers the option of monitoring your menstrual cycle by recording the different phases, duration, and symptoms of your cycle. Personal factors such as mood, precise temperature tracking, period flow, and symptoms can be discreetly logged on the watch or in the Withings app. This allows you to create individual routines tailored to the needs of your own body. 

Medical data at your fingertips
The Withings app is an ideal tool for tracking activity, sleep, weight, and more. The app provides overviews of history and progress and delivers valuable data that can be used daily or shared directly with a doctor.
