Heart Health Monitoring
Record an ECG at any time thanks to a mirror-polished serrated bezel that acts as an electrode.
Optical heart rate sensor
The optical sensor keeps tabs on heart rate consistently, while also conserving battery life by activating periodically around the clock. A notification can be sent to the user in the case of a high or low resting heart rate episode. Continuous heart rate monitoring is activated and recorded when using Workout Mode.
Proactive rhythm monitoring
ScanWatch monitors heartbeat automatically so it can send notifications if irregular rhythms are detected it will then advise the wearer to record an electrocardiogram (ECG).
Medical-grade SpO2
To deliver the percentage of blood oxygen, or SpO2, ScanWatch uses a multi-wavelength PPG sensor to emit and measure red and infrared reflections of blood vessels in the wrist. Normal SpO2 values vary between 90 and 100%, and readings appear on the watch and in the app.
ECG readings
An ECG is the best way to detect atrial fibrillation (AFib), a highly prevalent heart arrhythmia. AFib often goes undiagnosed because it can show no symptoms and/or not be present during doctor’s visits because the episodes can be intermittent.
Share with a doctor
All heart health data is compiled in the app and can be easily shared with a doctor, health coach, or loved one with a few taps via the Health Report feature.

Reviews
Convinced me I no longer need a luxury watch. Feels premium, and has the health benefits of a smartwatch. I like to track my steps and heart rate throughout my day. Also ensures I never miss a call which I tend to do without. I do have an issue that my watch minute hands do not line up perfectly. But that’s a nitpick.

Best choice if you wish advanced digital features in classic watch body. No more need to choose between classic stylish watch and modern digital wearables.

I have atrial fibrillation treated via catheter ablation that occasional goes awol. I was looking for a wearable device that will track my AF, and enable me to record an ECG of any AF events for my heart specialist. The Withings Scanwatch Horizon goes beyond what I was looking for but in the end, it just looks like a watch! Battery life is way off the scale when you compare it to other similar devices on the market. Paired with the Health Mate app it gives me precise details on whats going on with my general health so I can evaluate my heart health and possibly tweak my lifestyle here and there and keep my AF at a controllable level.
