The world’s most advanced health wearable

  • Heart health monitoring
  • Breathing disturbances tracking
  • Sleep analysis
  • Activity tracking
  • Durable design

ScanWatch is the first hybrid smartwatch to continuously scan vital parameters to detect heart health conditions and help improve overall fitness.

Developed with professionals from world-renowned institutions, ScanWatch boasts a medical-grade ECG, an oximeter for SpO2 measures, and an exceptional battery life of up to 30 days.

The appeal should be obvious to anyone who appreciates the classic design and wants to stay on top of their heart and sleep health.


Not many true smartwatches or fitness trackers contain quite as many health-monitoring features, from general activity to comprehensive sleep tracking.


Withings has got a lot right with the ScanWatch. It is an attractive hybrid watch that blends traditional aesthetics with some of the smartest technology available on any wearable today (smartwatches included).


More than ever, we need to take responsibility for our own health and the technology ScanWatch provides allows us to do that.


The ScanWatch’s traditional clock face hides some of the most advanced tech we’ve seen in a smartwatch yet.


Heart health monitoring

Proactive heart tracking.
Invaluable peace of mind.

  • Atrial fibrillation notification
  • Proactive heart rate tracking

A notification can be sent to the user in case of a high or low resting heart rate episode.

ScanWatch can record a medical-grade electrocardiogram and detect signs of atrial fibrillation—a form of arrhythmia that can be damaging to your health if left undiagnosed. ECG readings can be easily shared with your doctor via the Withings app, providing valuable information to help them track your heart health.

How to record an ECG

To record an ECG, sit and rest, press the digital crown, scroll in the menu to find the ECG option, press again, then place your fingers on the front electrode for 30 seconds.

Withings App | Withings

Your smartphone can display the live signal during the record, and will keep all measurements to view and share at any time.

How it works

ScanWatch is equipped with three electrodes: two are on the back of the case and the other is the metal ring around the watchface.

When you place your finger on the ring, it closes a loop that allows the watch to measure your heart's electrical activity. This method is called a one-lead electrocardiogram.

Why it matters

An ECG is the best way to detect atrial fibrillation (AFib), a highly prevalent heart arrhythmia. It is a very serious condition that often goes undiagnosed because it can show no symptoms and/or not be present during doctor’s visits because the episodes can be intermittent.

In Europe, 1 out of 4 people will develop AFib.

Sleep analysis

Lie down, breathe, dream.

ScanWatch computes numerous data points to measure Sleep cycles, detect breathing disturbances and then calculates your overall Sleep Score—automatically.

Scanwatch | Withings

Sleep tracking helps you understand your night and make choices that can improve them. Our proprietary AI has been calibrated with a sleep laboratory in Manheim, Germany and with Beclere Hospital in France, using polysomnography, considered to be the gold standard for sleep analysis.

Sleep Cycles

ScanWatch tracks your sleep cycles (light and deep), duration of sleep, time to be asleep and wake up as well as interruptions, and logs it in the Withings app so you can view your trends.

Sleep Score

Our exclusive algorithm automatically scores your night based on sleep cycles, duration, regularity and interruptions.

Overnight breathing disturbances

In addition to analyzing sleep, activating the Respiratory Scan can identify breathing disturbances, and provide an analysis of continuous blood oxygen levels (SpO2), heart rate, motion and breathing rate.

Sleep heart rate

Punctual measurements of your heart rate at night will help you understand your Sleep Heart Rate, the average heart rate during sleep. It differs from Resting Heart Rate which is a single measurement, usually taken just after waking up.

Smart Wake-up

Because ScanWatch knows if you are in a light or deep stage, it can choose the best time to wake you up according to your schedule. You simply set a wake-up time in the app, and ScanWatch will wake you with a light vibration.

Workout Mode

Scanwatch | Withings

Easily activate workout mode right on your wrist by choosing from over 30 sports. This shows your workout duration, and logs heart rate and movement continuously.

Fitness level

ScanWatch assesses your Fitness Level when you run or walk based on the maximal oxygen consumption (VO2 Max) estimation.

VO2 max is defined as the maximum amount of oxygen an individual consumes over one minute during intense physical effort. The more oxygen consumed, the harder muscles can work, and therefore the higher the VO2 max level.

Durable design
