Your 24/7 health tracker

ScanWatch 2 monitors important health metrics whenever it's on your wrist and syncs the information automatically to the Withings app on your phone (compatible with iOS and Android devices). The accurate wrist-based sensor records your heart rate and blood oxygen level, plus keeps an eye out for irregular heartbeats, while an advanced heat-flux sensor tracks your body temperature day and night. These readings can help you monitor your performance as the weather changes, and even help identify the onset of an illness.

ScanWatch 2 also provides some awesome tools to let you know just how well you're sleeping at night. It monitors your movement, heart rate, and more to measure and record your sleep cycles. It also tracks respiration to detect breathing disturbances. In the morning, you'll have a Sleep Score to let you know just how rested you are.

Withings SmartScan 2

SmartScan 2 uploads information automatically to the Withings Health Mate app.

Health Mate pairs with your phone for fitness activities

When you're ready for a run, swim, or walk around the block, ScanWatch 2 automatically detects activity and logs it in the Withing Health Mate app on your smartphone. Health Mate also tracks distance using your phone's GPS. And if you're a step counter, you'll be happy to know that this versatile watch automatically tracks your daily steps. ScanWatch 2 is compatible with other popular fitness apps, too.

Classic style, cutting-edge tech

ScanWatch 2 isn't just a pretty face. It's built tough, with a 5 ATM waterproof rating, a stainless steel case, and a scratch-resistant sapphire glass lens. And with 30 days of battery life, it'll spend more time on your wrist and less on the charger.

For different looks, change the bands to match the occasion. ScanWatch is compatible with 18 mm (38 mm watch models) and 20 mm (42 mm watch models) bands.

Product Research


Overview: The Withings ScanWatch 2 (HWA10) is a clinically validated health and fitness watch that helps you monitor several health parameters and even detect serious issues. The hybrid smartwatch was designed in France, and developed with professionals from world-renowed institutions to promote a healthy lifestyle. It is equipped with a heart rate monitor and ECG, connected GPS, activity tracking, and sleep analysis. All of your activity and health data can be viewed on your smartphone or tablet via the Withings Health Mate app. ScanWatch 2 has a stylish analog watch face with a separate activity dial, plus a small circular digital screen for customized notifications. The device has a long-life rechargeable battery, with a 30 day battery life between charges (normal use). The Withings ScanWatch 2 is covered by a 2-year warranty.

Design: ScanWatch 2 has a Stainless Steel case (38mm) with an anti-reflective Sapphire Glass crystal, which is tough and scratch-resistant. The 18mm black fluoroelastomer wrist band is soft, durable, and water-resistant, and fits wrists up to 7.79" in circumference. Withings offers optional interchangeable 18mm wrist bands in multiple colors and materials. The ScanWatch 2 is water resistant with a 5 ATM rating, capable of withstanding pressures equivalent to a depth of 50 meters (165 feet). You can wear the watch in rain or snow, or while showering.

Note: The ScanWatch 2 is also available with a larger, 42mm case.

Battery: ScanWatch 2 is equipped with an efficient Lithium-ion rechargeable battery that lasts up to 30 days under normal use. The watch comes with a charging dock that clips to the back of the case and aligns with the charging pins. Charging time is approximately 2 hours to reach 100% battery capacity.

Subdial: The small subdial at the bottom of the watch face is a round meter that expresses your progress toward your daily activity goal as a percentage. The subdial looks like a separate second hand, however, it has 50 markings to show your progress toward your step goal. Each mark denotes 2% toward your goal and a complete revolution indicates reaching 100% of your goal.

OLED Display: ScanWatch 2's 0.63" diameter grayscale OLED display features numerous screens to keep you informed of your activity and health data. You can view your heart rate, ECG, SpO2, number of daily steps, distance traveled, and calories burned. As a stopwatch, you can time your workout or activity. You can also view the battery level, and the time of your next alarm. When ScanWatch 2 is paired with your smartphone, you can receive notifications from your calendar, email, texts, and phone calls. To select the display mode you desire, simply turn the crown on the side of the watch and press it when your selection appears.

Health Metrics: Using the ScanWatch 2's built-in health sensors, you can measure and analyze many aspects of your health and fitness. Pairing the watch with the Withings Health Mate app lets you record, store, analyze, and share your vitals with others, including your doctor.

Temperature Sensor: ScanWatch 2 is equipped with a new temperature sensor on the back of the watch that constantly measures your body temperature and establishes a baseline of your day and night temperatures. The TempTech24/7 module tracks your body temperature fluctuations, which may indicate the onset of an illness or other health condition. As you workout, it also helps you manage your performance and recovery by using temperature variation zones, as well as helps you to avoid heat exhaustion.

Heart Rate: The heart rate sensors on the back of the watch case use photoplethysmography (PPG), which uses green LED light to detect variation in the level of blood in the wrist to determine the heart rate. The device takes a heart rate measurement every ten minutes or so, allowing you to see how the rate fluctuates during the day. ScanWatch 2 can detect a resting heart rate that is high or low, compared to your usual heart rate, and send you a notification. During Workout Mode, the watch monitors your heart rate continuously. The watch and Health Mate app can detect an irregular rhythm and send a notification through your smartphone.

SpO2: The watch uses a clinically-validated SpO2 sensor, with exclusive multi-wavelength technology, to measure and record your blood oxygen levels from your wrist. SpO2 levels are expressed as a percentage, with the normal range between 90 and 100%. Wearing ScanWatch 2 while you sleep can help detect breathing disturbances, such as sleep apnea, that cause your oxygen saturation levels to plummet.

ECG: ScanWatch 2 can produce a clinically-validated electrocardiogram (ECG) in 30 seconds. The ECG can possibly detect and warn you of a serious condition called AFib (atrial fibrillation), a prevalent heart arrhythmia. Placing your hand on the stainless steel watch case creates a closed electrical circuit, enabling the watch to measure your heart's electrical activity. You can see the results immediately on the watch screen, or view a more in-depth diagnostic report in the Health Mate app. In addition, the results can be easily shared with your doctor via the app.

Sleep Tracking: ScanWatch 2 monitors several data points while you sleep to give you an overall sleep quality score between 0 and 100. Using polysomnography, the watch measures your heart rate, blood oxygen levels, breathing disturbances, body movement, duration and levels of your sleep, and number of interruptions to calculate your sleep score. You can set an alarm in the Health Mate app to gently awake you with silent vibrations based on your current sleep level.

Walking and Running: ScanWatch 2 has a precision 3-axis accelerometer that can detect the direction and intensity of your movement to identify (and track) your activity. The watch measures the number of steps you take daily, the distances you travel, and the calories burned, based on your user profile (height/weight entered during setup). If you walk stairs, the connected GPS (from your paired smartphone) measures your elevation to determine the number of floors climbed.

Workout Mode: During Workout Mode, the watch uses the GPS in your phone (Connected GPS) to track your running/walking route on a map. While you work out, your heart rate is continuously monitored to show your VO2 Max (oxygen consumption), fitness level, and recovery. ScanWatch 2 is also compatible with third party apps, including Strava, for uploading your workout results. There are over 30 sports to choose from, including swimming, running, walking, and biking.

Menstrual Health: ScanWatch 2 can be a valuable tool to track the menstrual cycle. Logging and tracking your symptoms, phases, and length of your menstrual cycle from month-to-month can help you analyze your unique cycle patterns. Monitoring your period helps you detect changes that may be linked to other health issues. Your menstrual health data can be combined into a comprehensive report that can be shared as a PDF with your doctor.

Withings Health Mate: ScanWatch 2 connects wirelessly via Bluetooth Low Energy (BLE) to your smartphone or tablet and the Withings Health Mate app. The app pulls data from the ScanWatch 2 and other connected Withings health devices, including the temporal thermometer, sleep monitor, and smart scales. Using the app, you can track your weight, physical activity, heart rate and cardiac health, sleep, and other health metrics. The app can also notify you of possible chronic conditions when the data shows potential for concern. The Withings Health Mate app is compatible with iPhone and iPad running iOS 15.0 or later. The app is also available for Android devices running version 9.0 and up.

Other Apps: The Withings ScanWatch 2 is compatible with many other health and fitness devices and apps, including Apple Watch, Apple Health app, Google Health Connect, and Google Fit.
