Withings ScanWatch 2 Review 2026: The Best Hybrid Smartwatch?

Are you tired of bulky smartwatches that scream “tech” on your wrist? The Withings ScanWatch 2 might be exactly what you need.

This hybrid smartwatch blends classic analog style with serious health tracking power. It offers a medical grade ECG, SpO2 monitoring, 24/7 body temperature tracking, and an incredible 30 day battery life.

But does it still hold up in 2026? With new competitors flooding the market, you might wonder if the ScanWatch 2 is still worth its $349.95 price tag.

In this detailed review, I will cover everything you need to know. You will learn about its design, health features, battery life, app experience, and more.

Key Takeaways

• The Withings ScanWatch 2 delivers medical grade health tracking in a classic analog watch design. It includes a 1 lead ECG with atrial fibrillation detection, SpO2 blood oxygen monitoring, and 24/7 body temperature measurement. These features make it one of the most health focused hybrid smartwatches available today.
• Battery life is outstanding at up to 30 days on a single charge. This far exceeds most full touchscreen smartwatches like the Apple Watch or Samsung Galaxy Watch. Even with GPS enabled during outdoor workouts, the battery lasts well over two weeks.
• The small OLED display has limits. The 0.63 inch grayscale screen shows basic data clearly. However, it cannot match the visual experience of AMOLED screens found on Garmin or Apple devices. You will rely heavily on the companion app for detailed data analysis.
• Heart rate accuracy impressed during testing. Multiple reviewers found the ScanWatch 2 performed on par with dedicated heart rate monitors from Polar and Garmin. This is rare for a watch that looks like a traditional timepiece.
• The Withings Health Mate app is free but has a premium tier. Core health data requires no subscription. The optional Withings+ plan costs $9.95 per month and adds a Health Improvement Score, guided programs, and wellness content.
• Priced at $349.95 for both 38mm and 42mm sizes, the ScanWatch 2 sits in a competitive price range. It costs less than the Apple Watch Ultra but more than budget hybrid options like the Garmin Vivomove Sport.

Withings ScanWatch 2 Design and Build Quality

The Withings ScanWatch 2 looks like a premium traditional watch. It features a stainless steel case with sapphire glass over the watch face. This combination protects the display from scratches and everyday wear.

The watch comes in two sizes. The 38mm version suits smaller wrists, while the 42mm version fits larger wrists. Both sizes cost $349.95. You can choose from several color options including silver/black, silver/white, and rose gold/blue.

Analog hands sit over a small digital OLED display at the top of the watch face. A secondary analog dial at the bottom tracks your daily step goal progress. This design keeps the watch looking classic and understated.

The fluoroelastomer band is soft and comfortable for all day wear. It does not irritate the skin during workouts or sleep. The band uses a standard buckle and is easy to swap out for third party options if you prefer a leather or metal strap.

Overall, the ScanWatch 2 weighs just 52.6 grams for the 42mm model. It sits flat on the wrist and does not feel bulky. You can wear it with a suit or gym clothes without it looking out of place.

Display and User Interface

The ScanWatch 2 uses a 0.63 inch grayscale OLED display. This screen is slightly larger than the original ScanWatch’s 0.54 inch panel. It shows health metrics, notifications, and workout data in a simple text format.

There is no touchscreen on this watch. You control everything with the side crown button. Press it to wake the screen. Turn it to scroll through menus. Press again to select an option. This system works well once you get used to it.

The small screen does have clear limits. Reading long notifications is difficult. You cannot view detailed charts or graphs on the watch itself. The display shows short text summaries of your data.

However, the grayscale OLED is easy to read outdoors. It does not wash out in direct sunlight like some color AMOLED displays. The simplicity of the interface also means less distraction during your day.

For people who want a full touchscreen smartwatch experience, this watch will feel limiting. But for those who value a clean, minimal interface, the ScanWatch 2 delivers exactly that.

Heart Health and ECG Features

The medical grade ECG is a standout feature of the ScanWatch 2. You can record a 1 lead electrocardiogram directly from your wrist in just 30 seconds. The watch detects normal sinus rhythm, atrial fibrillation, or returns an inconclusive result.

To take an ECG reading, you sit still and place your fingers on the metal bezel. The watch vibrates once to start and twice when the recording is complete. You can view the ECG tracing in the Withings Health Mate app in real time.

The ECG data is shareable with your doctor directly from the app. This makes it a practical tool for people who need to monitor their heart rhythm regularly. It is particularly useful for those with a history of AFib.

The ScanWatch 2 also tracks your resting heart rate around the clock. It provides average daily and nightly heart rate readings. You can set custom alerts for unusually high or low heart rate.

Multiple independent tests confirm that the heart rate sensor is accurate. Reviewers from PCMag and Men’s Journal found its readings matched dedicated chest strap monitors from Polar. This level of accuracy is impressive for a wrist based optical sensor.

Top 3 Alternatives for Withings ScanWatch 2

Sleep Tracking Performance

The Withings ScanWatch 2 provides detailed sleep analysis every night. It tracks your total sleep time, time spent in each sleep stage, and the number of interruptions. The watch breaks down your sleep into light, deep, and REM phases.

Sleep data syncs automatically to the Health Mate app each morning. The app presents your sleep data in clean, easy to read charts. You get a Sleep Score that summarizes your overall sleep quality on a 100 point scale.

One useful feature is the breathing disturbance detection. The ScanWatch 2 monitors your breathing patterns during sleep. It can alert you to irregularities that may indicate conditions like sleep apnea. This information can be valuable to share with a healthcare provider.

The watch is comfortable enough to wear while sleeping. It sits flat on the wrist and the lightweight design does not cause discomfort. Many users report forgetting they are wearing it at night.

Compared to dedicated sleep trackers like the Oura Ring, the ScanWatch 2 holds its own. It provides a solid overview of sleep quality without requiring a separate device on your finger.

Body Temperature and HRV Tracking

The ScanWatch 2 introduced 24/7 body temperature monitoring to the Withings lineup. This is powered by the TempTech24/7 module and HealthSense Gen 3 software. The original ScanWatch did not track temperature at all.

The watch measures your body temperature during the day and night. It establishes a personal baseline and then highlights deviations from your norm. Temperature changes can signal illness, overtraining, or hormonal shifts.

For menstrual cycle tracking, this feature is especially helpful. Temperature fluctuations can indicate ovulation and help predict cycle phases. The Health Mate app combines temperature data with logged cycle information for more accurate predictions.

Overnight HRV tracking is another major addition. Heart rate variability reflects how well your nervous system balances stress and recovery. A consistently high HRV suggests good cardiovascular fitness and recovery. A sudden drop may signal that your body needs rest.

The ScanWatch 2 records your HRV while you sleep and displays trends over time in the app. This data is valuable for athletes, fitness enthusiasts, and anyone interested in understanding their stress and recovery patterns better.

Battery Life and Charging

Battery life is one of the ScanWatch 2’s biggest strengths. Withings promises up to 30 days on a single charge with normal use. In real world testing, this claim holds up well.

Without GPS use, the watch easily lasts a full month. Even with regular GPS tracking during outdoor workouts, users report getting two to three weeks before needing to recharge. This is far ahead of most full touchscreen smartwatches.

Charging takes less than two hours from empty to full. The watch uses a proprietary magnetic charging cradle. You simply place the watch in the dock and it begins charging.

The charger itself has some downsides. It is a lightweight plastic cradle that does not grip the watch firmly. The watch can slip out if the surface is bumped. This is a minor annoyance but worth noting.

A replacement charger costs $25 from Withings if you lose or break the original. The watch does not support wireless charging standards like Qi, so you must use the Withings charger.

Overall, the battery performance is exceptional. You spend far less time charging and more time actually using the watch. This makes the ScanWatch 2 a practical choice for travelers and busy professionals.

Fitness and Workout Tracking

The ScanWatch 2 supports over 40 workout modes. These include running, cycling, swimming, hiking, and general cardio activities. You can start and stop workouts directly from the watch.

Built in GPS tracks your outdoor routes, pace, and distance. The GPS accuracy is solid based on testing. It aligns closely with readings from dedicated running watches like the Garmin Forerunner series.

During workouts, the watch displays real time heart rate, duration, and calories burned on the small OLED screen. The data is limited by the display size, but it covers the essentials.

The watch is water resistant to 5 ATM (50 meters). You can wear it while swimming in a pool or the ocean without worry. It tracks swim sessions and provides basic stroke data.

Post workout data syncs to the Health Mate app. The app shows detailed breakdowns including heart rate zones, GPS maps, pace charts, and calories. This level of detail is helpful for tracking progress over time.

The ScanWatch 2 does not offer advanced running metrics like cadence or ground contact time. Serious runners may want a dedicated GPS running watch for that level of detail. But for general fitness tracking, it performs very well.

Withings Health Mate App Experience

The Withings Health Mate app is available for both iOS and Android. It serves as the central hub for all your health data from the ScanWatch 2. Setup takes just a few minutes through Bluetooth pairing.

The free version of the app provides access to all core health metrics. This includes heart rate data, ECG recordings, sleep analysis, step counts, body temperature trends, and workout summaries. You do not need a subscription to use the watch effectively.

The optional Withings+ subscription adds extra features. These include a Health Improvement Score, personalized health guidance, workout videos, and recipes. It costs $9.95 per month or $99.50 per year.

The app interface is clean and well organized. Data is presented in clear graphs and charts. You can view trends over days, weeks, or months. The dashboard gives you a quick snapshot of your daily health status.

One strong point is the app’s ability to integrate with other health platforms. Health Mate works with Apple Health, Google Fit, and Strava. This means your ScanWatch 2 data flows into your broader fitness ecosystem.

The app also supports multiple Withings devices. If you own a Withings smart scale or blood pressure monitor, all data consolidates in one place. This makes Health Mate a powerful personal health dashboard.

Withings ScanWatch 2 vs Apple Watch

This is a common comparison, and the answer depends on your priorities. The Apple Watch offers a full color touchscreen, a massive app ecosystem, phone call support, and cellular connectivity. It does far more as a smartwatch.

The ScanWatch 2 takes a different approach. It focuses on health monitoring in a traditional watch body. It does not run apps, take calls, or display rich media. What it does, it does quietly and elegantly.

Battery life is the biggest difference. The Apple Watch lasts about 18 to 36 hours depending on the model. The ScanWatch 2 lasts up to 30 days. This is a huge advantage for people who do not want to charge their watch every night.

For ECG and heart health monitoring, both watches perform well. The Apple Watch offers irregular rhythm notifications and ECG recording. The ScanWatch 2 matches these features and adds continuous temperature tracking.

If you want a smartwatch that replaces your phone on your wrist, choose the Apple Watch. If you want a health tracker that looks like a real watch and lasts for weeks, the ScanWatch 2 is the better choice.

Who Should Buy the Withings ScanWatch 2?

The ScanWatch 2 is a great fit for several types of buyers. Health conscious professionals who want discreet health tracking will love it. It looks appropriate in business settings where a bulky smartwatch might not.

People who value long battery life above all else should consider this watch. Charging once a month is a real luxury compared to daily charging routines required by most smartwatches.

Anyone interested in heart health monitoring will benefit from the ECG, heart rate tracking, and HRV features. These tools provide meaningful data you can share with your doctor during checkups.

The ScanWatch 2 also suits travelers and minimalists. You do not need to bring a charger on short trips. The clean, classic design works across all situations from hiking trails to formal dinners.

However, this watch is not for everyone. Fitness enthusiasts who need advanced running metrics should look elsewhere. People who want app notifications, music control, and smart assistant access will find the ScanWatch 2 too limited.

If you want the perfect blend of health tracking and traditional watch design, the Withings ScanWatch 2 remains an excellent choice in 2026.

Withings ScanWatch 2 Pros and Cons

Every product has strengths and weaknesses. Here is an honest look at where the ScanWatch 2 excels and where it falls short.

The pros are significant. The 30 day battery life is class leading. The medical grade ECG and SpO2 sensors provide real clinical value. The 24/7 temperature tracking adds useful recovery and cycle insights. The stainless steel and sapphire glass build feels premium. It looks like a real watch, not a gadget.

The cons are worth noting too. The 0.63 inch grayscale OLED is small and limits what you can see at a glance. There is no touchscreen. Notifications are basic and hard to read. The proprietary charger is flimsy and the watch can slip out of the dock.

The $349.95 price is fair for what you get, but competitors offer more screen real estate and smart features for similar money. The optional Withings+ subscription adds cost if you want premium health insights.

The ScanWatch 2 makes deliberate trade offs. It sacrifices smart features and screen size for battery life and elegant design. Whether those trade offs work for you depends on what you value most in a wearable.

Final Verdict on the Withings ScanWatch 2

The Withings ScanWatch 2 remains one of the best hybrid smartwatches you can buy in 2026. It excels at health tracking while maintaining a timeless analog appearance. The combination of ECG, SpO2, body temperature, HRV, and sleep tracking is hard to beat in a hybrid form factor.

Battery life alone makes it stand out. Going 30 days between charges removes a major pain point of modern smartwatches. The accurate heart rate sensor and medical grade ECG add genuine health value.

The watch is not perfect. The small screen, lack of touch input, and basic notification support are real limitations. If you need a full featured smartwatch, this is not the right pick.

But if you want a health focused wearable that looks like a luxury timepiece, the ScanWatch 2 delivers. It is a thoughtful product for people who care about their health and their style. At $349.95, it offers solid value for the features it includes.

I recommend the Withings ScanWatch 2 for anyone who wants serious health insights without sacrificing classic watch aesthetics. It has earned its place as a top hybrid smartwatch heading into 2026 and beyond.
