Withings Scanwatch Nova – Your Health Scan Companion in 2025

When I first heard about the Withings Scanwatch Nova, I was curious about how a watch could do more than just tell the time. Over the years, wearable technology has evolved to become a personal health assistant on your wrist. In 2025, the Withings Scanwatch Nova stands out as a powerful tool that helps you understand your body like never before.

It is more than a smartwatch. It is a complete health monitoring device designed for people who care about their well-being. Let’s get deep into everything this impressive piece of technology has to offer, as I have created this blog post on Withings Scanwatch Nova features, specs, and health monitoring capabilities.

The Withings Scanwatch Nova is a hybrid smartwatch designed to combine classic watch style with advanced, medically accurate health tracking.

It looks like a traditional analog watch but has built-in digital features and sensors that can:

• Record an ECG (electrocardiogram) to detect irregular heart rhythms like atrial fibrillation
• Measure blood oxygen levels (SpO2) for respiratory health monitoring
• Track sleep stages and detect breathing disturbances
• Monitor daily activity like steps, distance, and calories burned
• Support workout tracking for different sports
• Offer up to 30 days of battery life on a single charge

The Scanwatch is FDA-cleared for its ECG and SpO2 functions, which makes it more medically reliable than most wearable fitness gadgets. It is designed for people who want both a stylish wristwatch and a serious health monitoring device they can wear all day, every day.

The Withings Scanwatch Nova has gained attention for being one of the most health-focused smartwatches available today. Unlike many other wearables that prioritize notifications and apps, this watch is built to help you keep track of your body’s vital signs.

It is packed with advanced health sensors, a sleek design, and features that make it suitable for both everyday wear and intense health monitoring.

Now, here is where the Withings Scanwatch Nova truly shines. It is not just about counting how many steps I take in a day. It is about giving me real, medically accurate insights into what’s going on inside my body.

The watch is packed with sensors that work quietly in the background, similar to the Samsung Galaxy Watch 6 Classic. However, when it comes to health tracking, it gathers data more effectively that can help you make better decisions about your lifestyle, fitness, and overall well-being. Unlike many other smartwatches that provide general wellness estimates, the Withings Scanwatch Nova aims for precision.

It often uses medical-grade technology that has been clinically validated. That’s the reason I see it not just as a gadget but as a personal health assistant that I can carry on my wrist every single day.

So, what are the key health monitoring capabilities of Withings Scanwatch Nova? Let’s have a look at what I have listed and explained.

1. ECG and Heart Health Tracking

One of the most impressive features of the Withings Scanwatch Nova is its ECG (electrocardiogram) function. Instead of waiting for a doctor’s appointment, you can run an ECG in just 30 seconds, right from my wrist. 

All you have to do is open the ECG mode, place your fingers on the bezel, and the watch records the electrical activity of your heart. The results are displayed instantly on the watch and stored in the Health Mate app.

If the watch detects an irregular rhythm such as atrial fibrillation, you can export the report as a PDF and share it with your doctor immediately. It is a massive advantage for people at risk of heart conditions, as early detection can be life-saving.

For me, the peace of mind alone makes this feature worth it.

2. Blood Oxygen Measurement

The Scanwatch is also equipped with a reliable SpO2 sensor that measures the oxygen saturation level in my blood. Oxygen saturation is a critical health indicator, especially if I am monitoring respiratory issues, altitude adaptation, or my recovery after exercise.

This feature is incredibly helpful during workouts, long hikes, or even while sleeping, as it can reveal if your oxygen levels drop unexpectedly. In 2025, having this kind of continuous monitoring is not just a fitness perk. In fact, it is an important health safeguard.

The readings are quick, easy to understand, and stored for long-term tracking, which makes it simple to see patterns over weeks or months.

3. Sleep Analysis

I have always believed that the quality of my day depends on the quality of my sleep. The Scanwatch takes sleep tracking to a more advanced level. It does not just tell you how long you slept. Instead, it breaks it down into light, deep, and REM stages. It also tracks interruptions and movement throughout the night, a feature that is not mighty effective in many Apple watches.

One of the most valuable insights it provides is the sleep score, which is based on duration, depth, regularity, and interruptions. I have used this feature to pinpoint habits that disrupt my rest, like late-night coffee or inconsistent bedtime schedules.

What sets it apart is the inclusion of respiratory tracking, which can flag potential breathing issues that might be affecting your rest without you realizing it.

4. Respiratory Health Insights

It is one of the lesser-known but most important features of the Withings Scanwatch Nova. While you sleep, the watch continuously monitors your breathing pattern. If there are frequent pauses or disturbances, it can indicate potential conditions such as sleep apnea.

Sleep apnea often goes undiagnosed because people are not aware they have it. After all, they are asleep when it happens. But its effects are serious, from constant fatigue to cardiovascular problems. Having a device that can detect the warning signs is a game changer.

Even if it can’t replace a full sleep study in a clinic, it provides an early alert so you can take action sooner rather than later.

In the under section, I have mentioned the key features of the Withings Scanwatch Nova that will make you understand why this tech gadget is getting so much popularity.

1. Design and Build Quality

I believe that a health watch should be comfortable enough to wear every day, and the Withings Scanwatch Nova truly delivers here. It blends premium materials with a timeless watch design, which means you do not have to compromise style for health tracking.

• Premium Materials: The watch uses stainless steel for durability, along with scratch-resistant sapphire glass. This combination ensures it looks elegant while also surviving daily wear and tear.
• Comfort and Fit: The adjustable straps make it suitable for all wrist sizes. I have worn it for long periods without feeling irritation, which is essential if you want to track health data continuously.

2. Display and Interface Experience

A health watch should be easy to read in any lighting condition, and the Withings Scanwatch Nova nails that aspect.

• Hybrid Display: It offers a hybrid display with analog hands and a small digital screen. The analog design gives it a traditional look, while the screen lets you view essential health metrics instantly.
• Navigation Simplicity: You can navigate through menus with a rotating crown, like the one present in Apple Watch Series 5 and Apple Watch Series 7, which feels more natural than tapping endlessly on a small touchscreen.

3. Fitness and Activity Tracking

While it focuses on health, the Withings Scanwatch Nova does not neglect fitness tracking. And that’s the most convincing point for which I am a big fan of this health monitoring gadget.

• Daily Activity Goals: The watch helps you stay active by setting personalized daily goals for steps, calories burned, and movement.
• Workout Modes: It includes multiple workout modes, whether you are running, cycling, or doing yoga. These modes help track performance metrics accurately.
• GPS Connectivity: Although it relies on connected GPS from your phone, it still delivers precise distance and pace data for outdoor activities.

4. Battery Life and Charging Experience

If there is one thing I appreciate about the Scanwatch, it is the battery life. Unlike other smartwatches that need daily charging, this one keeps going for weeks.

• Long-Lasting Power: It can last up to 30 days on a single charge, depending on usage. I remember when I traveled with this watch without even packing a charger.
• Easy Charging: It uses a magnetic charging dock, which is both convenient and quick.

5. Accuracy and Reliability of Data

A health watch is only as good as the accuracy of its data. Although it is true that not all the devices offer precise information, there is no such issue with the Withings Scanwatch Nova. The reasons are:

• Medical-Grade Sensors: The Scanwatch is FDA-cleared for ECG and SpO2 measurements. As a result, the readings meet strict accuracy standards.
• Data Integration: It syncs with the Withings Health Mate app, which provides easy-to-read reports and trends over time.

While its core focus is health, the Withings Scanwatch Nova still offers useful smart features. Thus, you can also wear it with your blazer or casual dresses as well to look more elegant and classy. The other features of Withings Scanwatch Nova beyond health tracking are:

• Notifications: You can receive call, text, and app notifications directly on the watch, which allows you to stay connected without pulling out your smartphones.
• Water Resistance: It is water resistant up to 50 meters, so you can swim or shower without worrying about damage.

When comparing it with devices like the Apple Watch Series 7 or Samsung Galaxy Watch 6 Classic, the Scanwatch stands out for its battery life and medical-grade sensors. While others may have more apps, few match its blend of style, durability, and health focus.

So, the next query is who should buy the Withings Scanwatch Nova? From my experience, it is ideal for:

• People who want reliable health data without charging daily
• Users with specific heart or respiratory monitoring needs
• Those who prefer a classic watch look with smart capabilities

As of this year, the Withings Scanwatch Nova is priced competitively considering its advanced health features. It is widely available online and through major electronics retailers.

On the official site, the Withings Scanwatch Nova pricing is $599.95. Now, it is up to you to determine your budget to make an informed decision whether it can be a suitable pick for you.

After using the Withings Scanwatch Nova extensively, I can confidently say it is one of the best health-focused wearables you can buy in 2025. It combines premium design, reliable health data, and unmatched battery life.

While it may not have as many third-party apps as some competitors, its focus on your well-being makes it worth considering if health is your priority.

The Withings Scanwatch Nova in 2025 is not just another smartwatch. It is a health companion that stays on your wrist day and night, providing valuable insights into your heart, sleep, and activity levels.

I have found it reliable, comfortable, and incredibly easy to use. Whether you are a health-conscious individual or someone who wants to monitor specific conditions, this watch is worth every penny.
