Withings ScanWatch 2 Review: Classic Looks, Modern Health Tracking

You are currently viewing Withings ScanWatch 2 Review: Classic Looks, Modern Health Tracking


Withings ScanWatch 2 straddles the line between classic analog watches and modern smartwatches. It boasts a sleek, traditional design with subtle tech integration, offering a compelling option for those seeking a balance between style and health tracking. But is it the perfect blend of fashion and function, or does it fall short on either side? This in-depth review dives into the ScanWatch 2’s design, features, performance, and health tracking capabilities to help you decide.

Classic Design with a Modern Edge

The Withings ScanWatch 2 makes a strong first impression. It comes in two sizes (38mm and 42mm) with a variety of watch face and strap options. We tested the 42mm version with a black dial and a comfortable silicone strap. The brushed stainless-steel case feels premium and exudes timeless elegance. The sapphire crystal adds a touch of luxury and provides excellent scratch resistance—a welcome feature for everyday wear.

While undeniably handsome, the ScanWatch 2 isn’t the slimmest smartwatch on the market. The included silicone strap is comfortable, but some users might prefer a dressier leather option for a more formal look. Withings offers additional straps for purchase, allowing for some customization.

One of the key design elements that sets the ScanWatch 2 apart is its lack of a touchscreen display. Instead, it relies on physical hands and sub-dials for timekeeping and basic information display. Tucked beneath the main watch face is a small digital display that shows notifications, sleep data, and other health metrics. While some might miss the convenience of a touchscreen, the analog approach contributes to the watch’s classic aesthetic and exceptional battery life.

Health Tracking Features Galore

Withings packs a significant amount of health tracking tech into the ScanWatch 2. The highlight is the built-in ECG (electrocardiogram) app, which allows you to capture a medical-grade heart rhythm reading in 30 seconds. This feature has FDA clearance in the US and CE marking in Europe, offering a level of accuracy and reliability uncommon in consumer wearables.

Beyond ECG, ScanWatch 2 tracks an array of other health metrics, including:

  • Blood Oxygen Saturation (SpO2): Monitors oxygen levels in your blood, potentially indicating sleep apnea or respiratory issues.
  • Sleep Tracking: Analyzes your sleep patterns, including sleep stages (light, deep, REM) and sleep disturbances.
  • Activity Tracking: It counts steps, distance, calories burned, and various workout activities.
  • Body Temperature: Monitors your body temperature fluctuations, which can be helpful in identifying potential illnesses.
  • Breathing Rate: Tracks your respiration rate, which can be a valuable indicator of overall health and fitness.

Performance and User Experience

Withings ScanWatch 2 delivers accurate and reliable health data in most cases. The ECG app is particularly impressive, offering a convenient way to monitor heart rhythm for potential irregularities. Sleep tracking is also detailed, providing insights into sleep quality and potential areas for improvement.

However, the Withings Health Mate app, which stores and displays all your health data, can be a bit of a mixed bag. While the app is generally easy to navigate, the data presentation can feel cluttered at times. Additionally, some advanced features, such as detailed sleep analysis and personalized coaching, are locked behind a Withings+ paywall. This can be frustrating for users who might expect these features to be included in the base price of the watch.

Battery Life: A Champion for Long Wear

One of the biggest advantages of the ScanWatch 2 is its exceptional battery life. Withings claims the watch can last for up to 30 days on a single charge, although this depends on usage patterns. With features like continuous SpO2 monitoring or frequent notifications enabled, you can expect a slightly shorter lifespan. Regardless, even with moderate usage, the ScanWatch 2 easily lasts a week or two between charges, a stark contrast to the daily charging routines required by many smartwatches.

Charging is simple and straightforward using the included magnetic charging cradle. A full charge takes around two hours, which is a reasonable timeframe considering the extended battery life.

Who Should Consider the Withings ScanWatch 2?

The Withings ScanWatch 2 is a stylish and functional hybrid smartwatch ideal for users who prioritize:

  • Classic Design: Those who appreciate the look and feel of a traditional watch will find the ScanWatch 2 a refreshing alternative to bulkier smartwatches.
  • Advanced Health Tracking: With features like ECG and SpO2 monitoring, the ScanWatch 2 is well-suited for users who want a deeper understanding of their health.
  • Long Battery Life: With weeks of battery life on a single charge, the ScanWatch 2 is perfect for those who don’t want to be tethered to a charger every night.

  • Classic, elegant design
  • Excellent build quality
  • Unmatched battery life (up to 30 days)
  • FDA-approved ECG app
  • wide range of health tracking features

Final Verdict

The Withings ScanWatch 2 is a unique offering in the smartwatch market. It blends classic design with cutting-edge health tracking technology, making it a great option for those who value both style and functionality. While the app could be improved and smartwatch features are limited, the long battery life and impressive health suite make the ScanWatch 2 a compelling choice for health-conscious individuals who appreciate a timeless aesthetic.
