Withings ScanWatch 2 review: Should you buy it?

Update, October 2024: This review has been updated to account for new alternatives available within the market, including upgraded devices from Apple, Google, and Samsung.

Should you buy the Withings ScanWatch 2?

It’s the nature of my job to always be sporting one, if not two, overtly techy wearables, typically with colorful, AMOLED displays and gym rat aesthetics. This is fantastic for someone who keeps up with modern gadgetry, works out regularly, and can probably do a handful of pull-ups (spoiler, I cannot), but what about anyone looking to venture out of the house without broadcasting that they religiously track steps? The Withings ScanWatch 2 is just the answer. Its elegant, analog design suggests a cocktail bar more than a curl bar, yet it quietly tracks a handful of advanced health stats and activity data like any modern smartwatch.

At first glance, the ScanWatch 2 is simply a stylish timepiece and a gorgeous one at that. With clean lines and premium build materials, the watch seamlessly blends into a business casual wardrobe (though it doesn’t look out of place with jeans and a t-shirt either). Its stainless steel case features a protruding rotating crown and is available in either 42mm or 38mm, each offering a small range of color options. In the larger size, shoppers will find black or pearl white choices. In 38mm, the options expand to include sand or blue faces with gold cases. Covered in sapphire glass, each display features a standard clock face plus a secondary dial for tracking your step goal.

And then things start to get interesting. Like the original ScanWatch, the newer generation features a small grayscale OLED display, the official “window” into the watch’s undercover features. With a turn of the digital crown, users can check their heart rate, temperature variation, steps, and distance, start a workout or breathwork session, take an ECG or SpO2 measurement, and access the device’s settings. Notably, there isn’t a screen for sleep tracking, which feels like a slight oversight as the ScanWatch 2 can actually track your sleep patterns, which I’ll cover more below. This display space is small, measuring just .63 inches, but I find it plenty useful for completing basic tasks and checking stats.

Fortunately, the device records a ton of key stats worth checking. Like the original, the ScanWatch 2 tracks steps, distance, calories, workouts, heart rate, and blood oxygen. As mentioned, it also offers on-demand SpO2 readings as well as on-demand ECG recordings with FDA-approved atrial fibrillation detection. The latter makes the watch a particularly strong contender for shoppers antsy to keep tabs on their heart health. Thanks to its timeless look, it’s a great pick for senior users who may be reluctant to wear a modern smartwatch.

As mentioned, the device is also a detailed sleep tracker, measuring sleep stages, duration, interruptions, and regularity. I found these sleep stats comparable to my Oura Ring 3; however, occasionally, the watch overestimates my sleep, counting time in bed as time asleep. (Granted, I should have been sleeping rather than reading until all hours of the night.) Unlike the original model, the 2’s PPG sensor now measures your respiratory rate.

The Withings ScanWatch 2 also adds a temperature sensor for measuring fluctuations daily and overnight, as well as during workouts. The TempTech24/7 module monitors skin and ambient temperatures to distinguish potential symptoms from environmental conditions. I didn’t receive any elevated temperatures during my testing, but theoretically, the tool could be useful for determining oncoming illness. Temperature sensing is a growing trend in the wearables market, and such trackers can now be found on most of the top devices. Adding this capability was an important upgrade for the company to keep up with the competition.

Likewise, the newer model also adds on-device women’s cycle tracking. This includes period predictions on the wrist plus the ability to log flow trends and symptoms. You can still do much more from the app than on the watch itself, but it is nice to see this access available. I am always grateful for the prioritizing of women’s health tracking, and it’s not a surprise to see a health-focused brand do so.

And yet, as mentioned at the start, this is a health-monitoring hybrid device, not a dedicated fitness tracker. Though I found the ScanWatch 2 extremely comfortable for all-day wear and sleep tracking, it isn’t meant for fitness buffs. It doesn’t pack some crucial tools for athletes, namely built-in GPS. At this point in a review, I would typically include a mapped outdoor workout to show the accuracy of a wearable’s GPS, but in this case, the data collected simply relies on your paired phone, not the watch itself.

I don’t love pocketing a phone on long runs, so the lack of built-in GPS is disappointing at this price point. However, the decision directs my attention back to the device’s intended audience. With over 40 sports modes and useful activity analysis, the ScanWatch 2 is certainly a reliable activity tracker for those interested in the basics, but it’s not a sports watch for serious athletes.

It’s also very limited in smart features, offering just band-style notifications that can be cumbersome to read. I usually don’t wait for the entire message but merely use the alert to determine whether I need to grab my phone. I would have liked to see Withings add music controls and digital payment support to the newest generation. I don’t mind the lack of apps and phone call support because, in my opinion, those features are beyond the scope of what a hybrid device needs to offer. If you find them important, this is not the watch for you.

Before you bail on the idea of a ScanWatch 2, I saved the discussion of the best feature for last. The watch can last up to 30 days between charges, a staggering stat compared to most leading smartwatches. During this review, the device easily surpassed two full weeks with regular workouts, notifications, and feature use (I’ve yet to kill the battery). Granted, I did disable Raise to Wake after the first day, as that feature will definitely drain power quickly.  However, and I cannot stress this enough, there is no feeling of luxury I appreciate more than having no idea where a device’s charger is because it rarely needs it. This is an exaggeration, I’m terribly anal about organization, but the point is, you will rarely need to charge your watch and are very unlikely to find yourself with a dead device unexpectedly.

When you do need to power up, the ScanWatch 2 ships with a proprietary charger that reminds me of child-proofing devices. You need to ensure the watch is placed in the correct orientation, then pull on the spring-loaded end to fit the watch in place. It’s straightforward despite its funky shape and securely holds the watch for effective charging. Reloading from 0 to 100% battery will take about 2 hours, which is long, but again, you won’t need to do it often.

What are the best Withings ScanWatch 2 alternatives?

The ScanWatch 2 is an attractive buy, but it’s not the only device worth considering. Check out these alternatives for more options.

• Withings ScanWatch Light (€249.95 at Withings): If you’re interested in the ScanWatch 2’s overall package but don’t need all the device’s advanced sensors, the ScanWatch Lite is a fantastic pared down option for budget-conscious shoppers. Just be aware that you won’t find temperature tracking, ECG readings, or SpO2 monitoring on board.
• Withings ScanWatch Nova ($599.99 at Amazon): At the other end of the spectrum, the pricey ScanWatch Nova packs everything you’d find on the ScanWatch 2 into an even more premium build inspired by luxury dive watches.
• Garmin Vivomove Sport ($179 at Amazon): One of Garmin’s top hybrid watches, the Vivomove Sport features useful training tools and an attractive aesthetic. We love the sleek “hidden” display that disappears when not in use.
• Apple Watch Series 10 ($386 at Amazon): Of course, no hybrid options can compete with a dedicated smartwatch when it comes to integration, apps, and display. The best smartwatch for iPhone users is the Apple Watch Series 10, which packs considerable health and fitness tracking tools. Unfortunately, the device only offers 24 hours of battery life between charges and isn’t compatible with Android phones.
• Google Pixel Watch 3 ($349.99 at Amazon): The best Wear OS device available is Google’s third-generation Pixel Watch. Not only does it boast the best Wear OS software, but it also offers unique Fitbit integration and a truly refined minimalist aesthetic.
• Samsung Galaxy Watch 7 ($299.99 at Amazon): For Samsung phone users, the best Wear OS pick is the newest generation Galaxy Watch 7. The device offers a full gamut of tools and features and packs a rotating bezel for smooth device navigation. For a more traditional aesthetics, shoppers may also consider the Galaxy Watch 6 Classic ($429 at Amazon).
