My favorite hybrid smartwatch has incredible battery life and a gorgeous look

ZDNET’s key takeaways

• The Withings ScanWatch 2 is available now for $349 in two sizes and various colors.
• The wearable is well-designed and much thinner than a standard smartwatch. It has analog hands to show the time, a robust feature set for health tracking, and a battery that lasts a full month.
• The usual drawbacks of a hybrid smartwatch include the lack of detailed graphics, no GPS tracking, and limited interactions with incoming notifications.

How often do you charge your smartwatch? Once or twice every day? Too often? Doing so regularly often makes me wonder exactly how much value I’m getting out of those occasional notifications and alerts, and it’s a big reason why I still have an affection for hybrid smartwatches.

One of these is the first Withings ScanWatch, released in 2021. I’ve worn it regularly over the past couple of years, primarily because it feels fantastic on the wrist while capturing key health data. Each charge can last up to one month. 

At first glance, the newer ScanWatch 2<!–> is tough to distinguish from the original, but it packs a few important upgrades that make one of my go-to health trackers even better.

I tested the ScanWatch 2 in Black (pictured below), but it is also available in Pearl White for the larger size. The Black model has hands that feature a Super LumiNova coating so they glow in the dark for a short time after exposure to light. If you prefer a smaller 38mm size, that’s available in Pearl White, Black, Sand, and Blue. Interestingly, both sizes cost $349, so you don’t need to pay more for a larger watch face, which is nice.

The 42mm ScanWatch 2 I’ve been wearing weighs about 52 grams and fits gently on the wrist. As much as I’ve enjoyed the watch’s health-tracking capabilities, the look and feel of the ScanWatch on my wrist are easily one of my favorite features.

A domed sapphire glass covers the analog watch hands and internal OLED display. When paired with the stainless steel case and rotating crown button, the watch screams elegance. So avoid this if you prefer rugged, multi-textured sports watches.

Navigating the watch is as easy as rotating the crown button through the various displays and pressing in to make selections. There is no back button, so you must scroll through the available screens in each widget to get to the back option on the display and return to the original main display carousel.

The ScanWatch 2 is built with a 5 ATM level of water resistance, so I was able to wear it while running in the rain. If you are a swimmer or surfer, you can wear it and track those activities in the water as well.

Withings states that the ScanWatch 2 charges up in two hours and may last up to 30 days. I can confirm the charging time is accurate, but I haven’t been using the wearable on “watch mode” only, so I can’t confirm the 30-day battery life. I ran with the watch several times while training for a marathon and connected it to my phone to test the connected GPS capability. When you use it for an activity, especially with connected GPS, the battery life will be significantly reduced. 

On a positive note, I’ve been able to wear the watch much longer than my usual fitness trackers. I once took it on three runs, varying from 35 to 55 minutes, and saw the watch still last for over a week before I had to charge it up.

The Withings smartphone application is surprisingly powerful and can share its collected data with Apple Health, Google Health Connect, and Google Fit. The application also brings in data from other Withings devices, including its scales, blood pressure monitors, and more so a full view of your entire physical state is available in the app. The watch will store up to seven days of data, so I suggest syncing it at least once a week.

On the app, skin temperature changes are shown at the bottom of your daily activity metrics (it initially took me a while to find where this skin data was being presented) with a baseline plot and minimum and maximum changes throughout the day. This information may be used when working out in warm environments where heat exhaustion may be a concern. The only thing missing here is longer-term trends for body temperature, which I have my fingers crossed that Withings will add in a future software update.

The ScanWatch 2 can also perform an ECG assessment, measure blood oxygen levels, track heart rate throughout the day, measure sleep, and track general physical activity. One gripe I have with the sleep tracking on the watch is that it can’t distinguish between deep and REM sleep, so it’s not the most informative sleep-tracking device available today.

Lastly, in addition to the watch, Withings launched a subscription service similar to Fitbit Premium, where additional insights and metrics are provided at a cost. The service also includes “Missions” intended to help inspire you to move or eat well, while other modules will aid you in building better fitness habits, such as improving your sleep scores. The monthly subscription is available for $9.95 or $99.50 per year.
