Withings Scanwatch 2 is an interesting hybrid device because it looks like a regular watch (complete with analog hands), but it has features you typically see on smartwatches, like an OLED screen and health tracking features.
How often do you charge your smartwatch? Once or twice every day? too often? Doing this regularly often surprises me how much value I’m really getting from those occasional notifications and alerts, and it’s a big reason I’m still fond of hybrid smartwatches.

One of the first is the Withings Scanwatch, which was released in 2021. I’ve worn it regularly over the past few years, mainly because it feels great on the wrist while capturing key health data. Each charge can last for one month.

At first glance, new scanwatch 2 It’s hard to differentiate it from the original, but it includes some significant upgrades that make one of my favorite health trackers even better.

I tested the ScanWatch 2 in black (pictured below), but it’s also available in pearl white for larger sizes. The hands of the black model have a Super LumiNova coating that makes them glow in the dark for a short period of time after exposure to light. If you prefer the smaller 38mm size, it’s available in Pearl White, Black, Sand and Blue. Interestingly, both sizes cost $349, so you don’t have to pay more for the larger watch face, which is good.
The 42mm Scanwatch 2 I’m wearing weighs about 52 grams and fits comfortably 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 is 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 is a beauty to behold. So avoid this if you like rugged, multi-texture sports watches.
Navigating the watch is as easy as rotating the crown button through the different displays and pressing to select. There is no back button, so you have to scroll through the screens available 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’re a swimmer or surfer, you can wear it and track those activities in the water as well.
Withings says the ScanWatch 2 charges in two hours and can last up to 30 days. I can confirm that the charging time is accurate, but I’m not using the wearable, only on “watch mode,” so I can’t confirm the 30-day battery life. While training for a marathon I ran with the watch several times and connected it to my phone to test the connected GPS capability. When you use it for any activity, especially with a connected GPS, the battery life will reduce significantly.
One positive is that I’m able to wear the watch for longer periods of time than my usual fitness tracker. Once I ran it three times, which was between 35 and 55 minutes, and saw the watch still last for over a week before I had to charge it.
The Withings smartphone application is surprisingly powerful and can share its collected data with Apple Health, Google Health Connect, and Google Fit. The app also brings data from other Withings devices, including its scales, blood pressure monitors, and more, giving a complete view of your entire physical condition right in the app. The watch will store up to seven days’ worth of data, so I recommend syncing it at least once a week.

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

The ScanWatch 2 can also perform ECG assessments, measure blood oxygen levels, track heart rate throughout the day, measure sleep, and track general physical activity. My one complaint about the sleep tracking on the watch is that it can’t differentiate between deep and REM sleep, so it’s not the most informative sleep-tracking device available today.

Finally, in addition to the watch, Withings launched a subscription service similar to Fitbit Premium, where additional insights and metrics on cost are provided. The service also includes “missions” aimed at helping you motivate yourself to move or eat better, while other modules will help you form better fitness habits, such as improving your sleep scores. Monthly subscriptions are available for $9.95 or $99.50 per year.
ZDNET’s shopping advice
is not only Withings Scanwatch 2 A great watch thanks to its always-on analog hands, but it looks great on the wrist, has a long battery life, and measures the key health and wellness data you need to help improve your lifestyle. At $349, the smartwatch is reasonably priced and competes well with other hybrid watches I’ve tested.
