Withings ScanWatch 2 review

The ScanWatch 2 looks like a traditional watch, with real hands and a 0.63-inch OLED window for data and alerts. That design gives it the longest battery on this list by a wide margin: Withings rates it at up to 35 days, and a full charge takes about 2 hours. Health tracking is serious for its size. Resting a finger on the bezel records a single-lead ECG in 30 seconds and checks for atrial fibrillation, and the watch tracks temperature around the clock, overnight HRV, REM sleep, blood oxygen and a Breathing Quality Index. It shows incoming calls and app and message notifications on both iPhone and Android. The tradeoff is that it is not a full smartwatch. You cannot reply to messages or install apps, and Withings does not list contactless payments. At $369.95 it costs more than several touchscreen picks, so it only makes sense if you want the look of a classic watch and rarely want to charge it.

Who it is for
