Hybrid~$370Withings
Behind analog hands and sapphire glass, ScanWatch 2 records a single-lead ECG in 30 seconds from a finger on the steel bezel, and Withings' ECG App is FDA-cleared to detect atrial fibrillation. It adds 24/7 temperature-variation tracking, overnight HRV, on-demand SpO2 and an altimeter that ScanWatch Light leaves out. Withings rates it at up to 35 days per charge in 38 mm or 42 mm cases.

~$370
maker's list price, not a live price
Best for: People who want ECG and overnight health tracking in a watch that looks like a regular analog piece.
The ring’s outer track is the headline claim; the inner two are the always-on and GPS figures as a share of it. An empty track means Withings does not publish that figure. Why the figures differ
A clearance says what a feature is allowed to claim, not that it replaces a doctor. Cleared versus wellness features
What the extra money buys: Against the Withings ScanWatch Light, the extra ~$120 buys more cleared health features and more case sizes. See the Withings ScanWatch Light.
The two lists above are drawn from the maker’s own pages and prices, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
From what 11 owners of the Withings ScanWatch 2 reported between July and October 2026. Earlier generations are not counted.
Owners who like the ScanWatch 2 like it for being a normal-looking watch that tracks health quietly. One owner wore it daily for almost three years and only missed GPS and a find-my-phone button, and newer owners say they are happy with it so far.
The recurring complaint is that it does not know when it is off your wrist. Owners report sleep being recorded while the watch lay on the bed, heart rate and temperature readings with the watch on the nightstand, and irregular-rhythm alerts while it was not being worn, with no off switch to stop it. Battery and charging reports are mixed: one long-term owner's battery collapsed after the watch sat unused for three months and Withings told him it cannot be replaced, while another fixed charging that stalled at 10 percent with a reset. Smaller software quirks show up in workout summaries, calorie totals and notifications.
It fits people who want health tracking in a dress-watch body and who wear it most of the time. If you take your watch off often, plan for the off-wrist readings to land in your data.
Not according to owners. Several have seen sleep, heart rate, temperature and even irregular-rhythm readings recorded while the watch was on a bed or table, and there is no setting to turn the watch off.
One owner whose battery degraded after almost three years was told by Withings customer service that the battery cannot be replaced.
