Its defining trade-off is what it leaves out: it does not offer ECG or blood oxygen measurement. If either is essential, compare the ScanWatch 2 or another watch that explicitly includes those features.
What the ScanWatch Light offers
The ScanWatch Light combines conventional watch styling with a small OLED sub-display for digital information. Withings lists a 37 mm stainless-steel case and crown, Gorilla Glass, a 9.85 mm case thickness and an FKM band. The 18 mm bands are interchangeable. It works with iOS and Android and can display incoming calls and app or message notifications. See the Withings ScanWatch Light product listing for current configurations.

Health and activity features
Withings lists activity and calorie tracking, automatic activity detection, workout mode, sleep tracking, smart wake-up, breathing quality index, cycle tracking and continuous heart-rate tracking. High- and low-heart-rate notifications are also included. These are product features, not a substitute for medical evaluation; the presence of a notification does not mean the watch can diagnose a condition.

What it does not measure
In Withings’ model comparison, the Light lacks ECG, blood oxygen measurement, overnight HRV, REM sleep, temperature tracking and elevation. Those omissions matter more than the general “health watch” label: this is a core tracking model rather than the brand’s option for people seeking those additional measurements. Withings positions the ScanWatch 2 with ECG and blood oxygen capabilities; check the ScanWatch 2 versus ScanWatch Light comparison for the current model-by-model feature list.

ScanWatch Light vs. ScanWatch 2
| Consideration | ScanWatch Light | ScanWatch 2 |
|---|---|---|
| ECG and blood oxygen | Not available, according to Withings’ comparison | Listed by Withings as supported |
| Other listed tracking | Core activity, sleep, heart-rate and cycle tracking | Comparison lists additional measurements and metrics, including overnight HRV, REM sleep, temperature tracking and elevation |
| Battery claim | Up to 35 days, advertised maximum | Not stated here; check the current model listing |
| Design details | 37 mm case, Gorilla Glass | Variants differ in size and materials; compare the exact version |
| US price | US$249.95 on Withings’ US listing when checked in 2026; current price may differ | Not stated here; check the current listing |
The comparison is about stated features, not proof that either model measures them more accurately. Choose the Light if its simpler feature set suits you; look at the ScanWatch 2 if ECG, blood oxygen or the additional listed metrics are priorities.
Battery life and charging
Withings advertises up to 35 days of battery life and approximately two hours for fast charging. “Up to” is a maximum claim, not a promise of typical results: usage and settings affect battery life. Withings’ ScanWatch Light battery-life support page provides further guidance. These figures are manufacturer claims, not independent real-world test results.

Water resistance, fit and compatibility
Withings rates the watch at 5 ATM (50 m) and describes it as swimproof. That rating does not establish suitability for diving or other activities beyond the manufacturer’s stated guidance. The 37 mm case and 18 mm interchangeable-band format are useful fit details to check before buying; confirm that the dimensions and exact band listing suit your wrist and preferred style.

There is an important limit to this review: the available independent review cited here is of the ScanWatch 2, not the Light. It cannot establish the Light’s comfort, accuracy, sleep staging, step counting or everyday battery performance. Withings’ specifications are useful for identifying what the company says the watch includes, but they are not independent validation.
