Withings ScanWatch 2 (2026): The Hybrid Smartwatch That Tracks Your Sleep — and Your Heart
The Withings ScanWatch 2 puts medical-grade ECG, SpO2, and body-temperature tracking on a classic analog dial with 30-day battery. We compare it to the Apple Watch Series 10, Garmin Venu 3, Fitbit Charge 6, and more for 2026.
TL;DR: The Withings ScanWatch 2 is the 2026 hybrid that finally made us reconsider the "gadget on your wrist" problem. A real analog dial, medical-grade ECG + SpO2 + temperature, sleep-apnea screening, and a 30-day battery — for people who want health data without the always-on screen. Shop the ScanWatch 2 →
The smartwatch market in 2026 has split in two. One camp wants a mini-phone strapped to their arm — notifications, apps, a glowing rectangle. The other camp, the one quietly growing, just wants to know their heart, sleep, and stress are OK without charging every night or looking like they're checking email on a date.
That second camp is exactly who the Withings ScanWatch 2 is built for. And it showed up everywhere in the tech trend feeds we monitor this cycle — reviewers keep coming back to it as the hybrid that "finally got the health part right."
What the ScanWatch 2 Actually Does
Under that classic watch face is a surprisingly serious health suite:
- Medical-grade ECG — single-lead electrocardiogram to flag atrial fibrillation, right from the wrist.
- SpO2 (blood oxygen) — continuous and overnight, useful for spotting breathing disruptions.
- Body-temperature tracking — trended overnight, a genuine signal for cycle and recovery insight.
- Sleep apnea screening — uses SpO2 + movement to estimate nighttime breathing disturbances.
- 30-day battery — yes, weeks, not nights.
That last point is the quiet superpower. A sleep tracker you have to charge before bed is a sleep tracker you'll stop using. The ScanWatch 2 just… stays on.

ScanWatch 2 vs the 2026 Field
We put it against the other wearables flooding our trend feeds this month:
Apple Watch Series 10
The best "smart" smartwatch, period — brightest display, deepest app ecosystem, great fitness. But it charges nightly, and its health story is more "fitness + notifications" than "passive medical insight." Pick it if you live in the Apple ecosystem and want a tiny phone. Shop Apple Watch Series 10 →
Garmin Venu 3
The training-powerhouse pick. Brilliant for runners and lifters who want HRV, training load, and multi-day battery. Less focused on ECG/medical-grade heart screening, more on performance. Shop Garmin Venu 3 →
Fitbit Charge 6
The no-bulk band. Best if you want heart-rate and sleep tracking with zero wrist real-estate. You lose the analog look and the ECG-grade hardware of the ScanWatch 2. Shop Fitbit Charge 6 →
Amazfit Bip 6
The budget surprise — long battery, solid sensors, a fraction of the price. Great starter wearable, but the build and medical credibility don't match Withings. Shop Amazfit Bip 6 →
Smart Ring (health tracker)
The "forget you're wearing it" option. Excellent for sleep, but you give up the screen, the dial, and the on-wrist ECG. Shop a smart ring →
Who Should Buy the ScanWatch 2
- You want health insight first, apps second.
- You're tired of nightly charging and want a watch that looks like a watch.
- You care about ECG, temperature, and sleep-apnea screening specifically.
- You use iOS or Android — both work.
If you're a hardcore athlete who lives in training metrics, the Garmin Venu 3 is the better tool. If you want the biggest app store on your wrist, it's the Apple Watch Series 10. But for the person who just wants to trust their wrist to notice something wrong, the ScanWatch 2 is the most comfortable, least intrusive answer we've tested in 2026.
The Verdict
Hybrid smartwatches used to mean compromise: analog looks, weak sensors. The Withings ScanWatch 2 closes that gap — real medical-grade sensing, a 30-day battery, and a design you'd wear to dinner. It's the hybrid we keep recommending from this cycle's trend feeds.
