Key Features
Clinical-Grade Sleep Tracking
Tracks sleep stages, breathing disturbances, heart rate, and SpO2 overnight. Withings’ Sleep Diary view is one of the cleaner-looking dashboards in this category. Prefer something on your finger instead of your wrist? Our smart ring sleep tracker roundup covers the other route.
Sleep Apnea Screening
The respiratory scan can flag breathing disturbance patterns, a real screening signal, not just a marketing line. Useful for people who suspect untreated apnea.
30-Day Battery Life
You charge it once a month. No nightly routine of remembering to plug a wearable in before bed.
Looks Like a Real Watch
Hybrid analog face with a small digital sub-display. You can wear it to a dinner without anyone asking why you’re wearing fitness tech.

Final Verdict
The Withings ScanWatch Nova is the sleep watch for people who don’t want to wear a sleep watch. It looks like an analog timepiece, lasts a month per charge, and the respiratory-disturbance screening is a feature that matters. It costs more than most rings or bands, but for the right buyer, it’s the only one that does all three of those things at once.
