Our take
The Withings ScanWatch Nova scores 79/100 and might be the only smartwatch your non-techy parents or watch-collecting friends would actually wear willingly โ because it looks like a genuine luxury diver's watch, not a miniature smartphone strapped to your wrist.
Medical-grade ECG for atrial fibrillation detection, continuous blood oxygen monitoring, temperature tracking, respiratory health analysis, and the HealthSense 4 platform monitoring 35 distinct health parameters โ all hidden behind elegant analog watch dials and a tiny, understated OLED display. 30-day battery life. Yes, thirty actual days on a single charge. Build quality: 90/100 in stainless steel with 100-meter water resistance. Works with both iOS and Android equally well. No mandatory subscription for any core health features.
The limitation is that tiny OLED screen: no apps, no music storage, no real smart notifications beyond basic alerts. This is a comprehensive health monitor disguised as a traditional luxury timepiece, not a smartwatch in the Apple or Samsung sense. Against the Apple Watch Ultra 3 or Galaxy Watch Ultra, it loses on every "smart" metric handily. But it wins on battery life by a factor of 10 and on aesthetics by a mile in traditional watch circles.
At $499.95 from Best Buy, the lowest recorded price is $449.95. Previously listed at $599.95 on Withings' own store, so the Best Buy price represents a $100 savings over buying direct. "Fair price" momentum โ decent but not an extraordinary deal.
Bottom line: Buy if you want medical-grade health monitoring that doesn't scream "tech gadget" and lasts a month on one charge โ perfect for people who hate charging yet another device every night.
