2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerSamsung Galaxy Watch 7 vs Withings ScanWatch Nova
The Samsung Galaxy Watch 7 outshines the Withings ScanWatch Nova in performance and features, making it the better choice for most users. With a cutting-edge 3nm Exynos W1000 chip, it offers snappy responsiveness, while the ScanWatch Nova's hybrid design appeals to those prioritizing battery life with an impressive 30 days on standard use. In real-world use, the Galaxy Watch 7's dual-frequency GPS provides superior tracking accuracy, crucial for urban environments. Meanwhile, the ScanWatch's elegant aesthetic and clinical-grade health sensors make it appealing, but you'll sacrifice functionality with its limited smart features and monochrome display. If you need extensive health metrics and performance, the Samsung is a no-brainer, but the Withings is worth considering for long battery life and style.
