2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerWithings ScanWatch Nova vs Google Pixel Watch 4 (45mm)
The Withings ScanWatch Nova is the premium option here, but the Google Pixel Watch 4 (45mm) is a flagship that packs in features. You'll be surprised that the Pixel Watch's 40-hour battery life crushes the ScanWatch Nova's 30-day claim, making it a better fit for daily wear in 2026. In real-world use, the ScanWatch Nova's clinical-grade health sensors are impressive, but its small 0.63-inch monochrome display limits functionality. You'll find that the Pixel's 1.4-inch AMOLED display shines bright at 3,000 nits, making notifications and apps far more readable. If fitness tracking is your focus, the ScanWatch excels, but the Pixel Watch offers more versatility for everyday smart uses.
