|Sources: Amazon, ManufacturerSamsung Galaxy Watch6 Classic (47mm, Bluetooth) vs Withings ScanWatch Nova
If you're after a smartwatch that offers a stunning display and comprehensive health features, the Samsung Galaxy Watch6 Classic (47mm, Bluetooth) is the premium choice. It boasts a vibrant 1.5-inch Super AMOLED display and a battery life of 40 hours, which means you'll be charging it daily, but it delivers advanced health metrics like Body Composition and ECG. The Withings ScanWatch Nova shines with its impressive 30-day battery life, making it perfect for those who want to skip daily charging. However, it has a much smaller 0.63-inch display and lacks built-in GPS, requiring you to connect to your phone for tracking routes. So, while the Galaxy Watch6 Classic offers more features, the ScanWatch Nova excels in battery longevity and a sleek design.
