2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerGarmin fēnix 8 (47mm AMOLED) vs Withings ScanWatch Nova
The Garmin fēnix 8 (47mm AMOLED) is the flagship option here, boasting a vibrant 1.4" AMOLED display and advanced multisport features. You'll appreciate its 16-day battery life, perfect for those who need durability without constant charging. On the other hand, the Withings ScanWatch Nova offers a stylish design and clinical-grade health monitoring but only lasts 30 days on a single charge. What matters most here is how these watches fit your lifestyle. The Garmin fēnix 8 excels with its built-in GPS for serious athletes, while the Withings ScanWatch Nova is ideal for casual users who prioritize health metrics in a sleek package. In practical terms, that means real-time tracking for the fēnix 8, while the ScanWatch relies on your phone for GPS functionality, which could be a dealbreaker for some.
