2026 comparison

|Sources: Amazon, ManufacturerCOROS VERTIX 2S vs Withings ScanWatch Nova
The COROS VERTIX 2S is the better buy for most people due to its massive 118 hours of GPS battery life, making it a no-brainer for adventurers or anyone needing prolonged usage without frequent charging. In real-world use, that means you can tackle long hikes or runs without worrying about battery drain. On the other hand, the Withings ScanWatch Nova shines with its elegant design and clinical-grade health sensors, perfect for those who prioritize aesthetics and health tracking over extreme battery life. While it lasts up to 30 days, you'll need to pair it with your phone for GPS, which can be limiting for outdoor enthusiasts. The trade-off here is clear: luxury and health metrics versus rugged endurance and battery longevity.
