Amazfit GTR 4 vs Withings ScanWatch
The Verdict
Amazfit GTR 4 and Withings ScanWatch serve different smartwatch philosophies. Amazfit prioritizes digital features with its 46mm AMOLED display at 466x466 resolution, built-in GPS, and Zepp OS 2.0 platform offering comprehensive fitness tracking apps. Its 14-day battery life is respectable for AMOLED technology. Withings ScanWatch takes a hybrid approach, combining a classic analog watch face with a small PMOLED screen, sacrificing GPS but gaining exceptional 30-day battery life and ECG capability for heart rhythm detection. Build quality favors Withings with sapphire crystal and stainless steel construction versus Amazfit's aluminum case. For fitness enthusiasts wanting GPS-enabled workouts, route mapping, and vibrant always-on displays, Amazfit delivers better value at $199. However, if you prefer traditional watch aesthetics, medical-grade ECG monitoring, and minimal charging hassle, Withings ScanWatch justifies its $299 premium. The decision hinges on whether you need fitness features (Amazfit) or medical sensors with longer battery life (Withings). Amazfit edges ahead overall due to superior display technology and GPS integration at a significantly lower price point.
