Huawei Watch GT 3 Pro vs Withings ScanWatch
The Verdict
Both watches excel at health tracking with ECG and SpO2 monitoring, but serve different priorities. Huawei Watch GT 3 Pro offers a larger 46mm AMOLED display with 466x466 resolution, delivering vibrant always-on visuals and GPS for standalone navigation. Its titanium case feels premium at 54g, and 14-day battery is respectable for a smartwatch. Withings ScanWatch takes a different approach with a 42mm hybrid analog-digital design, featuring a traditional watch face with a small PMOLED screen. Its standout advantage is exceptional 30-day battery life, nearly double the Huawei's endurance. Withings includes WiFi connectivity for broader internet access, while Huawei offers GPS and NFC for contactless payments. The Huawei costs $70 more but delivers a full smartwatch experience with extensive customization. Withings appeals to those preferring classic watch aesthetics and minimal daily charging. Health tracking is comparable between both, though Huawei adds skin temperature sensing. Choose the GT 3 Pro if you want a modern, feature-rich display and don't mind charging weekly. Pick the ScanWatch if you prefer traditional watchmaking, extended battery life, and a subtler tech presence. The decision hinges on whether you prioritize smartwatch features or classic design with longevity.
